7075 T651 Cold Finished Aluminum Round Bar
GNEE 7075-T651 aluminum round bar is a high-strength aluminum product widely recognized for its exceptional strength-to-weight ratio, making it a preferred material for aerospace and high-performance applications. This alloy is primarily zinc-based, with controlled additions of magnesium, copper, and chromium, which contribute to its outstanding mechanical performance.
The combination of remarkable strength and good corrosion resistance allows 7075 aluminum to be used in the production of lightweight yet durable components. As a result, it is commonly applied in aircraft structures, automotive components, and sporting equipment.
GNEE supplies 7075 aluminum round bars, one of the strongest commercially available aluminum alloys, offering strength levels comparable to many steels. This alloy demonstrates good fatigue resistance and average machinability, although its corrosion resistance is lower than that of many other aluminum alloys. While 7075 aluminum can be formed using conventional methods, it requires greater precision and care during processing. It is typically selected for demanding applications where lower-cost alloys do not meet performance requirements, such as aircraft structural components.
7075 Aluminum Round Bar is one of the strongest aluminum alloys, with a great strength-to-weight ratio and consistent performance under high-stress circumstances. It is frequently compared to 2024, but is preferred when maximal strength is desired.
This aluminum-zinc alloy (with 1-8% zinc and lower quantities of magnesium, copper, and chromium) is precipitation-hardened to obtain extremely high mechanical strength while preserving good toughness and fatigue resistance.
