Specialty Alloys of Lead

Antimonial Lead

Antimonial Lead is produced by introducing Antimony into lead. Metallic antimony is a brittle metal with a crystalline texture. Antimony is a harder metal than lead. When combined with lead, it forms an alloy this is harder and/or firmer. The percentage of antimony in the alloys is dependent on your application and/or specifications.

S.R.L.P Antimonial lead is available in sheet, extrusions, and in casting.

Britannia Alloys

Britannia alloys, which are sometimes used for organ pipes, engraving metals or caskets, are available from our Britt Mill. This special mill produces a special required ultra smooth surfaces/high finished materials which are necessary in some of these applications.

Pure Tin

S.R.L.P. can supply pure tin bars, ingots, pipe, powders, circles, sheets and wires in various sizes and diameters. Special tin alloys are also available. Certificate of Analysis furnished upon request. Please contact us with your specifications.
