2. COMPONENT INFORMATION:

The compositions of individual products in the alloy families or categories listed under 1.1 are given in the product composition tables in
APPENDIX 1. Please refer to the appropriate alloy name or designation.


3. HAZARDS IDENTIFICATION:

Description of hazards:
As shipped, these complex alloys in massive form have no known toxicological properties other than causing allergic reactions in individuals
sensitive to the metals contained in the alloys. Nickel, Cobalt, and some forms of Chromium are known skin sensitizers. Nickel and Cobalt
also are classified as suspected carcinogens (EU Category 3). Absent specific test data for the alloy, mixtures (including alloys) that contain
more than 1% of a substance are classified in the same manner as that substance.

Hazardous fume or dust emissions may be released during remelting, grinding, cutting, or welding. In addition to Nickel and Cobalt,
Hexavalent Chromium (a known human inhalation carcinogen - EU Category 2) may be generated during processing activities. If airborne
emissions are excessive, inhalation may affect worker health. Further information is given in Section 8 - Exposure Controls / Personal
Protection.

In addition, individual products in the above alloy families may contain one or more of the following ingredients, which may be considered
hazardous under the legislation indicated:

USA: SARA SECTION 313 SUPPLIER NOTIFICATION: Emergency Planning and Community Right-To-Know Act of 1986 and of 40 CFR 372.

Refer to APPENDIX 1 of this MSDS for the individual alloy name and the percent by weight of the various ingredients in each alloy.
Refer to APPENDIX 2 for detailed information on the toxicological properties of these ingredients.


4. FIRST AID MEASURES:
Eye contact: Flush particles from the eyes with clean water for at least 15 minutes. If irritation persists, seek medical help.
Skin contact: Wash skin with soap and water to remove any metallic particles. If a rash develops, seek medical attention.
Inhalation: Remove from exposure. If respiratory irritation persists, seek medical help.
Ingestion: If symptoms of ingestion arise, seek medical help.


5. FIRE or EXPLOSION HAZARD: Nonflammable, however sparks from welding or grinding in user operations could ignite flammable or
combustible liquids, vapors and solids.


6. ACCIDENTAL RELEASE MEASURES:
Vacuum or shovel any spilled material into a suitable container. Alloy wastes are normally collected to recover metal values.


7. HANDLING AND STORAGE:
Under normal circumstances the materials do not produce any hazardous products and as such do not require any special precautions.
However, see Section 10, "STABILITY AND REACTIVITY". The transient handling of the materials would not be expected to produce any
sensitization but it is good practice to use gloves for handling. The normal precautions for handling heavy objects with possible sharp edges
should also be observed.


8. EXPOSURE CONTROLS / PERSONAL PROTECTION:

Respiratory Protection: Respiratory protection is necessary when exposure limits for airborne contaminants are exceeded during cutting,
grinding or welding on these alloys. Use air-supplied respirator in confined spaces. In the USA, use only NIOSH-approved respirators in
accordance with 29 CFR 1910.134, or other nationally approved respirators. In the EU if required use protection to EN136 (full face
respirators), EN140 (half mask respirators), EN149 (filtered half masks (disposable)) or other appropriate EN standard. In the rest of the world
use respiratory protection to the appropriate national standard.

Ventilation: Use local exhaust ventilation when cutting, grinding or welding. Maintain exposures below published exposure limits. Confined
spaces require special attention to provision of adequate ventilation and/or air-supplied respirators.

Special Metals Corporation Material Safety Data Sheet


Eye Protection and Protective Clothing: Eye protection is recommended when cutting, grinding and welding. Wear gloves, face protection
and flame retardant clothing. Do not expose skin or eyes to the heat and radiation from welding operations.


IMPORTANT
Maintain exposures below the published exposure levels. Use industrial hygiene air monitoring to ensure that your use of this material does
not create exposures that exceed the recommended exposure limits. Always use exhaust ventilation in user operations such as high
temperature cutting, welding and grinding. Refer to the following sources for important additional information:

In U.S.A.: 29 CFR 1910, ANSI Z49.1 , American Welding Society, OSHA, U.S. Dept of Labor
In Canada: Canadian Standards Association, CAN/CSA - W17.2-M87
In UK: Current exposure limits under Health & Safety Executive EH40 are given in Appendix 2.


9. PHYSICAL AND CHEMICAL PROPERTIES:
Physical State: Solid Specific Gravity: 8-9 gm/cc Melting Point: >1260 属C Odor: Odorless
Appearance: Silver-colored metal shaped as plate, bar, wire, tube, rod, strip, sheet or some intermediate form.

Other physical and chemical properties, e.g. as described in 91/155/EEC and in the Approved Code of Practice, ref. 11 (viscosity, flash point,
autoflammability, vapor pressure, solubility and partition coefficient), have no safety implications in relation to these materials.


10. STABILITY AND REACTIVITY:
These alloys are very stable and no hazardous decomposition products are formed upon exposure to water or the atmosphere. Nickel can
react with carbon monoxide in reducing atmospheres to form nickel carbonyl, an extremely toxic gas.


11. TOXICOLOGICAL PROPERTIES:
Nickel and cobalt are classified as Category 3 carcinogens. The exposure route of concern is inhalation. Hexavalent Chromium (a known
human inhalation carcinogen - EU Category 2) may be generated during processing activities.

As shipped, these complex alloys in massive form have no known toxicological properties other than causing allergic reactions in individuals
sensitive to the metal(s) contained in the alloys. However, user-generated dusts and fumes may on contact with the skin or eyes produce
mechanical irritation. Chronic exposures coupled with sweat could cause dermatitis (skin) or conjunctivitis (eyes). Excessive inhalation of
user-generated fumes from high temperature cutting, remelting or welding of these alloys may, depending on the specific features of the
process used, pose a long-term health hazard. The International Agency for Research on Cancer (IARC) has concluded that welding fumes
are possibly carcinogenic to humans.

The ingredients of fumes and gases generated in user welding, grinding and high temperature cutting operations will depend on the base
metal, electrode, flux and the specific process being used. Ingredients may include metals, metal oxides, chromates, fluorides, carbon
monoxide, ozone, and oxides of nitrogen. Phosgene can be produced if chlorinated solvent vapors are present in user operations.

More detailed toxicological information is given in APPENDIX 2.


12. ECOLOGICAL EFFECTS:
These alloys are not soluble in water and react only very slowly with natural environments. No special precautions are necessary.


13. DISPOSAL:
Alloy wastes are normally collected to recover metal values. However, if disposal is necessary, dispose of in accordance with national, federal,
state or local regulations. In the UK, most alloy material would be classified as special waste.


14. TRANSPORTATION:
No special precautions are necessary for the transport of these materials.


15. REGULATORY INFORMATION:
Classification and labelling requirements
Alloys containing less than 1% of nickel or cobalt are not classified as "dangerous for supply". Alloys containing more than 1% of either metal
are classified as the metals themselves (see Section 3). However, in recognition of their essentially non-hazardous nature, these alloys in the
massive form are not required to be labeled as hazardous.

PEL: 15 mg/m3 (Total metal dust); 5 mg/m3 (Metal dust - respirable fraction)
CAS No.(2): 7429-90-5
LD50: Not Available
Aluminum is not readily absorbed through the skin or the GI tract and only poorly through the lungs. Foreign literature
between 1958 and 1962 reported cases of severe and sometimes fatal pulmonary fibrosis in workers exposed to aluminum
dust. In one of the fatal cases, the worker developed fibrosis and encephalopathy after 13.5 years of exposure to aluminum
dust.
In rodent studies and currently in US industry, no fibrosis or encephalopathy have been reported from the inhalation of
aluminum powder. Acute exposure to alumina fume may cause bronchial irritation, however reports of pulmonary fibrosis
and emphysema in alumina abrasive workers are no longer seen, owing to improved environmental control.
EH40 - Aluminium metal:
Total inhalable dust OES 10 mg/m3 (8 hours TWA) Total respirable dust OES 4 mg/m3 (8 hours TWA)

Chromium (Cr)
Exposure Limits(1): TLV: 0.5 mg/m3
PEL: 1.0 mg/m3 (Metal as Cr); 1 ug/m3 (8 hours TWA) (Chromium VI compounds)
CAS No.(2): 7440-47-3
LD50: Not Available
Chromium metal is relatively nontoxic. Chromium metal and insoluble salts are said to be involved in fibrosis of the lungs.
When the metal is heated to a high temperature, fumes produced may be damaging to the lungs if inhaled. The International
Agency for Research on Cancer has concluded that the evidence for carcinogenicity in humans and animals is inadequate for
chromium metal and trivalent chromium compounds, but sufficient for hexavalent chromium compounds. Fumes from
welding chromium-containing stainless steel or certain chromium-containing rods can trigger eczematous eruptions on the
palms of the hands of chromium-sensitized individuals.
EH40 - Chromium:
Chromium VI compounds (as Chrome) MEL 0.05 mg/m3 (8 hours TWA)
Chromium II compounds (as Chrome) OES 0.5 mg/m3 (8 hours TWA)

CAS No.(2): 7440-48-4
LD50: 6,170 mg/kg, rat, oral
Asthmatic symptoms and pulmonary fibrosis occurring in the tungsten carbide industry may be related to the inhalation of
metallic cobalt dust. Evidence of polycythemia (an increase in the total red cell mass of the blood in the body) and altered
thyroid, kidney and liver function have also been found. Excessive inhalation of metallic cobalt have produced cardiac
changes in miniature swine. Eye contact may cause conjunctivitis. Symptoms of excessive ingestion may be a sensation of
hotness with vomiting, diarrhea and nausea along with the potential for causing damage to blood, heart, thyroid and pancreas.
Repeated skin contact can cause sensitivity and allergic skin rashes. Cobalt powders have caused tumors at the site of injection
in rodents. However, studies of cobalt-containing prostheses do not suggest a significant risk for humans.

CAS No.(2): 7440-50-8
LD50: 35 mg/kg, mouse, intraperitoneal
Copper metal dust and fume may be irritating to the respiratory tract. In user operations where copper fume is generated,
inhalation of the fume can result in symptoms of "Metal Fume Fever" such as chills, fever and sweating. A few instances of
allergic skin rashes have been reported in workers with skin exposure to metallic copper. In the eyes, copper metal as a foreign
body can provoke an inflammatory reaction resulting in pus formation in the conjunctiva, cornea or sclera. Ingestion of copper
metal may cause gastrointestinal upset. Wilson's disease can occur in certain individuals with a rare, inherited metabolic
disorder characterized by retention of excessive amounts of copper in the liver, brain, kidneys and corneas. These deposits
eventually lead to tissue necrosis and fibrosis, causing a variety of clinical effects, especially liver disease and neurological
changes. Wilson's disease is progressive and, if untreated, leads to fatal liver failure.
EH40: Fume OES 0.2 mg/m3 (8 hours TWA)

Excessive inhalation or ingestion of manganese can produce manganese poisoning. Chronic exposures can lead to
neurological problems such as apathy, drowsiness, weakness, spastic gait, paralysis, and other neurological problems
resembling Parkinsonism. These symptoms can become progressive and permanent if not treated. Excessive inhalation of
fumes may cause "Metal Fume Fever" with its flu-like symptoms, such as chills, fever, body aches, vomiting, sweating, etc.
EH40 - Fume (as Mn) OES 1.0 mg/m3 (8 hours TWA), 3.0 mg/m3 (15 minute reference period)

Nickel (Ni)
Exposure Limits(1): TLV: 1.5 mg/m3 as metal (Inhalable Fraction)
PEL: 1 mg/m3 for metal and insoluble compounds as Ni
CAS No.(2): 7440-02-0
LD50: >9,000 mg/kg, rat, oral
The U.S. National Toxicology Program (NTP) 10th Report on Carcinogens has listed "metallic nickel" as "reasonably
anticipated to be a human carcinogen" and "nickel compounds" as "known human carcinogens". "Nickel Alloys" were
reviewed but not listed. The International Agency for Research on Cancer (IARC) concluded that nickel compounds were
carcinogenic to humans and that metallic nickel is possibly carcinogenic to humans. Epidemiological studies of workers
exposed to nickel powder and to dust and fume generated in the production of nickel alloys and of stainless steel have not
indicated the presence of a significant respiratory cancer hazard.
The inhalation of nickel powder has not resulted in an increased incidence of malignant tumors in rodents. Repeated
intratracheal instillation of nickel powder produced an increased incidence of malignant lung tumors in rats, but did not
produce an increased incidence in hamsters when administered at the maximum tolerated dose. However, single intratracheal
instillations of nickel powder in hamsters at doses near the LD50 have produced an increased incidence of fibrosarcomas,
mesotheliomas and rhabdomyosarcomas. Inhalation of nickel powder at concentrations 15 times the PEL irritated the
respiratory tract in rodents. Nickel is a known sensitizer and may produce allergic reactions.
EH40 - Nickel and its inorganic compounds (except nickel carbonyl):
Water soluble nickel compounds (as nickel) MEL 0.1 mg/m3 (8 hours TWA)

Niobium (Nb)
