First, the product introduction
Weite Tin Bar products are made of high-purity raw tin, refined by international advanced manufacturing methods and under strict process control. They are fully compliant with IPC and national standards, and various metal alloy components can be produced.

Second, product features
· Add a sufficient amount of antioxidant elements, strong anti-oxidation ability and less tin slag.
· Less metal impurities and low oxide content, less corrosive to tin cylinders;
· After melting, the tin liquid surface is smooth and flat, with low viscosity and excellent fluidity.
