Key Features of 7068 aluminum bar
Superior Strength: 7068 aluminum offers extremely high strength, with yield strength up to about 700 MPa, significantly higher than 7075.
Corrosion Resistance: It provides excellent corrosion resistance, making it suitable for outdoor and marine environments.
Machinability: It is easy to machine, weld, and form, making it ideal for complex component fabrication.
Anodising: It responds well to anodizing, producing a more wear-resistant surface under hard anodizing.
Application of 7068 T6 T6511 T76511 Aluminum Round Bar
The 7068 aluminum alloy is widely used in applications requiring lightweight, high-strength materials that also offer good corrosion resistance. Some common sectors and uses include:
Defense and Military:
Aircraft and Aerospace: Ideal for aircraft structural components, particularly those where high strength is needed, such as aircraft fuselage or wing structures.
Armor: 7068 is used for lightweight armor plates that need to be stronger and lighter than traditional steel armor.
Automotive:
For applications in the automotive industry where weight reduction and high strength are needed, such as in high-performance vehicle components, chassis, or brake systems.
Sports and Recreation:
Used in high-end bicycles, sporting goods (e.g., golf clubs, bike frames), and motorcycle parts that require both high strength and reduced weight.
Industrial Equipment:
7068 is specified for critical industrial equipment where strength and weight are important, such as crane components, robotic arms, or machine tool components.
Marine:
Used in the marine industry for high-stress parts like hull frames, propeller shafts, and structural components exposed to saltwater environments.
Aerospace:
7068 is gaining traction in aerospace applications where the need for lightweight yet strong materials is critical for achieving fuel efficiency and performance.
