ASTM B943-16(2022)

Annotation of standard text ASTM B943-16(2022) :

This specification covers zinc and tin alloy wire, including zinc-aluminum, zinc-aluminum-copper, zinc-tin, zinc-tin-copper an dtin-zinc, used as thermal spray wire in the electronics industry. The wire shall conform to the required chemical composition for cadmium, zinc, tin, lead, antimony, copper, aluminum, bismuth, arsenic, iron, nickel, and magnesium. The wire shall be clean and free of corrosion, adhering foreign material, scale, seams, nicks, burrs, and other defects which would interfere with the operation of thermal spraying equipment. The wire shall uncoil readily and be free of bends or kinks that would prevent its passage through the thermal spray gun. Sampling methodology should ensure that the sample slected for testing is representative of the matreial. The diameter of the wire shall be determines at the end and the beginning of each continuous wire.
