Aluminum is a versatile material known for its lightweight properties, corrosion resistance, and strength. Among the various aluminum alloys available, the 7000 series aluminum stands out for its exceptional strength and toughness. In this comprehensive guide, we will delve into the characteristics, applications, and properties of 7000 aluminum.
What Is 7000 Series Aluminum
The 7000 Series Aluminum comprises a group of aluminum alloys known for their high strength properties. These alloys are characterized by having zinc as the primary alloying element. They are recognized for their exceptional strength capabilities, making them one of the strongest series of aluminum alloys available. Additionally, alloys within the 7000 Series exhibit excellent fatigue properties, but in the T6 condition, their fracture toughness may be comparatively lower than some other aluminum alloys. While spot welding is a feasible method for joining these alloys, fusion welding is generally not recommended. To address corrosion concerns, it is advisable to apply protective measures such as anodization, priming, painting, or the use of a chemical film.
7000 Series Aluminum Properties
The 7000 Series Aluminum possesses a wide spectrum of mechanical properties. Its tensile strength at yield spans from 69.0 to 730 MPa, indicating a significant range of strength capabilities. The shear modulus falls between 25.0 and 27.6 GPa, showcasing the material’s resistance to shear stresses. Shear strength varies from 50.0 to 400 MPa, underlining its ability to withstand shear forces. Additionally, the modulus of elasticity ranges from 67.0 to 73.0 GPa, reflecting the material’s elasticity and ability to return to its original shape when subjected to external forces. These diverse properties make the 7000 Series Aluminum a versatile choice for applications requiring a combination of strength, resilience, and durability.
7000 Series Aluminum Grade
The 7000 Aluminum comprises several significant grades, including 7010, 7050, 7068, 7075, and 7175. Each grade offers distinct properties tailored to specific requirements. For example, 7010 is known for its high strength and toughness, while 7050 excels in corrosion resistance and strength. 7068 is an advanced alloy prized for its exceptional mechanical properties. 7075, a prominent grade in the series, is celebrated for its remarkable strength-to-weight ratio. Finally, 7175 strikes a balance between strength, toughness, and corrosion resistance. These grades collectively demonstrate the diverse capabilities and versatility of the 7000 Aluminum in various industrial contexts.
