what Are the Characteristics of aluminium alloy 7075?

aluminium alloy 7075 is best known for its strength. with zinc as the primary alloying element. While not as corrosion resistant as 6061, 7075 uses zinc as its primary alloying element that allows this aluminum to compete with tensile strength of steel. It comes from the 7000 series of aluminum alloys which are known around the world for their durability and strength. While its strength is almost unmatched it is not as workable as  aluminium alloy 6061 and has a poor rating in that category. It also scores poorly in weldability and brazability.


 It has average corrosion resistance, not as great as 6061, and has fair machinability.  It has excellent mechanical properties, and exhibits good ductility, high strength, toughness and good resistance to fatigue. It is more susceptible to embrittlement than many other aluminium alloys because of microsegregation, but has significantly better corrosion resistance than the 2000 alloys. It is one of the most commonly used aluminium alloy for highly stressed structural applications, and has been extensively utilized in aircraft structural parts To further enhance its strength, it is often heat treated, which allows it to be the superior choice in applications where you need extreme strength without adding a lot of weight.

Performance advantage:
1, After the elimination of stress, processing will not deformation, warping. All super thick 7075 aluminum plate by ultrasonic detection, can ensure no blisters, impurities. 7075 aluminum plate of high thermal conductivity, can shorten the molding time, improve work efficiency.
2, 7075 aluminum plate sheet has good physical properties, processability and corrosion resistance is good, the use of age hardening can get high strength;
3, Even if the natural aging, 7xxx alloy can also achieve a very high strength, low sensitivity to crack;
4, The welding part of the heat effect, due to the heating was dissolved, so after the natural aging, the strength can be restored, so as to improve the strength of the weld seam.
