Cerrolow 136

Cerrolow 136, is a fusible alloy that becomes liquid at approximately 58 °C (136 °F). It is a eutectic alloy of bismuth, lead, indium, and tin, with the following percentages by weight: 49% Bi, 18% Pb, 21% In, 12% Sn.

It is also known as ChipQuik desoldering alloy.[1] and Lens Alloy 136, used for mounting lenses and other optical components for grinding.[2] Used for mounting small delicate oddly-shaped components for machining. It slightly expands on cooling, later shows slight shrinkage in couple hours afterwards. Used as a solder in low-temperature physics.^[citation needed]

The Young's Modulus is approximately 2.5×10^6 psi (17.24 GPa) [3]
