7000 aluminum refers to aluminum alloy with grade 7, commonly known as superhard aluminum (superhard aluminum alloy)

Superhard aluminum alloys are aluminum, zinc, copper and magnesium alloys. This alloy has the highest strength at room temperature. After solution treatment and aging, its strength reaches 680MPa, and its specific strength is equivalent to ultra-high strength steel, so it is named ultra-hard aluminum.

The types of superhard aluminum alloys are:

7005

Extruded materials are used to manufacture welded structures with high strength and fracture toughness, such as trusses, bars and containers of transport vehicles; Large heat exchangers, and parts that cannot be solid-solution treated after welding; It can also be used to make sports equipment, such as tennis rackets and softball bats.

7039

Frozen container, cryogenic instrument and storage box, fire-fighting pressure equipment, military equipment, armor plate, missile device.

7049

Used for forging parts with the same static strength and high stress corrosion cracking resistance as 7079-T6 alloy, such as aircraft and missile parts-landing gear hydraulic cylinder and extrusion parts. The fatigue performance of the parts is almost the same as that of 7075-T6 alloy, but the toughness is slightly higher.

7050

Plates, extrusions, free forgings and die forgings of aircraft structural parts. The requirements of alloy for manufacturing this part are: high spalling corrosion resistance, stress corrosion cracking ability, fracture toughness and fatigue resistance.

7072

Air conditioning aluminum foil and ultra-thin strip; Cladding of 22 19, 3003, 3004, 5050, 5052, 5 154, 606 1, 7075, 7475, 7 178 alloy plates and tubes.

7075 is used to manufacture aircraft structures and futures.

He asked for the manufacture of high-stress structural parts and high-strength and corrosion-resistant molds.

7 175

T736, a high-strength structural material of forged aircraft, has good comprehensive properties, namely, high strength, spalling corrosion resistance, stress corrosion cracking resistance, fracture toughness and fatigue strength.

7 178

Manufacturing aerospace vehicles requires parts with high compressive yield strength.

7475

Aluminum cladding and aluminum cladding plate, wing frame, longitudinal beam, etc. For the fuselage. Other parts with high strength and fracture toughness.

7A04

Aircraft skin, screws and stressed parts, such as girders, frames, ribs, landing gear, etc.
