Description

Taking into account the antibacterial property, safety, mechanical and corrosion resistance property, Copper (Cu) as the main antibacterial element, was dissolved into the stainless steel matrix through special smelting process which was then precipitated out of supersaturated matrix using specific heat treatment process as Cu-rich phase. When copper bearing stainless steel contacts with moist air or corrosive medium, the uniformly distributed copper rich phase releases copper ions to induce excellent antibacterial effect. The copper ions can effectively inhibit the formation of bacterial biofilm by destroying the bacterial cell membrane, cell walls and their enzyme systems to prevent bacterial infection.
