aluminum alloy based material with single bond thermal bonding function, method for its manufacture and aluminum alloyed body using aluminum alloy based material

摘要

Summary "aluminum alloy based material with single bond thermal bonding function, method for its manufacture and aluminum alloyed body using aluminum alloy based material" The invention provides an aluminum alloy based material aluminum capable of being thermally bonded in a single layer without the use of a bonding agent, such as a filler metal for brazing or welding. This invention also provides a bonding method for the aluminum alloy material and an aluminum alloy body using the aluminum alloy material. The aluminum alloy based material is made of an aluminum alloy containing itself: 1.0 to 5.0 wt% and fe: 0.01 to 2.0 wt% with equilibrium al and unavoidable impurities. The aluminum alloy based material contains 10 to 1 x 104 parts / µm3 of al-based intermetallic compounds with equivalent circular diameters of 0.01 to 0.5 µm and 200 parts / mm2 or less of aluminum-based intermetallic compounds. si with equivalent circular diameters of 5.0 to 10 µm.
