Tin Coated/Plated Copper Strip (Copper Strip Tin Coated) for Can Packaging

    Base material thickness: 0.1mm - 0.8 mm

     

    Reflow Tin Plating: Sn 0.8μm - 2.0μm

     

    Base Material: Brass /Bronze /Copper /Lead Frame

Copper strips are tin plated and reflow-processed to improve their properties such as solderability, electric connectivity, and corrosion resistivity. These are highly reliable materials that were reflow processed after being tin-plated to prevent the generation of tin whiskers, which used to be a weakness of tin plating. Their press workability does not change after tin plating and they can be formed into complicated product shapes.
