This specification covers requirements for electrodeposited palladium-cobalt alloy coatings containing approximately 80 % of palladium and 20 % of cobalt. Composite coatings consisting of palladium-cobalt with a thin gold overplate for applications involving electrical contacts...

This specification covers cobalt-coated tungsten carbide in the form of powder.

This specification covers the requirements for electrodeposited zinc cobalt alloy coatings on metals. The following precautionary caveat pertains to the test method portion only, Section 8, of this specification: This standard does not purport to address all of the safety concerns, if any,...

1.1 This practice covers the form and style for specifications under the jurisdiction of ASTM Subcommittee B02.07 Refined Nickel and Cobalt and Their Alloys. Anyone preparing new or revising existing specifications for this subcommittee shall follow the practices and procedures...

These test methods for the chemical analysis of metals and alloys are primarily intended as referee methods to test such materials for compliance with compositional specifications, particularly those under the jurisdiction of ASTM Committee B02 on Nonferrous Metals and Alloys. It is assumed...

This specification covers technically important, commercially available, magnetically hard sintered (fully dense) permanent magnets commonly known as samarium cobalt. These materials are available in two general composition families abbreviated "SmCo 1:5" and "SmCo 2:17." The numbers...

This specification covers cobalt-coated tungsten carbide in the form of powder.

This standard specifies a potentiometric method for the determination of the cobalt content of hardmetals.

This standard specifies a potentiometric method for the determination of the cobalt content of hardmetals.

This specification covers the chemical, mechanical, and metallurgical requirements for three wrought cobalt-28chromium-6molybdenum alloys used for surgical implants. The properties specified apply specifically to wrought bar, rod, and wire. The alloys shall conform to the prescribed chemical...

Nickel and cobalt alloys provide unique combinations of physical and mechanical properties and exceptional resistance to corrosion attack. If the need for these extraordinary properties were not critical to a variety of industrial applications, these alloys probably would not be manufactured...

This test method covers the determination of cobalt (expressed as the oxide) in fresh cobalt-molybdenum catalyst, in the range of 0.5 to 10 % cobalt oxide. The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard....

This specification covers rough and finished machined castings of cobalt-chromium-tungsten alloys for use where corrosion and wear resistant materials are required.

1.1 This specification covers cold-drawn cobalt alloy spring wire intended especially for the manufacture of springs. 1.1.1 This specification requires capability properties after age hardening test samples of the cold worked spring wire to ensure final mechanical properties are satisfied....

This method is for determining nickel, molybdenum, phosphorus and cobalt in fresh gamma-alumina supported catalysts; and nickel (Ni), molybdenum (Mo), phosphorus (P), cobalt (Co) and aluminum (Al) in fresh silica-alumina supported catalysts of known composition by Inductively Coupled...

This specification covers an iron-nickel-cobalt alloy, UNS K94610 containing nominally 29 % nickel, 17 % cobalt, and 53 % iron, in the forms of wire, rod, bar, strip, sheet, and tubing, intended primarily for sealing to glass in electronic applications. The values stated in inch-pound...

The amount of cobalt drier used in oxidizing-type coatings significantly affects their drying properties. This test method may be used to confirm the stated cobalt content of a pure liquid cobalt drier soluble in glacial acetic acid and manufactured for use by the coatings...
