Automotive Zinc Plated Surface DIN Plain Weld Screws

Copper alloy Zinc plated surface finish welding screw for Automotive.

Description

Welding screw is also called energy storage screw, electric bolt welding stud, or planting welding nail, etc.

Welding screw is used in a small range, which is only used in the sheet metal industry and the factory producing the case.

Copper alloy is an alloy composed of pure copper and added one or more other elements. Pure copper is purple-red, also known as red copper. Commonly used copper alloys are divided into three categories: brass, bronze, and cupronickel.

Zinc is easy to form a protective film on the surface at room temperature, so the biggest use of zinc is in the galvanizing industry.
Copper zinc plating can form alloys with many non-ferrous metals. Among them, alloys composed of zinc, aluminum and copper are widely used in die castings. A brass composed of zinc, copper, tin, and lead, used in machinery manufacturing. Zinc plates containing a small amount of lead, cadmium and other elements can be made into zinc-manganese dry battery negative electrodes, printed zinc plates, powder-corroded photographic plates and offset printing plates. Zinc can react with acids or strong bases to release hydrogen. Zinc fertilizer (zinc sulfate, zinc chloride) can promote plant cell respiration and carbohydrate metabolism.

Zinc plating can prevent corrosion and provide a zinc protective film for the metal. The conductive metal material repair and color-increasing care agent; the only double protection, synthetic metal resin protective layer and cathodic protective layer, can resist bad weather, suitable The metal is used as an outer layer for long-term protection; it has excellent resistance to corrosion by salt and water.
