Sourcing Low Melting Alloys



I was wondering if anybody ever heard of a metal called Spencermetal it is said to resemble wood-metal and was used in the dental industry. I'm looking for a low melting (100-150 degrees) alloy for filling cavities in a mould. It does not have to have any special qualities besides having a low melting point and a reasonable hardness. Hope someone can help me.

Hello Caroline!

Low melting alloys commonly contain indium or bismuth, so you can probably find what you seek at manufacturers who use those elements. One that I can definitely recommend is Indium Corporation, at Their products are listed on their website, and you can easily find one whose melting point meets your needs. Hardness may be another story, as indium, bismuth, lead, tin, etc are all pretty soft.

Good luck!
