Spiral groove copper sleeve, wear-resistant copper sleeve, environmentally friendly recyclable copper sleeve. Using excellent electrolytic copper as the matrix, zinc ingot is mixed according to the national standard proportion to form wear-resistant copper alloy material. This copper alloy has good mechanical properties，According to the different kinds of alloying elements contained in the material, it can be divided into ordinary brass and special brass. Ordinary brass is made of copper and zinc, which is called ordinary brass. Special brass consists of two or more elements of a variety of alloys called special brass, such as lead, tin, manganese, nickel, iron, silicon and other elements. In the machining of mechanical parts and parts of automation equipment, ordinary brass is usually used instead. Precision machined parts with special requirements also use special brass! Ultimately according to the mechanical equipment parts on the drawing process requirements processing!
