Abstract
It is found that alloys including amorphous phase comprising at least a first element selected from the group consisting of Pt and Ru, at least a second element selected from the group consisting of Zr, Hf, Si, Ir, Ru, Pd and Ni, and at least a third element selected from the group consisting of Si, Cu, Cr, Fe, Mo, Co, Al, Zr, Hf, Ni and Ru have excellent machining characteristics, heat-resistant characteristics, corrosion resistance and adhesion resistance. Using the alloys as the molding surface of a die, a heat resistant molding die for forming glass optical device having fine structure for performing high definite functions became possible to manufacture with excellent machining characteristics.
