7075 (DIN 3.4365, EN AW-7075, UNS A97075) is a zinc-magnesium-copper aluminium alloy - the highest-strength commercially available wrought aluminium alloy. In the T6 (peak aged) condition, 7075 achieves a minimum tensile strength of 503 MPa with a density of only 2.81 g/cm3, giving it a specific strength (strength-to-weight ratio) that significantly exceeds medium carbon steel and approaches some low-alloy steels. The alloy's strength comes from its high zinc (5.1-6.1%), magnesium (2.1-2.9%), and copper (1.2-2.0%) additions, which form coherent MgZn2 (eta phase) precipitates during artificial ageing that create very fine-scale precipitation hardening. 7075 in T6 and T651 conditions is the industry standard for aircraft structural components, high-performance mould tooling for plastic injection moulding, and precision engineering applications where minimum weight at maximum strength is the design objective. The T651 designation confirms controlled stretching after quenching to relieve residual stress - always specify T651 for plate and thick bar where dimensional stability during heavy machining is required.
Nifty Alloys supplies 7075-T6 / 3.4365 aluminium from stock in Dubai, UAE, in round bar, flat bar, plate/sheet, square bar, and hollow bar. T651 stress-relieved plate and bar are available for mould tooling and aerospace structural applications requiring maximum dimensional stability. All material is supplied with EN 10204 3.1 Mill Test Certificates as standard, confirming chemical composition, mechanical properties, and temper designation. AMS 4122 (bar/rod) and AMS 4045 (plate) aerospace-certified material is available from our qualified mill sources - specify at enquiry stage. We deliver across the UAE within 24-48 hours and export to Saudi Arabia, Kuwait, Qatar, Oman, and Bahrain. Contact our team for same-day quotation.
