Antimonial Lead
Antimonial lead is produced by adding Antimony to Lead. Antimony, number 51 on the Periodic Table of Elements, is a harder metal than lead, thus when mixed with lead, makes it harder and/or firmer. The percentage of Antimony depends upon your application or specifications. Antimonial lead can be supplied in multiple forms. Our dedicated staff can help you decide what is right for you.
| Stock Antimony Alloys | Lead (Pb) | Antimony (Sb) | Tin (Sn) | Other | |
|---|---|---|---|---|---|
| M1 | 98% min | 1.00 – 1.99% | max 1% | ||
| M4 | 95% min | 4.00 – 4.99% | max 1% | ||
| M6 | 93% min | 6.00 – 6.99% | max 1% |
