PURPOSE: To obtain a clad material for a glasses frame capable of easily securing high bonding strength and excellent corrosion resistance by interposing the first intermediate layer composed of Ta and the second intermediate layer composed of Ni or a Ni alloy between a core material and a surface material in this order from the surface of the core material.
CONSTITUTION: A clad material is constituted by interposing the first intermediate layer 3 composed of Ta and the second intermediate layer 4 composed of Ni or a Ni alloy between a core material 1 composed of Ti or a Ti alloy and a surface material 2 composed of gold or a gold alloy in this order from the surface of the core material 1. The first intermediate layer 3 performs action preventing the deterioration of corrosion resistance after the heating to high temp. and the second intermediate layer 4 shows action improving processability and, therefore, bonding strength and corrosion resistance are not deteriorated by the processing of a glasses frame to respective constitutional parts and the soldering at the time of assembling of the glasses frame and, even after manufacturing, high bonding strength and excellent corrosion resistance are secured.
