Description

Low Melting Alloy BOLTON 203 is a eutectic alloy that contains bismuth, lead, and tin. It has a melting point of 203°F (95°C). Low melting alloys are also called fusible alloys. They can form a liquid or semi-liquid state at low temperatures and then re-solidify. This allows parts to be joined or cast at temperatures lower than 300°F. Here are some technical specifications for Low Melting Alloy BOLTON 203: *Melting point: 203°F (95°C) *Short-term tensile strength: 6100 lbs/sq.in *Yield temperature: 203°F *Weight: 0.35 lbs/cu.in *Brinnell hardness: 9 (500 kg) *Growth/shrinkage: -0.0002 after 2 minutes, 0.0055 after 1 hour Low melting alloys are usually used in gravity casting. They can also be used in other casting methods.
