Indium is a rare steel, and its distribution in the earth’s crust is relatively small and scattered. It has a barely bluish luster, a very tender texture, robust plasticity, and good ductility, and is extensively utilized in aerospace, radio and electronics industries, medical, national protection, high-tech, energy, and different fields. In addition to beryllium and several other refractory metals, indium can kind various kinds of indium alloys with virtually all components within the periodic desk.
Indium Alloys
A quick Introduction to the Indium Alloy
Indium alloy is generally divided into binary alloys, ternary alloys, and multi-element alloys.
Typically, the melting temperature of indium alloy mainly composed of indium is relatively low, which is primarily used as some low melting point alloys or solders.
While some alloys have very little indium content, indium mainly plays a task of modification, similar to enhancing the energy of non-ferrous metal alloys, bettering their ductility, abrasion resistance, corrosion resistance, and changing the coloration of precious metals.
Classification of the Indium Alloy
Typically, the indium alloy might be divided into 5 categories, which are bearing alloys, ferromagnetic alloys, reminiscence alloys, decorative alloys, dental and gemstone alloys. The following is a quick introduction of the 5 varieties of indium alloy:
1. Bearing Alloy
Bearing alloys are widely used within the aviation and automotive industries. The bearing alloys mainly used within the manufacture of high-pace engine bearings embrace 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.
2. Ferromagnetic Alloy
Ferromagnetic alloys are additionally known as Heusler alloys. The most generally used ferromagnetic alloy is copper manganese indium alloy (Cu / Mn / In).
3. Reminiscence Alloy
Indium thallium alloy (In / Tl) and indium cadmium alloy (In / Cd) are memory alloys, which belong to the new technology of alloys.
4. Decorative Alloy
The addition of indium to the gold-silver-palladium-copper alloy used for ornaments can enhance the hardness and sturdiness of the ornaments and increase the coloration of the ornaments. The generally used Au75 / Ag20 / In5 alloy is often known as "green gold".
5. Dental and Gemstone Alloy
Indium alloy can also be utilized in dentistry and gemstones. Its composition is often: gold 5 to 65% / palladium 2 to 30% / silver 10 to 15% / copper 10 to 15% / indium 0.5 to 5%.
