摘要： The present invention relates to a dental alloy for machining by a CAD/CAM system. In particular, the dental alloy for machining by a CAD/CAM system features a minimum usage of expensive gold and platinum by comprising gold (Au) in an amount of between 0.1% and 5.0% by weight and platinum (Pt) in an amount of between 0% and 5.0% by weight, in addition to palladium (Pd) in an amount of between 30% and 50% by weight, indium (In) in an amount of between 25% and 50% by weight, silver (Ag) in an amount of between 10% and 40% by weight and iridium (Ir) in an amount of between 0.1% and 0.3% by weight. Accordingly, compared with a conventional dental casting alloy composed of gold in an amount of between 40% and 99% the dental alloy for machining by a CAD/CAM system of the invention can be provided at a lower manufacturing cost, while offering processability equivalent to that of zirconia that can be machined by a conventional CAD/CAM system.
