7068 aluminum is an ultra-high-strength 7xxx series alloy, often cited as the strongest commercial aluminum alloy with tensile strength around 700 MPa — comparable to some soft steels. It was originally developed as a higher-strength successor to 7075 for ordnance and defense, and now serves aerospace, automotive, medical, and sporting-goods applications where strength-to-weight is critical. Linsy supplies 7068 in plate, tube, bar, and wire with mill test certificates on every order.
可选格式： plate, tube, bar / rod, wire
常见脾气： T651, T6511
处理支持： CNC 加工、激光切割、TIG/MIG 焊接、阳极氧化、抛光、粉末喷涂
质量文件： 每笔订单均附有MTC报告

7068 aluminum (EN AW-7068, AlZn8MgCu) is supplied to common wrought-alloy specifications. Typical standards by form: ASTM B209 (sheet and plate), ASTM B221 (extruded tube, bar, and profiles), ASTM B211 (bar and rod), ASTM B247 (forging stock), and ASTM B313 (welded tube). Always confirm the exact specification and temper with our team for your order.

Values are typical for the T651 condition (~700 MPa ultimate). Confirm exact figures with the mill certificate; verify the Mn limit (AA 7068 may allow up to 0.30 max).
Ultimate tensile around 700 MPa, near some steels.
Top choice where mass must be minimized.
Better than 7075 in many service environments.
Supplied as machined or formed parts.
Linsy machines and laser-cuts 7068 and applies anodizing or painting for corrosion protection. Welding is not recommended.

Around 700 MPa ultimate tensile in T651 — the strongest of the common aluminum alloys, comparable to some soft steels.
It is stronger, with similar corrosion behavior, but less widely stocked. Choose 7068 when you need maximum strength.
No, it is a machined-part alloy.
每笔订单均附带 MTC，可根据要求提供 SGS 第三方测试报告。.
