Abstract
Two newly developed brazing alloys suitable for vacuum brazing (VAC) and controlled atmosphere brazing (CAB), Hogal-3571 and Hogal-3572 respectively, will be presented in this paper. Together with high strength after brazing long life corrosion properties in SWAAT were achieved. Hogal-3571 and 3572 will be compared to other high strength alloys that are already delivered by Hoogovens Aluminium, i.e. Hogai-3570 as well as AA6063 and P.A6060. This paper describes the metallurgical development of the two new brazing alloys. The chemical compositions, the strengthening mechanism, the strength as a function of the cooling rate and the TTP-diagram of the Hogal-3571 alloy will be discussed.
