Copper plate is a high-purity copper alloy plate, the main components of which are copper and tin, usually containing more than 90% copper and a small amount of tin. It has excellent thermal and electrical conductivity, strong corrosion resistance, good mechanical properties, etc., so it is widely used in electronics, aerospace, chemical industry, mechanical equipment and other fields.

Brass plate is a widely used lead brass with good mechanical properties and good cutting processability. It can withstand cold and hot pressure processing and is used for various structural parts such as gaskets and bushings that are processed by cutting and stamping. Tin brass plate has high corrosion resistance and good mechanical properties. It has good pressure processing properties in cold and hot states and can be used for corrosion-resistant parts on ships and parts and conduits that come into contact with media such as steam and oil.
