3000 series aluminum coil is an Al+Mn (1.0-1.5) alloy, which has good rust and corrosion resistance characteristics. The main alloys are 3003 3A21. Because of its good rust resistance, it will be widely used in some household appliances in humid environments, such as air conditioners, refrigerators, car bottoms, etc., and can be used for a long time. The price of 3 series aluminum coil is higher than that of 1000 series, and it is widely used in industrial and domestic scenarios.
3 series 3003 aluminum coils are often used for processing parts that require good formability, high corrosion resistance and good weldability. They have higher strength requirements than 1 series and are more widely used. Such as kitchenware, food and chemical products processing and storage devices, tanks and tanks for transporting liquid products, various pressure vessels and pipes processed with thin plates.
3 series 3004 aluminum coil has a higher strength than 3003, and is commonly used in all-aluminum pop-top can bodies, chemical product production and storage devices, sheet metal processing parts, construction processing parts, construction tools, and various lighting components.
3 series 3105 aluminum is the highest strength among these types, and is mostly used in construction, such as room partitions, baffles, movable house panels, gutters and downspouts, sheet metal forming parts, bottle caps, bottle stoppers, etc.
