Bismuth alloy

from Wikipedia, the free encyclopedia

Bismuth (only in minerals than bismuth hereinafter) in addition to cadmium , gallium and indium is used for low-melting alloys.

Walker alloy 45 28 22nd - - 05
Cerrolow 174 57 - 17th - 26th - 78.9 ° C
Fieldsmetall 32 - 17th - 51 - 62 ° C
1The specified alloys may have a melting range because they do not always hit the eutectic .
2Cerrolow 104 with a melting temperature of 40 ° C. is obtained by adding mercury.
By adding thallium, on the other hand, a eutectic is obtained that melts at 41.5 ° C.
