Now the most common pump is made of stainless steel, mainly because stainless steel has the advantages of strong oxidation resistance, long service life, resistance to rust, corrosion resistance, resistance to deformation, lead-free safety, high hardness, wear resistance, etc., and it is durable. It is widely used in various balls, bicycles, motorcycles, etc.
