Beklædningsmateriale med et af en nikkel-magnesium-legering dannet bindelegeringslag

摘要

Provided is an aluminum bonding alloy excellent in pressure weldability, diffusion bondability and brazability not only to non-aluminum metals such as steel, copper, nickel and titanium but also to aluminum. Another provided are a clad material and an aluminum bonding composite material each having a bonding alloy layer made of the bonding alloy. The aluminum bonding alloy of the present invention is an Ni-Mg alloy for bonding aluminum and a non-aluminum metal selected from steel, copper, nickel or titanium. The Ni-Mg alloy consists essentially of 0.08 - 0.90 mass% Mg, and the balance of Ni and inevitable impurities. The clad material includes a non-aluminum metal layer (2) made of the non-aluminum metal and a bonding alloy layer (1) made of the aluminum bonding alloy. The non-aluminum metal layer (2) and the bonding alloy layer (1) are bonded together by pressure welding and diffusion bonding.
