Anodized Aluminum technology is the technology of oxidizing aluminum products by immersing the product in an anodized tank. In which aluminum products are installed as the anodes, the chemicals are the cathode.
Black Oxide is a technology that creates an oxide film covering the entire surface of steel metal products to make the surface more beautiful and prevent rust for the product.
Multi-layer plating increases corrosion resistance in demanding working environments, increases the adhesion of the coating, increases electrical conductivity.
Tin plating is the process of coating a metal surface with a thin layer of tin. Tin plating on the metal surface makes the metal more durable and prevents rust during use or increases the electrical conductivity of the product.
