7 series aluminium sheet is a super hard aluminium alloy series, which is preferred as a material for aerospace equipment. Series 7 aluminium is a series of super-hard aluminium alloys. The main alloying elements are zinc, magnesium and copper. 7 series aluminium sheets are represented by grades including 7050 and 7075, which are particularly good in heat treatment and are extremely strong deformed aluminium alloy sheets. They have good plasticity after solidification treatment and have good mechanical properties, wear resistance and fatigue resistance. The disadvantages are poor welding properties, a tendency to stress corrosion cracking, and the need for aluminum cladding or other protective treatment. 7 series aluminium sheet is mainly used in aerospace equipment as the material of choice, but also widely used in a variety of machinery, moulds and other processing and production fields.
The main alloying element of 7050 aluminium sheet is zinc. The addition of magnesium to an alloy containing 3%-75% zinc results in the formation of MgZn2, which has a significant strengthening effect, making the alloy far superior to aluminium-zinc binary alloys in terms of heat treatment. It is used in aircraft manufacturing structures and other highly stressed structural bodies requiring high strength and corrosion resistance. More specifically, 7050 aluminium sheet is commonly used in aerospace, mould processing, mechanical equipment, fixtures and jigs; especially for aircraft manufacturing structures and other highly stressed structural bodies requiring high strength and corrosion resistance.
7075 aluminum sheet belongs to super hard aluminum, is a cold treatment forging alloy, high strength, high hardness, far better than soft steel. 7075 aluminum sheet is used in aerospace industry, blow molding (bottle) mold, ultrasonic plastic welding mold, golf head, shoe mold, paper plastic mold, foam molding mold, waxing mold, paradigm, jig, mechanical equipment, mold processing, making high-end aluminum alloy bicycle frame and other fields.
