Technical Introduction: "Heat Treatment of Aluminum Alloys"
From large products to small items, we accommodate a variety of products!
Aluminum alloys are strengthened by heat treatment processes. Below are some representative treatments. 1. Solution Treatment and Natural Aging (T-4) This heat treatment involves rapidly cooling (water cooling) the aluminum alloy while maintaining a state where magnesium (Mg), copper (Cu), silicon (Si), and other elements are dissolved in the aluminum base (supersaturated solid solution). 2. Solution Treatment and Artificial Aging (T-6) This treatment improves hardness and mechanical strength by precipitating compounds of magnesium (Mg), copper (Cu), silicon (Si), etc., that were dissolved during the solution treatment, and is accelerated by raising the temperature to a certain level. 3. Stabilization Treatment (T-5) For some aluminum parts, to prevent changes in properties due to temperature rise during use, this process stabilizes the characteristics of the parts at a temperature slightly higher than the operating temperature. 4. Annealing Treatment (O Treatment) Annealing may be performed at around 350°C to improve workability. This is done when reprocessing parts that have already undergone T-6 treatment, particularly to reduce deformation in parts that are likely to deform. ● For more details, please contact us.
