Description

CS Alloys Shield 203 is a cadmium-free, eutectic alloy with a melting temperature of 203°F (95°C) and a density of 0.351 lbs./in3 (9.71 g/cc). It's used in shielding during medical radiation treatments. Here are some other low melting alloys: *MELLOTTES Metal: A bismuth-based eutectic alloy that's cadmium-free *Alloy-203: A cadmium-free, fusible lead alloy that's suitable for radiotherapy shielding blocks *Cerrotru Alloy: A cadmium-free, fusible alloy that's a low melting alternative for LOW 158 for nuclear medicine Alloys are mixtures of pure metals. The different sizes of atoms in an alloy make their arrangement less regular than a pure metal, which makes the bonds between the atoms weaker and lowers the melting point.
