What Are Uses of 5052 Aluminum Circle Blanks
5052 aluminum circle belongs to Al-Mg alloys, and its main alloying element is magnesium, with a content between 2.2 and 2.8%. In addition, it also contains a small amount of silicon, copper, zinc, manganese, chromium, iron and other elements. The elements cooperate with each other to give 5052 aluminum discs excellent performance.
Mechanical properties
Moderate strength: With medium strength, its tensile strength is between 173 - 244MPa, and the conditional yield strength is ≥70MPa. This strength level enables it to maintain structural stability under certain loads and is suitable for a variety of application scenarios.
Good plasticity: The plasticity of 5052 aluminum discs is high, especially in the annealed (O) state, with good cold stamping performance, and can easily perform various forming processes to meet the manufacturing needs of complex-shaped products. During semi-cold hardening, the plasticity is still good, while the plasticity decreases during cold hardening.
High fatigue strength: The alloy has high fatigue strength and can maintain the performance of the material for a long time under repeated loading and unloading. It is not easy to suffer from fatigue fracture, which is crucial for some parts that need to withstand cyclic stress.
Physical properties
Low density: The density of 5052 aluminum disc is about 2.72g/cm³, which is relatively light. This feature makes it have significant advantages in some industries with strict weight requirements, such as aerospace, transportation, etc., which can not only reduce the overall weight but also reduce energy consumption.
Good thermal conductivity: It has good thermal conductivity, can quickly transfer heat and dissipate heat evenly. This makes 5052 aluminum discs perform well in applications that require efficient heat dissipation, such as heat sinks for electronic equipment.
Chemical properties
Excellent corrosion resistance: 5052 aluminum circle discs have excellent corrosion resistance, especially in marine and industrial environments. This is due to the role of magnesium in its alloy composition and a dense oxide film naturally formed on the surface, which can effectively prevent the erosion of external corrosive media and extend the service life of the product. Due to its relatively low magnesium content, compared with other aluminum alloys with a magnesium content greater than 3.5%, this aluminum disc is not prone to stress corrosion cracking (SCC), which further improves its reliability in complex environments.
Good weldability: 5052 aluminum discs have excellent welding performance, and gas welding, arc welding, resistance welding, spot welding, seam welding and other welding methods can achieve good results. Although there is a certain tendency of crystallization cracks during argon arc welding, by selecting appropriate welding processes and solders, such as using 5A03 alloy as solder, the air tightness of the weld can be effectively improved, and the crack tendency can be eliminated to ensure welding quality.
Applications
Shipbuilding: In shipbuilding, 5052 aluminum circle blanks are often used to manufacture various hatch covers, such as oil-tight hatch covers. Its excellent corrosion resistance can effectively resist the erosion of seawater, ensure the sealing and structural strength of the hatch covers, and prevent seawater and rainwater from invading the cargo hold. For the oil-tight hatch covers of yachts, 5052 - H32 aluminum discs are an ideal material choice, with a common size of 2.0 * 600mm. In addition, 5052 aluminum discs can also be used for some decorative parts of ships, and its good polishing effect and surface quality can enhance the overall beauty of the ship.
Kitchenware manufacturing: In the kitchenware industry, 5052 aluminum discs are widely used in the manufacture of non-stick pans, pressure cookers, baking trays and other products. Its good processing performance enables kitchenware to have various exquisite appearances and practical structures; moderate strength can ensure the durability of kitchenware in daily use; and excellent corrosion resistance ensures that kitchenware will not rust or corrode when in contact with food and various cooking media, ensuring food safety.
Road sign production: 5052 aluminum discs have good reflectivity and surface quality, making them suitable for making road signboards. They can clearly reflect light under different light conditions, improve the visibility of signboards, and provide protection for traffic safety. At the same time, their corrosion resistance can ensure that the signboards can be used for a long time in outdoor environments without fading or damage.
