High strength: The strength of 7 series aluminum alloy is much better than that of mild steel. Its main alloying elements are zinc and magnesium. The MgZn2 structure formed by zinc and magnesium has obvious strengthening effect, making the heat treatment effect of 7 series aluminum plates far better than other aluminum plates. . As the zinc and magnesium content increases, the strength of the aluminum plate will further increase. Especially when the temperature is lower than 150℃, the performance is better.
High mechanical properties: 7 series aluminum alloys have excellent mechanical properties, including high strength, hardness and good plasticity. Due to the small and even distribution of internal crystals, the 7 series aluminum plate has super wear resistance, and its high level of drilling performance is also rare. These properties make it suitable for manufacturing aircraft parts that need to withstand heavy loads and high-speed movements.
