Good corrosion resistance: it can maintain stable performance in various harsh environments, such as humidity, acid and alkali, prolong service life and ensure the reliability and safety of new energy equipment.

Excellent machinability: easy to punch, stretch and bend, which can meet the manufacturing requirements of parts with different shapes and sizes, improve production efficiency and reduce production costs.

Recyclable: Aluminum alloy has good recyclability and high recycling value, which conforms to the concept of environmental protection and sustainable development and reduces resource waste.

Good thermal and electrical conductivity: some aluminum plates have good thermal and electrical conductivity, such as 1060 aluminum plate, which is suitable for parts that need heat dissipation or electrical conductivity, such as automobile radiator and battery soft connection.

manufacturing process

Melting: Put high-purity aluminum ingots and alloying elements such as magnesium, silicon, copper, manganese, etc. into a melting furnace for heating and melting, and remove impurities and gases through stirring, refining and other processes to obtain aluminum alloy melt with uniform composition and high purity.

Casting: the molten aluminum alloy is poured into a pre-designed mold and solidified under natural cooling or forced cooling conditions to obtain an aluminum alloy ingot. Common casting methods include gravity casting, pressure casting and centrifugal casting.

Hot rolling: After the ingot is heated to a certain temperature, it is rolled on a hot rolling mill for many times to gradually reduce its thickness, improve the microstructure and properties of aluminum plate, and improve its strength and toughness.

Cold rolling: further rolling the hot rolled aluminum plate at room temperature can obtain higher dimensional accuracy and surface quality, and further improve the strength of aluminum plate.

Surface treatment: In order to improve the corrosion resistance, wear resistance and decorative properties of aluminum plate, anodizing, electrophoretic coating, powder spraying and other surface treatment processes are often used to form a protective film or coating on the surface of aluminum plate.
