Antimony (chemical element with the symbol Sb and atomic number 51) is a lustrous gray and brittle metalloid.
- Antimony and Antimony alloys are a great way to harden other metals such as lead and tin. Antimony melts at over 1100 Deg F, so it is ideal to harden a lead alloy.
- Typically, the largest applications for antimony are an alloy with lead and tin and the lead antimony plates in lead-acid batteries.
- Alloys of lead and tin with antimony have improved properties for solder, bullets, and plain bearings.
- Antimony compounds are prominent additives for chlorine and bromine-containing fire retardants.
