Anodixing Aluminium 7075 Sheet Metal Parts for Automotive Racing Components High Performance Engineering

• Lightweight: Aluminum has a density of only 2.7 g/cm³, about one-third that of steel, making it ideal for products that require weight reduction.
• Corrosion Resistance: It has excellent oxidation resistance. When exposed to air, a thin layer of aluminum oxide forms on the surface, providing protection against corrosion.
• Electrical and Thermal Conductivity: While not as conductive as copper, aluminum still offers good electrical and thermal conductivity and is preferred in many applications due to its lightweight.
• Recyclability: Aluminum is 100% recyclable and retains its properties during the recycling process, making it valuable from both an economic and environmental perspective.
• Formability: Aluminum is highly ductile and easy to process, allowing it to be stretched, extruded, and rolled into various shapes.
• Non-Magnetic: Being a non-magnetic metal, aluminum is suitable for use in devices sensitive to magnetism.

Aluminum (Al) is a lightweight, soft, and highly ductile metal that is widely used across various industries.

Sandblasting process refers to the use of high-speed sand flow impact to deal with metal surfaces, including cleaning and roughening of metal surfaces, so that the surface of aluminium and aluminium alloy parts can obtain a certain degree of cleanliness and roughness, both to improve the mechanical properties of the surface of the parts, to improve the fatigue resistance of the parts, but also increase the adhesion between the parts of the primary surface and the coating, on the durability of the coating film and the leveling of the coating, decorative and more beneficial. Found in some products, through the sandblasting process to form a kind of matte pearl silver surface effect is still very good-looking, sandblasting gives the surface of the metal material presents more subtle matte touch.

Aluminium 7075 is a high-strength alloy primarily alloyed with zinc, magnesium, and copper. It is renowned for its excellent strength-to-weight ratio, corrosion resistance, and fatigue resistance, making it a popular choice across various industries.

• High Strength: 7075 aluminium exhibits a tensile strength of up to 83,000 psi (570 MPa) and a yield strength of approximately 73,000 psi (500 MPa), making it one of the strongest aluminium alloys.
• Corrosion Resistance: While not as corrosion-resistant as some other aluminium alloys due to its copper content, 7075 can be significantly enhanced through treatments like anodizing.
• Fatigue Resistance: It excels in applications involving cyclic loading, maintaining performance and reliability over extended periods.
• Limited Ductility: With an elongation at break ranging from 5% to 11%, 7075 aluminium is not as ductile as other alloys, which can affect forming and machining processes.
• Challenging Weldability: Due to its high strength and hardness, 7075 aluminium is more prone to cracking during welding and may require alternative joining methods.

• Aerospace Industry: 7075 aluminium is extensively used for aircraft components such as wings, fuselage frames, and landing gear due to its strength-to-weight ratio and fatigue resistance.
• Defense and Military: It is used in missile components, military vehicles, and small arms like rifle receivers, where high strength and durability are crucial.
• Automotive Industry: In high-performance vehicles, 7075 aluminium is used for suspension components and chassis parts to reduce weight while maintaining strength.
• Marine Industry: For components exposed to harsh saltwater conditions, such as propeller shafts and hulls, 7075 aluminium's corrosion resistance and strength make it invaluable.
• Sports and Leisure: It is used in high-performance bicycles, rock climbing gear, and other sports equipment where lightweight and strong materials are essential.
• General Industrial Use: 7075 aluminium is also used in tooling and mold manufacturing due to its machinability and thermal properties.
