Indium Plating
Key Features…
LOW MELTING POINT Ideal for low-temperature bonding materials and metal seals UNIFORM COATING Provides consistent surface properties on metal surfaces CHEMICAL STABILITY Excellent resistance to organic acids in lubrication oil TARNISH RESISTANCE Valuable for anti-tarnish coatings on silver plating WEAR RESISTANCE & LUBRICITY Suitable for sliding bearings
Electronics Serves in soldering and conductive coatings of connectors and gaskets, forming strong bonds and ensuring reliable electrical conductivity. Battery Improves performance and lifespan through enhanced conductivity and corrosion resistance. Aerospace Surfaces that require high vacuum integrity, such as those in satellite systems, are often plated with Indium to create effective seals. Automotive Applied on bearings to enhance durability, corrosion resistance, and electrical conductivity. Medical Its low melting point and pliability make it ideal for metal seals in medical equipment.
