The values below are typical room-temperature properties for 6061 and are representative of extruded, drawn, or rolled product. Exact numbers vary with section size and product form; final inspection is reported on the MTC.

템퍼 선택 가이드

• O / T4: for fabricated assemblies that are formed or welded before final use.
• T6: maximum strength for structural frameworks.
• T651: stress-relieved for improved stability in precision assemblies.

주요 특징

무게 대비 강도 비율

The hollow section gives high stiffness per unit weight, ideal for transport and handling structures.

용접성

6061 tubes weld readily, supporting on-site fabrication of frames and supports.

내식성

Good general resistance; anodizing or coating extends service life outdoors.

• Structural frameworks and machine supports
• Jigs, fixtures, and racking
• Architectural railings and trim
• Recreational and consumer goods

가공 및 표면 마감 참고 사항

• 절단: supplied cut-to-length with deburred ends.
• 용접: TIG/MIG with 4043 or 5356 filler; avoid contamination at the joint.
• Finishing: anodizing, powder coating, or polishing available.

품질 문서 및 검사

• 제강 시험 증명서(MTC): every shipment includes an MTC reporting chemical analysis and mechanical results against the ordered specification.
• Inspection: dimensional checks, visual surface inspection, and mechanical sampling are carried out before dispatch.
• Standards: material can be supplied to ASTM, EN, GB/T, or JIS requirements on request.
• Third-party testing: SGS or other nominated laboratory reports can be arranged when required by the project.
