AIM 138/170 CerroCAST      


This alloy is one of the most interesting in the range of low melting point Bismuth based alloys. On solidification from the molten state and thereafter, it exhibits practically no dimensional change - unlike other Bismuth alloys, most of which expand whilst a few contract on ageing.
