Your Metal Finishing Solution

Tin Plating

AST provides a Bright Acid Tin plating compliant to MIL-T-10727, Type I and ASTM B 545. Our tin plating processes facilitate soldering and improve anti-galling properties in steel, brass, copper, plus numerous other substrates, which otherwise have poor solderability. Tin plating exhibits excellent corrosion resistance and conductivity in a variety of electrical as well as electronic components.
