Indium Corporation is the world’s premier supplier of pure tin and tin alloys and compounds.

Features & Benefits

High-Purity Tin (Sn)

With a melting point of 505.08 K (231.93°C or 449.47°F) as well as its corrosion-resistant nature, tin is becoming increasingly popular for a number of new and innovative applications, including aerospace and semiconductor.

When reliability counts, don’t settle for lower levels of tin purity that can lead to failure. Indium Corporation sources our tin directly and can ensure its purity in a number of physical forms and levels of up to 99.999%-pure (5N).

Indium Corporation sets the standard, from the mine to product packaging, for the processing of commercial and high-purity indium, germanium, gallium, and tin metals. Quality is assured because we control the production process from the very first step.
