6061 aluminum plate

6061 aluminum plate

6061 aluminum plate is a corrosion-resistant building material used in shipbuilding. The main alloying elements are magnesium and silicon. It has medium strength, good corrosion resistance, weldability, and good oxidation effect. It is widely used in various industrial structural parts that require certain strength and high antimicrobial corrosion resistance.
6061 aluminum plate has excellent processing performance, good corrosion resistance, high toughness, no deformation after processing, easy color film, and excellent oxidation effect.Its main alloying elements are magnesium and silicon, with small amounts of copper and chromium added to optimize performance. This unique alloy formulation endows 6061 aluminum plate with moderate strength, good corrosion resistance, weldability, and excellent processing properties. Whether in the transportation sector (automobile bodies, ship structures), machinery manufacturing, mold making, or the 3C industry, 6061 standard aluminum plate can meet the demands of various complex environments thanks to its superior performance.

Common tempers for 6061 aluminum plate

Common tempers for 6061 aluminum plate include O, T4, T6, and T651. The T651 temper alloy is formed by stretching and stress relief on the T6 temper, making it more suitable for processing and forming.
O refers to the annealed state, suitable for products that have undergone full annealing to obtain the minimum strength.
T4 is solution heat treatment followed by natural aging, suitable for products that have undergone solution heat treatment without further cold working and then naturally aged.
T6 is solution heat treatment followed by artificial aging, suitable for products that have undergone solution heat treatment without further cold working and then artificially aged.
T651 is pre-stretched based on T6, resulting in lower internal stress and making it suitable for machining large parts.

6061-T6 aluminum plate is a commonly used state. T6 represents the heat treatment state of the aluminum plate, determining its mechanical properties. 6061 medium-thick plates in this state undergo quenching, plate slicing, stretching, aging treatment, sawing, polishing, packaging, and solution heat treatment. After this process, no cold working is required, and straightening can be performed without affecting mechanical properties.

Application of 6061 aluminum plate

Various industrial structural parts that require certain strength, weldability and high corrosion resistance, such as manufacturing trucks, buildings, ships, trams, furniture, mechanical parts, precision machining, and industrial materials are widely used.

Precision Machinery's High Material Requirements

In precision machinery manufacturing, the requirements for materials are extremely high. First, the material must possess high strength and good rigidity to ensure the stability and precision of the machinery. Second, the material must have good machinability, facilitating cutting, drilling, and other machining operations. Furthermore, the material's corrosion resistance is also crucial, ensuring that the machinery is not easily corroded during use, thereby extending its service life.
