Description

As a part of the 3A group of chemical elements, Indium has similar properties to gallium, namely, it is very soft and ductile, and has a low melting point, making it a liquid in a wide range of temperatures. Its alloys can have custom tailored melting points making this metal useful in the construction of thermal fuses. Indium coatings are used to enhance lubrication in high-speed bearings and to produce mirrors with better reflectivity than aluminium, similar to silver but with better tarnish resistance.

This material data has been provided by Matmatch.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
