6063 anodized aluminum bar stock supplier

6063 anodised aluminum bar belongs to aluminum-magnesium-silicon series heat-treatment-reinforced aluminum alloy. In the ternary system composed of AL-Mg-Si, there is no ternary compound, only two binary compounds Mg2Si and Mg2Al3. ) -Mg2Si pseudo-binary cross section is the boundary, forming two ternary systems, α (Al) -Mg2Si- (Si) and α (Al) -Mg2Si-Mg2Al3. In Al-Mg-Si series alloys, the main strengthening phase is Mg2Si, when the alloy is quenched, the more Mg2Si dissolved in the matrix, the higher the strength of the alloy after aging, and vice versa, the lower, the α (Al) -Mg2Si pseudo binary phase diagram, the eutectic temperature is At 595 ° C, the large solubility of Mg2Si is 1.85% and 1.05% at 500 ° C. It can be seen that the temperature has a great influence on the solid solubility of Mg2Si in Al. The higher the quenching temperature, the higher the strength after aging. The higher, on the contrary, the lower the quenching temperature, the lower the strength after aging. Some aluminum profile factories produce qualified profiles, but the strength does not meet the requirements. The reason is that the heating temperature of the aluminum alloy is insufficient or the external heat and internal cooling cause the quenching temperature of the profile is too low.
