Casting Alloy 34
Lead-Based Alloy for Thin-Walled Model Kits
Casting Alloy 34 is a specialist lead-based alloy engineered for the thin wall sections commonly found in model kits and complex castings. The precise addition of bismuth minimises shrinkage, ensuring castings remain dimensionally accurate with excellent surface quality. Designed for stability on large, flat surfaces, it provides low malleability and robust casting performance even for challenging geometries.
