Product Capacities of Alloy 7068

Typical Uses

7068 aluminum alloy, initially developed for its high strength in military ordnance, boasts the title of strongest commercially available aluminum. This translates to applications requiring exceptional strength-to-weight ratios, like connecting rods, high-performance suspension components, and demanding aerospace parts. Additionally, its good corrosion resistance and machinability make it valuable for applications like medical prosthetics and high-end sporting goods.

FAQs

What is the Difference Between 7068 and 7075 Aluminum?

7068 aluminum is known for its high tensile strength and great performance under stress, making it one of the strongest aluminum alloys available. 7075 aluminum is also very strong, but it balances machinability with durability better. Both alloys are corrosion-resistant and used for high-performance applications. But, 7068 is usually chosen when maximum strength is essential.
