7075 aluminum bar is widely favored by the mechanical processing industry for its high strength and hardness performance. In order to improve the performance of 7075 aluminum bar, it is necessary to hardening 7075 aluminum bar. At present, there are two mainstream processing methods, namely processing strengthening and solid solution strengthening.

7075 aluminum bar strengthened

Hardening in processing enterprises is also known as cold hardening, that is, when 7075 aluminum bar is processed in cold deformation under recrystallization temperature, the internal dislocation density of 7075 aluminum bar increases continuously, the greater the deformation degree, the more serious the dislocation entanglement, the greater the risk of deformation resistance and the higher the strength.The degree of strengthening after cold deformation is affected by deformation degree, temperature and material properties.

Solid solution reinforced 7075 aluminum bar

7075 aluminum bar adds alloy elements to form infinite or finite solid solution, obtaining high strength, excellent plasticity and good machining performance.A finite solid solution can be formed by adding alloying elements to 7075 aluminum bar, and the limited equilibrium solubility can enhance the solid solution.
