Bismuth Manganese

Chemical Formula Available Form Description of the Product
Bi- 88-90%, Mn- 4-6% Dia = 9, 13 mm Cored Wire Small amounts of bismuth are used to enhance the machinability of metals, especially steel, a use fostered by concern about the toxicity of lead, a traditional free machining additive for this purpose. Bismuth has been used both as an additive to resulfurized, rephosphorized, and leaded AISI 1214 steel and as a substitute for lead in AISI 1214 and 1215 steels.
