Bismuth - Wikipedia

Bismuth is a chemical element with symbol Bi and atomic number 83. It is a pentavalent post-transition metal and one of the pnictogens with chemical properties resembling its lighter homologs arsenic and antimony.Elemental bismuth may occur naturally, although its sulfide and oxide form important commercial ores. The free element is 86% as dense as lead.It is a brittle metal with a silvery ...

Lead Free Bullet Casting Alloy (88%-Bismuth, 12%-tin)

This ratio of 88% Bismuth and 12% Tin is the best ratio we have come up with as a substitute for lead. This alloy melts at about 395 F and is best cast or poured at about 500F. Testing the hardness with a Lee Hardness Testing Kit, we came up with an average of 19.3 on the Brinnell Hardness Scale, although there was a range during the testing.

Bismuth vs. silicon in lead-free products :: Apollo Valves

Jul 10, 2018· While both copper-bismuth and copper-silicon alloys cast readily, machinability is a different matter. Bismuth aids metal cutting in much the same way as lead: it provides lubrication and acts as a chip-breaker. Silicon, however, dissolves in the copper-zinc alloy and increases hardness. The result is higher cutting forces and increased tool wear.
