6082 aluminium strip is one of the alloy models of the 6-series (aluminium – magnesium – silicon) aluminum alloy. Usually, 1 series, 3 series, and 5 series are non-heat treatable alloys, while 2 series, 6 series, and 7 series are heat treatable alloys, and 4 series are partially heat treatable and partially non-heat treatable.
6082 Aluminium strip
6082 aluminum alloy can usually be heat treated for higher strength, but relatively low ductility.
The strength, welding performance, and corrosion resistance of the 6082 aluminum strip are very excellent, and it is mainly used in the transportation industry and the structural engineering industry.

The 6082 alloy aluminum strip is characterized by containing the refractory metal Mn. The melting temperature should be controlled at 740-760℃. Stir evenly more than two times before sampling to ensure that the metal is completely melted, the temperature is accurate, and the composition is uniform.
After stirring, take a sample from the middle of the molten aluminum depth and from the left and right sides of the furnace for analysis. After passing the test, the converter can be converted.
Smelting process of 6082 aluminum strip
After the melt is transferred to a static furnace, powder spraying and jet refining are carried out with nitrogen and refining agent, refining temperature is 735-745 ℃, the time is 15 minutes, and static refining is 30 minutes after refining. Through this process, the melt is degassed, deslagged, and cleaned.
During the smelting and casting process, there are two filter devices between the mold and the furnace mouth, which are filtered by the foam ceramic filter plate (30PPI) at the furnace mouth. Before pouring, filter oxides and slag inclusions in the melt with a 14-mesh glass fiber cloth.
Smelting process of 6082 aluminum strip
6082 alloy has a higher casting temperature (compared to the 6063 normal processes), lower casting speed, and higher water flow. The above process should be strictly controlled and cannot exceed the scope, otherwise, it will easily lead to casting failure.
T6: Solution treatment + artificial aging. Users who have relatively low requirements for dimensional stability and elastic allowance accuracy can choose this tempering state.
T651: Solution Treatment + Tensile Stress Relief + Artificial Aging. T651 is usually used for precision workpieces to avoid elastic recovery after machining to maintain dimensional stability.
Compared with T6 tempering, the internal stress of T651 tempering will be smaller, and it is not easy to deform during processing.
