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^{[citation needed]}

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

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