Anti Oxidizing Width 600mm Single Side Tin Plated Copper Foil
Anti Oxidizing Width 600mm Single Side Tin Plated Copper Foil
1. Description
Copper product is easy to oxidation when expose in the air and form verdigris. Verdigris can cause large resistance, poor conductivity and power transmission loss. Tin plated copper product due to tin itself characteristics can form stannic oxide thin films to prevent further oxidation. Tin can also form a similar film in halogens so that the tin plated copper product has well corrosion resistance and weldability. At the same time, tin plated copper product has a certain degree of strength and hardness. So it is widely used in electrical and electronic industry product.
Due to the non-toxic and tasteless of tin, tin product is widely used in the food industry, too.
