Aluminum brazing material for use in aluminum heat exchanger |
摘要 |
Aluminum brazing alloys for assembling aluminum heat exchangers by brazing which consist essentially of 4.5 to 13.5% of Si, from 0.005% to less than 0.1% of Sr and the balance essentially Al and, further, optionally may contain at least one element selected from the group consisting of 0.3 to 3.0% of Mg, 2.3 t0 4.7% of Cu and 9.3 to 10.7% of Zn. The aluminum brazing alloys provide high strength brazed joints with highly refined microstructure and brazing operation can be performed in a good condition without causing any detrimental cavity. Such excellent properties make the brazing alloys especially suited for the fabrication of superhigh pressure heat exchangers.
