Indium Alloy Classification
Nov 25, 2021
Bearing alloy
Bearing alloys are widely used in the aviation and automotive industries. Bearing alloys mainly used in the manufacture of advanced and high-speed engine bearings include silver-lead-indium alloy, lead-cadmium-indium alloy, cadmium-silver-copper-indium, silver-thallium-indium alloy, lead-tin-indium alloy, copper-tin Indium alloy, lead tin antimony arsenic indium alloy.
Ferromagnetic alloy
Ferromagnetic alloys are also called Heusler alloys, and the most widely used are copper-manganese-indium alloys (Cu/Mn/In).
memory alloy
There are also memory alloys indium thallium alloys (In/Tl) and indium cadmium alloys (In/Cd), which belong to the new generation of alloys.
decorative alloy
Decorative alloys, including gold-silver-palladium-copper alloys (Au/Ag/Pd/Cu) used as ornaments, adding indium can improve the hardness and durability of ornaments and increase the color of ornaments. The commonly used Au75/Ag20/In5 alloy is commonly known as "Green Gold".
Other indium alloys
Indium alloys are also used in dentistry and gemstones. Its composition is usually: gold 5-65%/palladium 2-30%/silver 10-15%/copper 10-15%/indium 0.5-5%.
