Application areas of gallium alloys

Gallium and indium, thallium, tin, bismuth, zinc, etc. can form a series of low-melting alloys between 3 °C and 65 °C, which are used for temperature measurement and control, mercury substitutes in instruments, supports in beading operations, and metal coatings. Cooling circuits for layers, electronics and nuclear industries. For example, a gallium alloy containing 25% indium is a low melting point alloy that melts at 16°C and can be used in automatic fire extinguishing devices. Gallium and copper, nickel, tin, gold, etc. can form cold flux, which is suitable for difficult-to-weld special-shaped thin walls, cold welding between metals and between ceramics and cavity blocking.
