Description

Roto202F is a low melt fusible alloy that contains 62.5% bismuth and 37.5% tin. It's a lead-free alternative to Roto203F. An ingot of Roto202F weighs about 1 pound. Here are some uses for Roto202F: *Electroforming mandrels *Lost wax pattern dies *Holding jet turbine engine blades for machining Low melting alloys are often bismuth-based and can also contain lead, tin, antimony, gallium, cadmium, zinc, and indium. They have a low melting point and can be easily cast. They can be recycled and reused multiple times.
