2A12 aluminum plate heat treatment is to choose a heat treatment specification, control the heating rate up to a corresponding temperature for a certain time and a certain rate of cooling, change the structure of the alloy, the main purpose is to improve the mechanical properties of the alloy, enhance corrosion resistance, improve the processing energy, to obtain dimensional stability.

In order to obtain good aging strengthening effect, 2A12 aluminum plate under the condition of no overheating, overburning and grain growth, the quenching heating temperature is higher, the holding time is longer, is conducive to obtain the maximum supersaturation of uniform solid solution.In addition, the second phase is not precipitated in the quenching cooling process, otherwise in the subsequent aging heat treatment, the precipitated phase will play the role of crystal nucleus, resulting in local uneven precipitation and reducing the aging strengthening effect.Aging temperature at different aging temperature, the influence of precipitated phase of critical nucleus size, number, composition, grew up and gathered speed is different, if the temperature is too low, due to the diffusion is difficult, g. P area is not easy to form, strength, hardness, low after aging, when the aging temperature is too high, spread easily, supersaturated solid solution precipitation phase in the critical nucleus size is big,Over-aging occurs when the strength and hardness are too low after aging.Therefore, all kinds of alloys have the most suitable aging temperature.

The above is about the heat treatment process of 2A12 aluminum plate. If you want to know the price of 2A12 aluminum plate, you can consult us.
