摘要:
A method of forming a part from sheet metal alloy is provided, for example, forming a part from aluminium alloy. The method comprises heating (A) the sheet metal alloy to a temperature at which solution heat treatment of the alloy occurs and so as to achieve solution heat treatment. The sheet is cooled (B) at least the critical cooling rate for the alloy and then placed between dies to form (C) it into or towards the part.

Extrudeable Al-Mg-Si aluminium alloy with improved strength, corrosion resistance, crush properties and temperature stability, in particular useful in or close to the front part of vehicles. The composition of the alloy is defined within the following coordinate points of an Mg-Si diagram: a1 -a2-a3-a4, where in wt% a1=0.60 Mg, 0.65Si, a2=0.90Mg, 1.0Si, a3=1.05Mg,0.75Si and a4=0.70Mg, 0.50Si and where the alloy has a non-recrystallised grain structure in the extruded profile containing in addition the following alloy components in wt%: Fe up to 0.30 Cu 0.1 -0.4 Mn 0.4-1.0 Cr up to 0.25 Zr up to 0.25 and Ti 0.005-0.15 incidental impurities up to 0.1 each and including Zn up to 0.5 with balance Al.
摘要:
An automobile component including an aluminum alloy product having a base aluminum alloy layer and a first additional aluminum alloy layer disposed directly on the base layer. The base aluminum alloy layer includes 2.0 to 22 wt. % zinc and the zinc is a predominate alloying element of the base layer other than aluminum and the first additional aluminum alloy layer includes 0.20 to 8.0 wt. % magnesium and the magnesium is a predominate alloying element of the first additional aluminum alloy layer other than aluminum. The automobile component may include outer panel sections, high form inner sections, reinforcement sections, crash sections, large flat panel sections, and high strength sections and, when tested in a static axial crush test, a peak load of the automobile component increases at least 20% when compared to alloy 6014 in the T6 temper.
