Indium alloys offer a spectrum of possibilities, ranging from binary to ternary and multicomponent compositions. As the primary constituent, indium lends these alloys relatively low melting points, making them ideal for applications such as low-melting-point alloys or solders. Beyond mere utility, indium’s presence in some alloys serves to enhance properties like strength, ductility, wear resistance, and corrosion resistance, or even to alter the appearance of precious metals.
Indium Alloy Varieties:
- Bearing Alloys: Widely employed in aviation and automotive industries, bearing alloys play a crucial role in high-end engine bearings. Variants include silver-lead-indium, lead-cadmium-indium, cadmium-silver-copper-indium, silver-thallium-indium, lead-tin-indium, and copper-tin alloys, along with the indium-infused lead-tin-antimony-arsenic alloy.
- Ferromagnetic Alloys: Commonly referred to as Heusler alloys, the copper-manganese-indium alloy (Cu/Mn/In) reigns supreme in this category.
- Memory Alloys: Representing the cutting edge, memory alloys like indium-thallium (In/Tl) and indium-cadmium (In/Cd) are part of the new generation of alloys.
- Decorative Alloys: Elevate the aesthetics of ornaments by incorporating indium into gold, silver, palladium, and copper alloys (Au/Ag/Pd/Cu). This addition enhances their hardness, durability, and coloration. The renowned “Green Gold,” comprising Au75/Ag20/In5, is a prime example.
- Other Indium Alloys: From dentistry to gemstones, indium alloys find application across diverse fields. Typically comprising gold, palladium, silver, copper, and indium in varying proportions, these alloys cater to specific requirements.
- Liquid Alloys: The fusion of indium with gallium, tin, zinc, or other metals produces room temperature liquid metals with melting points ranging from 6°C to 30°C. These alloys, including gallium indium tin alloy, possess attributes such as low melting points, high boiling points, excellent thermal and electrical conductivity, and environmental friendliness.
