6061 aluminum alloy is a high-quality aluminum alloy product produced through heat treatment and pre stretching process.
The main alloying elements of 6061 aluminum alloy are magnesium and silicon, forming Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the harmful effects of iron; Sometimes a small amount of copper or zinc is added to improve the strength of the alloy without significantly reducing its corrosion resistance; There is also a small amount of copper in conductive materials to offset the adverse effects of titanium and iron on conductivity; Zirconium or titanium can refine grain size and control recrystallization structure; To improve machinability, lead and bismuth can be added. Mg2Si solid solution in aluminum gives the alloy artificial age hardening function.
Aluminum alloy basic state code:
The F free processing state is applicable to products with special requirements for work hardening and heat treatment conditions during the forming process. The mechanical properties of products in this state are not specified (uncommon)
The annealed state is suitable for processed products that have undergone complete annealing to obtain the lowest strength (occasionally occurring)
The H work hardening state is suitable for products that improve strength through work hardening. After work hardening, the product can undergo (or not undergo) additional heat treatment to reduce strength (usually non heat treated strengthening materials)
The W solid solution heat treatment state is an unstable state that only applies to alloys that have undergone solid solution heat treatment and are naturally aged at room temperature. This state code only indicates that the product is in the natural aging stage (uncommon)
The T heat treatment state (different from the F, O, H state) is suitable for products that have undergone (or have not undergone) work hardening to achieve stability after heat treatment. The T code must be followed by one or more Arabic numerals (usually for heat treated reinforced materials). The common state code for non heat treated reinforced aluminum alloys is usually the letter H followed by two digits.
