7075 T6 Aluminum Round Bar
7075 T6 aluminum round bar is a high-performance cold-worked product made from one of the strongest aluminum alloys available.
The T6 temper denotes a two-step heat treatment process: solution heat treatment (to dissolve alloying elements into solid solution) followed by artificial aging (to precipitate strengthening phases). This results in a round bar with extraordinary tensile and yield strength—outperforming nearly all other aluminum alloys—while maintaining dimensional stability and machinability. Unlike softer aluminum grades, 7075-T6 round bars excel in structural and load-bearing roles, where they resist deformation, fatigue, and stress fractures even under extreme cyclic or static loads.
7075 T6 Aluminum Round Bar Features
Strength-to-Weight Ratio
T6-tempered 7075 delivers tensile strength (~550 MPa) comparable to low-alloy steel but at 1/3 the weight—ideal for weight-sensitive applications like aerospace and EVs.
Peak T6 Temper Performance
Maximizes strength via controlled precipitation hardening, outperforming 6061-T6 (≈310 MPa tensile) and 2024-T3 (≈470 MPa) in structural roles.
Superior Fatigue Resistance
Withstands millions of stress cycles without failure, critical for rotating parts (e.g., shafts) and cyclic-load components (e.g., suspension systems).
Precision Dimensional Control
Tight diameter and straightness tolerances (±0.02mm for small diameters) enable “near-net-shape” machining, reducing waste and production time.
Excellent Machinability
T6 temper allows efficient cutting, drilling, and threading with carbide tools, achieving fine surface finishes (Ra ≤0.8μm) for precision parts.
Temperature Resilience
Maintains 90%+ of room-temperature strength at -40°C and 80%+ at 120°C, suitable for arctic exploration gear and high-heat industrial equipment.
Our 7075-T6 aluminum round bar is manufactured with aerospace and military-grade precision, with strict control over diameter tolerances, straightness, surface finish, and grain structure.
