    In all metals, silver antibacterial ability is strongest, about 100 times of copper.

    Have more broad antibacterial spectrum, can kill more types of pathogenic bacteria.

    Add less than one over ten of copper, stainless steel has a little influence on the performance of the original level.

    Silver and iron is immiscible element of a typical system, almost no solubility in liquid or solid state

    Existing casting process is easy to produce silver element segregation, the improvement of heat treatment process is very limited

    Antibacterial performance is not stable, the high energy consumption of the heat treatment process, the effect is not obvious, it is difficult to use in the industrial production

    Through the silver compound is added to the raw materials, the compound decomposition in the process of sintering formed dispersed silver particles

    Excellent antibacterial properties, antibacterial above 99%

    Stable antibacterial ability, silver particle dispersed evenly

    Have permanent antibacterial ability, does not fear the scrapes and cuts

Antibacterial test results

The Ag - Fe phase diagram shows that Ag - Fe is insoluble in solid state and does not form intermetallic compoundsimage.png

    Use of powder injection molding, can't solve the silver iron miscibility engineering problem

    The nanosize silver particles were distributed evenly in the stainless steel substrate, produce good antibacterial performance

    Only add trace silver, will not affect the performance of stainless steel, not significantly increase the cost of stainless steel

    Can manufacture different type of antibacterial stainless steel
