Introduction of heat treating aluminum 6061
Heat treatment refers to a metal processing technology, specifically, a solid material, through the means of heating, heat preservation and cooling, to obtain the expected structure and performance. 6061 aluminum alloy is a medium-strength aluminum alloy, which can be strengthened by heat treatment. Its quenching sensitivity is poor (the quenching temperature range is wide and the quenching critical speed is low), so it is easier to achieve quenching heat treatment (it can be quenched by a quenching furnace or quenched in the extrusion process). This article will discuss the characteristics of heat treating aluminum 6061 in detail.
Is it possible to heat treating aluminum 6061?
If it is heat treatment of aluminum materials, we usually think that 1, 3, 5, 8 series aluminum alloys are non-heat-treatable alloys; 2, 6, 7 series alloys are heat-treatable alloys. Of course, with different materials, the specific heat treatment process performed is also different, and the goals achieved are also different. Such heat treatments as stress relief annealing, recrystallization annealing, homogenization annealing, etc., can be performed on all metal materials. Of course, some metal materials can be strengthened by heat treatment, that is, the strength can be improved by heat treatment, but some cannot. However, this does not mean that heat treatment cannot be performed, it is just that it cannot be strengthened by heat treatment, and it cannot be said that heat treatment cannot be performed.
Heat treating aluminum 6061 type
Can be T4, T6 heat treatment:6061-t4 vs t6
T4 The natural aging to a basically stable state after solution heat treatment is suitable for products that are no longer cold worked after solution heat treatment (straightening and leveling can be carried out, but the mechanical properties are not affected).
T6 The state of artificial aging after solution heat treatment is suitable for products that are no longer cold worked after solution heat treatment (straightening and leveling are possible, but the mechanical properties will not be affected).
The role of heat treating aluminum 6061
A improves hardness
B Reduce the hardness to facilitate cutting or other cutting processing
C eliminates the internal stress caused by various processing.
D Improve the internal organization and properties of the metal to meet different requirements. E Improve surface wear resistance and corrosion resistance.
The object of thermal processing is semi-finished products. When errors occur, waste products will be produced and large losses will occur.
We have professional technicians and business personnel. If you have any questions about heat treating aluminum 6061, you can contact us at any time. In addition, we have a production range for 6061 aluminum plates. It can produce ultra-wide and ultra-thick 6061 aluminum plates, which can eliminate internal stress and will not deform during cutting. The width is within 2650mm and the thickness is within 500mm. Domestic manufacturers that can produce ultra-wide and ultra-thick aluminum plates are rare, and we are one of them.
