Title:Silver Alloy Brazing Filler Metal, 50Ag - 28Zn - 20Cu - 2.0Ni, 1220 to 1305 掳F (660 to 707 掳C) Solidus-Liquidus Range
Issuing Committee:Ams D Nonferrous Alloys Committee
Scope:The specification covers a silver alloy in the form of wire, rod, sheet, strip, foil, pig, powder, shot, and chips, and a viscous mixture (paste) of powder in a suitable binder. Primarily for joining ferrous metals, particularly austenitic steels and alloys, where high joint strength up to 400 degrees F (204 degrees F) is required, and for joining nonferrous metals except those having a base of aluminum or magnesium.【英文标准名称】:Copperandcopperalloys.Rodforgeneralpurposes
