In terms of mechanical properties, the tensile strength of 3003H24 aluminum sheet is 145-195Rm/MPa, while the tensile strength of 5052H24 aluminum sheet is as high as 230-280Rm/MPa, which is much higher than 3003H24 aluminum sheet; the extension strength of 3003H24 aluminum sheet is 115Rm/MPa, while 5052H24 aluminum sheet The elongation strength of the aluminum plate is 150Rm/MPa. Therefore, the performance of 5052 aluminum plate is significantly better than that of 3003 aluminum plate.
From the chemical composition, 3003 aluminum plate is an aluminum-manganese alloy, and the main alloying element is manganese. 5052 aluminum plate is an aluminum-magnesium alloy, and the main alloying element is magnesium. The aluminum content of 3003 aluminum plate is slightly higher than that of 5052 aluminum plate, but the magnesium element of 5052 has more strength and toughness.
In terms of common specifications, 3003 aluminum plates are mainly thin plates, and there are not many applications for thick plates; and 5052 aluminum plates are widely used in addition to thin plates.
From the scope of application, 3003 aluminum plate is mainly used in humid environments, such as product packaging, refrigerators, air conditioners, cold storage, ventilation ducts, and so on. The 5052 aluminum plate is often used in electrical enclosures, transportation vehicles, pressure vessels, etc., and is a common material for manufacturing automobile, aircraft fuel tanks, and fuel pipes.
