Abstract

The invention belongs to the technical field of aluminum alloy processing, and relates to a 6082S aluminum alloy sheet for stamping and a processing technology thereof. The 6082S aluminum alloy sheetis prepared from the following elements of, in percentage by weight, 0.9-1.2% of Si, 0.1-0.25% of Fe, less than or equal to 0.1% of Cu, 0. 5-0.6% of Mn, 0.8-1.1% of Mg, less than or equal to 0.1%of Cr, less than or equal to 0.1% of Zn, 0.01-0.02% of Ti, less than or equal to 0.05% of a single impurity, less than or equal to 0.15% of total impurities, and the balance Al. The defect that the existing 6082 aluminum alloy is wide in range is solved, due to the existence of Fe and Mn elements in the alloy, micron-scale AlFeSi, AlMnSiFe and Al6Mn phases are often separated out in the solidificationprocess, the coarse one-time solidification phases is hard and brittle, is difficult to dissolve in an aluminum matrix in subsequent homogenization and solid solution treatment, in the stamping process, a crack source can be easily formed, so that stamping cracking is caused; by controlling the component range of 6082 aluminum alloy, a thin plate with good stamping performance is obtained.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy processing, and relates to a 6082S aluminum alloy sheet for stamping and a processing technology thereof. Background technique [0002] 6xxx series alloys are the most important press-worked alloys in wrought aluminum alloys. They are aluminum alloys with magnesium and silicon as the main alloying elements. The main strengthening phase is the intermetallic compound Mg formed by magnesium and silicon. 2 Si is an aluminum alloy that can be strengthened by heat treatment. 6xxx series alloys have medium strength, good plasticity, excellent weldability and corrosion resistance, and no tendency to stress corrosion cracking. Therefore, 6xxx series alloys are the most widely used aluminum alloys in the world. 6082 aluminum alloy is the main alloy member in 6xxx alloy, 6082 alloy usually has good processing characteristics and excellent bending performance. In O state and T4 state, it has good be...
