Abstract
PURPOSE: To obtain a Pt alloy for accessories with high mechanical strength, especially hardness, high fluidity and enhanced castability by adding a predetermined percentage each of B or Ca boride and one or more among Pd, Ir, Ru, Rh, Au, Ag, etc. to Pt.
CONSTITUTION: This Pt alloy for accessories is obtd. by adding 0.01W3 w/o B or Ca boride and 1W15w/o one or more among Pd, Ir, Ru, Rh, Au, Ag, Cu, Ni and Co to 80W95w/o Pt. By especially adding B or Ca boride, the alloy grains are prevented from being coarsened at high temp. in soldering or other process to maintain the mechanical strength. This alloy has high fluidity in casting and can well reproduce the fine pattern of dies. Especially, it generates very few blow holes and has superior castability.
