7020 (AlZn4.5Mg1) aluminum alloy rods is a 7000-series aluminum alloy: the main alloying addition is zinc and it is formulated for primary forming into wrought products. 7020 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-7020. H17 is the British Standard (BS) designation. A97020 is the UNS number. Additionally, the EN chemical designation is AlZn4,5Mg1. And the AFNOR (French) designation is A-Z5G.
7020 (AlZn4.5Mg1) aluminum alloy rods
The main characteristic is hardness.7020 (AlZn4.5Mg1) aluminum alloy rods is a high hardness, high strength aluminum alloy, often used in the manufacture of aircraft structures.It requires high strength, strong corrosion resistance of high stress structural parts, mold manufacturing.
7020 (AlZn4.5Mg1) aluminum alloy rods is used for parts with the same static strength and requiring high resistance to stresscorrosion cracking, such as aircraft and missile parts-landing gear hydraulic cylinders and extrusions. The fatigue performance of theparts is roughly equal to that of 7075-T6 alloy, while the toughness is slightly higher.
