1. What is annealing treatment? The process of heating Aluminum Die Casting Parts to usually around 300°C, holding it for a period of time, and cooling to room temperature with the furnace is called annealing. During annealing, the solid solution will decompose and the particles of the second phase will aggregate, which can remove the internal stress of Aluminum Die Casting Parts, keep the dimensions of Aluminum Die Casting Parts stable, avoid deformation, and enhance the plasticity of Aluminum Die Casting Parts.
2. What is solution treatment? Heat the Aluminum Die Casting Parts to almost the melting point of the eutectic, and then keep it at this temperature for a longer time, and then quickly cool down so that the strengthening components can be dissolved well, and keep this high temperature state until room temperature. This process is called Solution treatment. Solution treatment can enhance the strength and plasticity of Aluminum Die Casting Parts and improve the corrosion resistance of the alloy. The effect of solution treatment is usually related to three aspects: solution treatment temperature, solution treatment holding time, and cooling rate.
3. What is aging treatment? The solution treatment of Aluminum Die Casting Parts is heated to the set temperature, after a period of time, it is out of the furnace, and the method of slowly cooling in the air is called aging. If the aging strengthening is completed at room temperature, it is called natural aging, and if the aging strengthening is completed in an environment higher than room temperature and holding for a period of time, it is called artificial aging. Aging treatment undergoes a spontaneous process of decomposition of supersaturated solid solution, which can restore the lattice of Aluminum Die Casting Parts to a relatively stable state.
