7075 aluminum7075 is an aluminum alloy, with zinc as the alloying element. It is strong, with good fatigue strength and average machinability, but is not weldable and has less resistance to corrosion than many other alloys. It is commonly produced in several heat temper grades, 7075-O, 7075-T6, 7075-T651. Additional recommended knowledge
Basic propertiesAs with all aluminum alloys, 7075 has a specific gravity of 2.73 (0.098 lb/cubic inch). Mechanical propertiesThe mechanical properties of 7075 depend greatly on the temper of the material. [1] 7075-0Un-heat-treated 7075 (7075-0 temper) has maximum tensile strength no more than 40,000 psi (276 MPa), and maximum yield strength no more than 21,000 psi (145 MPa). The material has elongation (stretch before ultimate failure) of 9-10%. 7075-T67075 tech sheet T6 temper 7075 has an ultimate tensile strength of 74,000 - 78,000 psi (538 - 510 MPa) and yield strength of at least 63,000 - 69,000 psi (434-476 MPa). It has elongation of 5-8%. 7075-T651T651 temper 7075 has an ultimate tensile strength of at least 67,000 - 78,000 psi (462 - 538 MPa) and yield strength of 54,000 - 67,000 psi (372-462 MPa). It has elongation of 3-9%. Uses7075 is widely used for construction of aircraft structures, such as wings and fuselages. [2] Its strength and light weight are also desirable in other fields. Rock climbing equipment and bicycle components are commonly made from 7075 aluminum alloy. The bicycle industry is also using 7005 and 6061 aluminum alloys. See alsoAluminium 6351 References |
