 Marine grade aluminium square tube hardness: Many customers are very concerned when buying aluminum. The hardness can be directly related to the chemical composition of the alloy. Secondly, different conditions also have a greater impact. From the perspective of the high hardness that can be achieved, the 7 series, the 2 series, the 4 series, the 6 series, the 5 series, the 3 series, and the 1 series decrease in order.
Strength is an important factor that must be considered during product design. When it is made of aluminum alloy components as components, the appropriate alloy should be selected according to the pressure it is subjected to. Pure aluminum has low strength, while the 2 series and 7 series heat-treated alloys have a high degree of hardness and strength.
Marine grade aluminium square tube corrosion resistance: corrosion resistance includes chemical corrosion, stress corrosion resistance and other properties. Generally speaking, pure aluminum of series 1 has excellent corrosion resistance, series 5 performs well, followed by series 3 and 6, and series 2 and 7 are poor. The selection principle of corrosion resistance should be determined according to its use occasion. When using high-strength alloys in a corrosive environment, various anti-corrosion composite materials must be used.
