Novel cobalt-based baked porcelain alloy and application thereof

The invention provides a novel cobalt-based baked porcelain alloy which comprises the following chemical components in percentage by weight: no more than 0.08% of C, 16-24% of Cr, 10-20% of Fe, 5-15% of Mn, 2-8% of Mo, 2-8% of W, 1-3% of Cu, no more than 0.4% of N, no more than 0.1% of Ni, less than 0.01% of S, less than 0.02% of P and the balance of Co. According to the invention, iron, manganese, tungsten and other elements are added to replace part of expensive element cobalt; the thermal expansion coefficient of the baked porcelain alloy is regulated by regulating the tungsten content, so that the baked porcelain alloy has excellent metal-porcelain binding force; the mechanical property and the corrosion resistance of the baked porcelain alloy are further optimized by the element nitrogen; and meanwhile, the element copper can be dispersed and dissolved out through special thermal treatment, so that the alloy has certain antimicrobial function. Thus, the alloy has great advantaged when being used as a den
