When speak of 2024 aluminum vs 7075, we all know that 2024 and 7075 aluminum alloys belong to the “hardliners” in the aluminum family – high-strength hard aluminum, which can be used in the manufacture of aircraft. 2024 aluminum alloy and 7075 aluminum alloy are relatively hard materials in aluminum alloys, and 2024 aluminum alloy is harder. 7075 aluminum alloy is mainly used for aviation materials and some industrial materials with high hardness requirements.

2024 aluminum vs 7075

Now let’s see the difference of 2024 aluminum vs 7075:

7000 series aluminum alloy: 7000 series aluminum alloy means 7075 aluminum alloy mainly contains zinc. It also belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy, a heat-treatable alloy, and a super-hard aluminum alloy with good wear resistance. It also has good weldability, but poor corrosion resistance.

2000 series aluminum alloy: 2000 series aluminum alloy represents 2024 aluminum, 2A16 (LY16), 2A02 (LY6). The 2000 series aluminum plate is characterized by high hardness, among which the copper element content is the highest, about 3-5%. 2000 series aluminum rods belong to aviation aluminum materials, which are not often used in conventional industries.


When applied to aircraft industry, 2024 aluminum vs 7075 also show difference. Metals that can be used to make aviation equipment must have high mechanical strength. The tensile strength of 2024 aluminum alloy is σb (MPa) ≥390, the yield strength σ0.2 (MPa) ≥245, the Brinell hardness is 120-130HB, which is 4-10 times that of pure aluminum, and can be used as aircraft structural parts, automobiles Wheels, rivets, etc. The tensile strength of 7075-T651 is 524Mpa, the 0.2% yield strength is 455Mpa, the Brinell hardness is 150HB, and the mechanical strength is higher than that of 2024, which is comparable to the strength of low-carbon steel. It is used in aerospace industry, mold processing, etc.
