Abstract:
Method of manufacturing a metal vehicle wheel (10) comprising at least a circumferential rim and a disc, comprising a hot stamping step of hot stamping a metal blank into a wheel part (12) having a circumferential rim portion (16) and an integral disc portion (14) and a quenching step of quenching the hot stamped wheel part; and providing at least one other wheel part (20); and a welding step of at least partially circumferentially welding the wheel parts (12, 20) together.
Abstract:
The invention relates to a brazing sheet material for CAB brazing without applying flux, the brazing sheet material comprising of an aluminium core alloy layer provided with a first brazing clad layer material on one or both sides of said aluminium core layer and at least one second brazing clad layer material positioned between the aluminium core alloy layer and the first braze clad layer material, wherein the second brazing clad layer material is an Al-Si alloy brazing material having 5% to 20% Si and 0.01 % to 3% Mg, and wherein the first brazing clad layer material is an Al-Si alloy brazing material having 2% to 14% Si and less than 0.4% Mg. The invention further relates to a brazed assembly manufactured in a brazing operation.
