Aluminum bonding alloy, and clad material and aluminum bonding composite material each having bonding alloy layer made of the alloy

摘要

An aluminum bonding alloy 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. A clad material includes a non-aluminum metal layer made of the non-aluminum metal and a bonding alloy layer made of the aluminum bonding alloy. The non-aluminum metal layer and the bonding alloy layer are bonded together by pressure welding and diffusion bonding.

主权项

1. A clad material comprising:
a non-aluminum metal layer made of any one non-aluminum metal selected from steel, copper, nickel, and titanium; a bonding alloy layer made of an aluminum bonding alloy consisting essentially of 0.08 mass % or more and 0.90 mass % or less of Mg, and the balance of Ni; and an aluminum layer made of pure aluminum or an aluminum alloy made of an Al—Mn-based alloy or Al—Mg-based alloy comprising 90 mass % or more of Al, wherein the non-aluminum metal layer, the bonding alloy layer, and the aluminum layer are pressured-welded and diffusion-bonded to each other in this order so as to be bonded together.
