Bismuth

Used for modifying the casting charachteristics of alloys and lead. 10% Bismuth added to lead will reduce the melting point producing an alloy with an operating temperature between 260'c to 300'c. A 15% addition produces and alloy with an operating temperature between 230'c to 280'c. Adding bismuth to lead improves the casting characteristics of pure lead and also brings it within the working temperature of RTV65 silicone rubber. Contains only virgin Bismuth.
Melting point: 271'c
