Indium is a rare metal, and its distribution in the earth's crust is relatively small and scattered. It has a slightly bluish luster, a very soft texture, strong plasticity, and good ductility, and is widely used in aerospace, radio, and electronics industries, medical, national defense, high-tech, energy, and other fields. In addition to beryllium and several refractory metals, indium can form different types of indium alloys with almost all elements in the periodic table.
Advantages of Indium Alloys
Improve the mechanical properties of the alloy
Indium can be mixed with titanium, molybdenum and other metals to prepare high-strength titanium alloys, high-hardness molybdenum alloys, etc. Because of the indium element contained in these alloys, their strength, stiffness, hardness and other properties are improved, and they also exhibit higher corrosion resistance.
Improve the corrosion resistance of the alloy
Indium is highly resistant to corrosion and can form a dense oxide film on the surface of the metal, thus protecting the metal from corrosion. Therefore, indium occupies an important position in alloys used in high-temperature, high-pressure, strong acid, and strong alkali environments.
Less stress on parts
Less heat in any soldering or brazing application translates to less stress for the components involved. This is due to less thermal expansion during the bonding process.
A usable plastic range
Since there is a gap between the temperatures that these alloys start melting and turn completely liquid, they are especially useful for brazing applications with uneven surfaces where a fully liquid braze may start dripping away from the joint area.
Improved wetting of ferrous alloys
The addition of indium into the Silver-Copper system is known to improve wetting to ferrous metals.
Increased profits
This is due to reduced energy consumption, reduced rework (due to less stress on parts), and reduced field failures.
