There are many grades of aluminum alloy materials. Different grades of materials have different elements and contents. Different element contents determine different physical and mechanical properties, which in turn determines that different grades of materials are suitable for different fields and products. Then Xiaobian today In exchange with you, the differences and application fields of the two most commonly used aluminum plates 5083 and 6061.
5083 aluminum plate is the representative product of the 5 series, most of the state is H321, H116, usually used in the shipbuilding industry, 6061 aluminum plate is the representative product of the 6 series, the state is generally 6061-T6 aluminum plate, 6061-T651, 6061-T652 aluminum plate, T6 is After the solution heat treatment (quenching), artificial aging is performed to improve the strength and hardness of the aluminum plate. So what are the specific differences between 5083 aluminum plate and 6061 aluminum plate?
5083 aluminum plate is AL-Mg series rust-proof aluminum alloy, which is characterized by excellent welding performance and good corrosion resistance.
1.Weldability: The welding performance of 5083 alloy is good-one can use various welding methods to weld, and the strength of the weld can be equal to the basic strength of the annealed state. At the same time, it has good extensibility, cold formability, and reliable corrosion resistance. As the temperature decreases, the tensile strength, yield strength, and elongation of the base metal and welded joints increase, and the low temperature toughness is very good.
2.Corrosion resistance: The 5083 alloy has good corrosion resistance in various states, and has good corrosion resistance to the atmosphere, fresh water, sea water, alcohol, gasoline and diesel, organic acids, concentrated nitric acid, and various foods. However, 5083 alloy is prone to stress corrosion cracking. To avoid stress corrosion cracking, the working temperature of 5083 alloy is preferably not more than 65 degrees.
Based on the above two significant features of 5083, the application fields of 5083 include: low temperature applications: storage and transportation of petroleum and industrial gases. High-speed trains, subways, pressure vessels, hulls or the outer layers of buildings, such as speedboats, naval and construction ships, road transport: commercial vehicles and trailers. Common engineering applications: mechanical parts, fixtures, tooling fixtures, platforms; base plates and general tools.
The main alloying elements in 6061 aluminum plate are Mg and Si, which have medium strength, good corrosion resistance, weldability, and good oxidation effect. Alcoa 6061-T651 has excellent characteristics such as excellent processability, good corrosion resistance, high toughness, no deformation after machining, easy coating film, and excellent oxidation effect.
Its application fields are relatively wide: suitable for aerospace, military products, tooling fixtures, blow molds, thermoforming molds, automotive molds, electronic product machining and precision equipment machining.
The comparison between 5083 and 6061 is relatively obvious:
1.Material of 1.6061 alloy after heat treatment (T6) to reach medium strength, its strength is higher than 5083;
2.The material of aluminum plate 6061-T651 is easier to process than 5 series alloys such as 5083. Shows better machining performance when machining with single-point or multi-axis diamond tools;
3.6061 alloy has excellent surface treatment and anodic oxidation characteristics, and reflects the hard oxidation effect slightly better than 5083 and other 5 series materials;
4.6061 also has a certain degree of corrosion resistance, and will not decrease in the case of exposure to air, but it is not as strong as 5083;
