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.

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.
Linsy is a Shenzhen-based aluminum supplier with more than 20 years of experience. Our quality system is certified to ISO 9001, ISO 14001, and ISO 45001. Every order ships with a mill test certificate (MTC). SGS third-party test reports are available on request. Typical custom lead time is 10–60 days depending on temper, size, and quantity.

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.
Every order ships with an MTC, and SGS third-party test reports are available on request.
Custom aluminum orders typically ship in 10–60 days depending on alloy, temper, size, and quantity. Stock or standard sizes may be faster — ask our team.
Yes. Every order includes an MTC. SGS third-party test reports are available on request.
Yes. We provide CNC machining, laser cutting, welding, anodizing, polishing, and powder coating so parts can be delivered closer to finished form.
Send your alloy, temper, dimensions, quantity, and required standard. Our team will confirm availability, lead time, and pricing.
