6061 square bar is an extruded profile with a square cross-section, commonly supplied in the T6 temper for maximum strength and dimensional stability. Its balance of machinability and corrosion resistance makes it a go-to section for both structural and precision-engineering work.
Square bars are supplied with side dimensions from 8 mm to 300 mm and lengths of 1000 – 6000 mm. T6511 is the standard extruded-and-stress-relieved temper for bars.
| 形式 | 脾气 | Side (mm) | 长度(毫米) |
|---|---|---|---|
| Square bar | T6, T651, T6511 | 8 – 300 | 1000 – 6000 |
| 要素 | 内容 (%) |
|---|---|
| 硅 (Si) | 0.40 – 0.80 |
| 铁(Fe) | 0.70(最大值) |
| 铜 (Cu) | 0.15 – 0.40 |
| 锰 (Mn) | 0.15 最大值 |
| 镁(Mg) | 0.80 – 1.20 |
| 铬 (Cr) | 0.04 – 0.35 |
| 锌 (Zn) | 最大 0.25 |
| 钛 (Ti) | 0.15 最大值 |
| 其他(每项) | 0.05 最大值 |
| 其他(共计) | 0.15 最大值 |
| 铝 (Al) | 剩余 |
以下数值为 6061 的典型室温性能,代表挤压、拉拔或轧制产品。具体数值因截面尺寸和产品形态而异;最终检验结果以质保书 (MTC) 形式报告。.
| 脾气 | 拉伸强度(兆帕) | 屈服强度(兆帕) | 伸长率 (%) | 布氏硬度 (HB) |
|---|---|---|---|---|
| O | 124 | 55 | 25 | 30 |
| T4 | 241 | 145 | 22 | 65 |
| T6 | 310 | 276 | 12 | 95 |
| T651 | 310 | 276 | 12 | 95 |
6061 machines cleanly in T6, making it efficient for screw-machine products, fittings, and repeating components.
The square geometry provides predictable load paths for frameworks, jigs, and supports.
Good in most atmospheric environments; anodizing adds a durable, decorative surface.
每批货物均附带质保书 (MTC),报告根据订购规范进行的化学成分分析和力学性能结果。.
发货前进行尺寸检查、外观表面检查和力学性能取样。.
T6 and T6511 are the most common for structural and machined bars; T6511 adds stress relief for better stability after cutting.
Yes. 6061 anodizes well and is frequently specified for architectural and decorative sections.
It welds well with standard aluminum processes; design for some strength loss in the heat-affected zone.
