PRECIOUS ALLOY FOR PORCELAIN FUSED TO METAL CROWN

摘要

The present invention relates to a precious alloy for porcelain fused to a metal crown of a dental prosthesis, where the precious alloy is a main component, and more specifically, to a precious metal alloy for porcelain fused to a metal crown having material properties similar to those of the existing precious metal alloys for porcelain fused to metal crown while decreasing content of gold (Au), which is an expensive precious metal, and preventing discoloration as well as corrosion. A precious metal alloy for porcelain fused to a metal crown of the present invention is composed of 60.0-79.0 wt% of gold (Au), 3.0-10.0 wt% of platinum (Pt), 1.0-11.0 wt% of palladium (Pd), 1.0-8.0 wt% of copper (Cu), 0.5-8.0 wt% of silver (Ag), 0.1-5 wt% of indium (In), and 0.1-3.0 wt% of tin (Sn).;COPYRIGHT KIPO 2014
