6061 aluminum square tube is a heat-treatable extruded section that delivers a high strength-to-weight ratio with good weldability and corrosion resistance. It is well suited to load-bearing frameworks, machine supports, and architectural railings.
可选格式: square tube / rectangular tube
常见脾气: O / T4 / T6 / T651
处理支持: cut-to-length / CNC / welding prep / anodizing
质量文件: 每笔订单均附有MTC报告
6061 square tube is an extruded hollow section that combines rigidity with light weight. Supplied mainly in T6, it offers the stiffness needed for frameworks, jigs, and racking while remaining easy to cut, weld, and finish.
Square tubes are supplied with outer side dimensions from 10 mm to 300 mm, wall thicknesses of 1 – 20 mm, and lengths of 1000 – 6000 mm.

| 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 |

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 |
The hollow section gives high stiffness per unit weight, ideal for transport and handling structures.
6061 tubes weld readily, supporting on-site fabrication of frames and supports.
Good general resistance; anodizing or coating extends service life outdoors.
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。.
Typical stock covers 1 – 20 mm wall across side dimensions from 10 mm to 300 mm; other sizes can be quoted.
In T6 it provides good load capacity at low weight and is widely used for frameworks, guards, and supports.
Yes. Proper surface preparation gives a durable coated finish for indoor and outdoor use.
