The 3000 series aluminium alloy is manganese aluminum alloy sheet whose main components are aluminium, manganese and a small amount of other alloying elements. 3000 series manganese aluminum sheet has excellent properties such as good corrosion resistance, workability and weldability. 3000 series aluminium sheet is made of manganese element as the main component. The content of manganese in 3000 series aluminum alloy sheet is between 1.0 and 1.5, it is a series with good rust resistance, it is commonly used in air conditioners, refrigerators and underneath cars in humid environments and is a more commonly used alloy than the 1000 series aluminum sheet.
The aluminium manganese alloys of the 3000 series manganese aluminum alloy sheet are widely used in construction. 3003, 3004, 3005, 3104 and 3105 are widely used because the content of manganese in the aluminium manganese alloys sheet is stable around their saturation point. The aluminium alloys of the 3000 series aluminium sheet have a suitable elongation, good corrosion resistance and good processing properties. The common grades of 3000 series aluminium alloys are:
3003 aluminium alloy sheet: has excellent corrosion resistance, machinability and weldability, commonly used in the manufacture of chemical containers, roofing panels, decorative materials, cable casings, food processing and storage equipment, etc.
3004 aluminium alloy sheet: with good corrosion resistance and machinability, commonly used in the manufacture of beverage cans, cosmetic packaging, automotive parts, construction materials, etc.
3105 aluminium alloy sheet: with good corrosion resistance and machinability, commonly used in the manufacture of roofing panels, pipes, cable casings, construction materials, automotive parts, etc.
