Indium plating

Indium is a soft, rare metal distinguished by its low melting point of 156.6°C and a Mohs hardness of 1.2. These physical characteristics allow it to form uniform electroplated coatings with exceptional adhesion to difficult substrates like glass and metals. Consequently, Indium is a premier choice for hermetic sealing and low-temperature bonding applications where malleability and tight seals are critical. Beyond its sealing capabilities, Indium offers significant functional benefits, including natural lubricity and high wear resistance, making it ideal for sliding bearings. Its chemical stability is equally impressive, providing resistance against sulfur, alkalis, and organic acids. This makes Indium highly effective for anti-tarnish coatings on silver and for protecting components in harsh lubrication environments.
