Beschreibung
Zusammenfassung:	This invention provides an aluminum alloy material capable of being thermally bonded in a single layer without using a bonding agent, such as a brazing or welding filler metal. This invention also provides a bonding method for the aluminum alloy material, and an aluminum bonded body using the aluminum alloy material. The aluminum alloy material is made of an aluminum alloy containing Si: 1.0 to 5.0 mass % and Fe: 0.01 to 2.0 mass % with the balance Al and inevitable impurities. The aluminum alloy material contains 10 to 1×104 pieces/μm3 of Al-based intermetallic compounds having equivalent circle diameters of 0.01 to 0.5 μm and 200 pieces/mm2 or less of Si-based intermetallic compounds having equivalent circle diameters of 5.0 to 10 μm.
