Product Overview
60% Tin Pewter Alloy is a tin-lead-antimony casting alloy with a nominal composition of 60% Sn, 37.5% Pb, and 2.5% Sb. The high tin content (60%) combined with the lead addition produces a lower melting temperature than most tin-base pewters, extending mold life in production rubber and metal mold spin casting by reducing thermal stress per cycle and lowering energy consumption per pour. The antimony addition provides the hardness and slight casting expansion characteristic of pewter alloys, ensuring good mold fill and sharp surface detail reproduction. The 60% Sn composition produces a brighter, whiter casting appearance than low-tin pewters (25-35% Sn) while remaining significantly less expensive than high-tin lead-free Britannia. Suitable for sculpture, decorative casting, and novelty objects where the lowest pouring temperature in the pewter range is the primary selection criterion and lead content is acceptable for the intended end use. Forms: 5-8 lb ingots.
