Dental cobalt-chromium-molybdenum-copper antibacterial baked porcelain alloy and application thereof

The purpose of the invention is to provide a dental cobalt-chromium-molybdenum-copper antibacterial baked porcelain alloy which is mainly used for crowns, bridges and the like of baked porcelain teeth. The dental cobalt-chromium-molybdenum-copper antibacterial baked porcelain alloy comprises the following specific chemical components (wt%): less than or equal to 0.08% of C, 16-26% of Cr, 4-10% of Mo, 0.5-2% of W, 0.1-0.5% of Re, less than or equal to 0.1% of Ni, 1-6% of Cu and the balance of Co, wherein RE is a rare earth element. The cobalt-based baked porcelain alloy provided by the invention is added with appropriate copper element and rich copper precipitated phase is evenly dispersed and distributed through special heat treatment so that the alloy is enabled to have broad-spectrum antibacterialfunction. The alloy provided by the invention contains no toxic element and has excellent resistance to oxidation and corrosion, and can be well matched with the existing porcelain powder in use.
