<p>PURPOSE:To obtain the combined material having high joint strength and excellent formability, workability, durability, etc., by specifying the compsn. of a metallic plate and metallic net and forming the structure of the metallic net into an expanded net. CONSTITUTION:The alloy having the compsn. range constituting of 10 to 25wt.% Au, 15 to 35wt.% Pd, 45 to 70wt.% Ag, and further added with 0.1 to 5wt.% 1 or 2 kinds of Sn and In is made into an alloy plate having 0.05 to 0.5mm thickness. The expanded net 1 consisting of the alloy having the above- mentioned compsn. range is superposed on one surface of this alloy plate and is hot joined thereto at >=600 deg.C, by which the alloy plate and the expanded net are metallurgically integrated. The combined material having the high joint strength is obtd. in this way and the material having the excellent characteristics as the dental material in terms of the formability, workability, durability, supporting strength, etc., is obtd.</p> |
