ALUMINUM ALLOY MATERIAL SINGLE LAYER OF WHICH ALLOWS THERMAL BONDING MANUFACTURING METHOD THEREFOR AND ALUMINUM BONDED BODY USING SAID ALUMINUM ALLOY MATERIAL

摘要

Provided is an aluminum alloy material that can be heat-bonded in a single layer without using a bonding member such as a brazing material or a filler material, a method of bonding the same, and an aluminum bonding body using the aluminum material. Si: 1.0 to 5.0 mass%, Fe: 0.01 to 2.0 mass%, consisting of an aluminum alloy composed of residual Al and inevitable impurities, and an Al-based intermetallic compound having a circle equivalent diameter of 0.01 to 0.5 µm. Aluminum alloy material having a heat-bonding function in a single layer, characterized in that ~1×10 ⁴ particles/µm ^{3 are} present, and that there are 200 or less Si-based intermetallic compounds having a circle equivalent diameter of 5.0 to 10µm. And it provides a manufacturing method and an aluminum joint using the same.
