Aluminum Rod 7075 6061 T6 Aluminum Solid Bar 8mm 18mm Hard Aluminum Hexagon Bar

Aluminum Hexagonal Bar

Manufactured from premium 6061-T6, 6063-T5, and 6082-T6 aerospace-grade aluminum alloys via single-step hot extrusion process, ensuring across-flat dimensional tolerance within ±0.10 mm, across-corner tolerance ≤0.15 mm, and straightness ≤0.3 mm/m. On-line quenching combined with staged artificial aging heat treatment is applied to achieve refined and uniform grain structure, resulting in consistent hardness ≥HB90, tensile strength ≥310 MPa, yield strength ≥270 MPa, and elongation ≥10%, with batch-to-batch mechanical property variation below 5%. Full traceability is guaranteed through 100% per-bar dimensional inspection and complete batch testing of mechanical and chemical properties. Equipment includes German SPECTRO direct-reading spectrometer, Mitutoyo surface roughness tester, Tesa height gauges, and HEXAGON CMM. Third-party test reports (SGS/BV) available upon request. Surface finish options include bright oxidation, natural oxidation, or chrome-free chemical polishing, achieving Ra ≤0.8 μm, free of extrusion marks, scratches, cracks, or inclusions. Standard length up to 6000 mm, maximum across-flat size 150 mm. Custom dimensions within ±0.5 mm tolerance and non-standard alloys accepted. Minimum order quantity: 5 tons, typical lead time 10–15 days. We have maintained 100% batch acceptance rate for eight consecutive years while supplying high-precision machinery manufacturers, automation system integrators, and defense contractors requiring long-term lot consistency and full material certification.
