Anti COVID-19 Stainless Steel

The invention made it possible to combat both bacteria and virus including COVID-19 and SARS-Cov-2 virus

• The fabrication of present invention is based on the mixed powder of Copper
• Excellent broad-spectrum anti-bacteria and anti-virus properties, including H1N1 and Covid19 virus
• Antibacterial Cu-bearing stainless steel (SS) must control its Copper content to an acceptable value to make sure that it can be processed while still has antibacterial property

• Excellent broad-spectrum anti-bacteria and anti-virus properties, including H1N1 and Covid19 virus (inactivation rate >99.99%)
• Intact of the stainless-steel property, the mechanical, corrosion resistance, and processability properties are comparable to 200 series stainless steel in the market
• Good long-term antibacterial and abrasion resistance, even though when the steel surface is scratched or rubbed away
• Producible at large scale by existing steel powder metallurgy process

• International Exhibition of Inventions of Geneva 2022 - Silver

• Lift buttons, door bells, PA controls and items that are frequently touched by people in hospitals or other public areas.
• Medical tools like tweezes and knives.
• Kitchenware, like cookware, knives, stoves, cups and dishes.
• Other consumer products like electric appliance cases, watch cases, water taps, etc.
