Aluminum sheet factory - HC Aluminium supply aluminum sheet product with different alloy from 1000 series to 8000 series. Due to the different alloy compositions, the strength of aluminum sheet can be reduced from 7000 series, 2000 series, 4000 series, 6000 series, 5000 series, 3000 series and 1000 series according to the coding sequence. 1000 series pure aluminum sheet is softer and less strong, while 2000 series and 70000 series heat-treated aluminum alloys are stronger. The corrosion resistance of the alloy aluminum sheet will directly affect the service life of the alloy aluminum sheet, especially for products that work under extreme conditions of high corrosion, more attention should be paid to the corrosion resistance of the alloy aluminum sheet. The corrosion resistance of the alloy aluminum sheet includes chemical corrosion, crystal resistance. inter-corrosion and other properties. Generally speaking, 1000 series pure aluminum sheet has good corrosion resistance, 5000 series mainly performs well, followed by 3000 series and 6000 series, 2000 series and 7000 series are weak.
As an professional and reliable aluminum sheet factory in China, HC Aluminum have strict quality requirements of aluminum sheet product:
1. The surface of the aluminum sheet should be cleaned, and cracks and oxidized debris are not allowed.
2. The surface of the aluminum sheet is allowed to have defects such as indentation, scratches, roll indentation, etc., but its depth cannot exceed the allowed negative error of the aluminum sheet, and the minimum thickness is ensured.
3. If there is a protective film on the surface of the aluminum sheet, the protective film must not have defective parts and air bubbles.
4. The surface of the aluminium sheet promises to repair the defects within the range of thickness difference.
5. Other requirements: There are demanders and suppliers to formulate their own.
From the point of view of aluminum sheet factory alloy series, the formability of the 1000 series is good, the 3000 series and the 5000 series are good, the 2000 series and the 6000 series are average, and the 7000 series basically cannot be formed and processed. The state has a greater impact on the formability of aluminum alloy sheets. The quenched state (O state) has good formability, and the higher the strength, the worse the formability.
