3004 aluminium alloy is an alloy in the wrought aluminium-manganese family (3000 or 3xxx series). It is similar to the 3003 मिश्र धातु, लगभग के जोड़ को छोड़कर 1% मैग्नीशियम. It can be cold worked (but not, unlike some other types of aluminium alloys, गर्मी से इलाज) to produce tempers with a higher strength but a lower ductility. Like most other aluminium-manganese alloys, 3003 is a general-purpose alloy with moderate strength, अच्छी व्यावहारिकता, and good corrosion resistance. It is commonly rolled and extruded, but typically not forged. एक गढ़ा मिश्र धातु के रूप में, it is not used in casting.
3003 एल्यूमीनियम शीट एक बहुत ही लागत प्रभावी ग्रेड है, as it combines substantial strength and corrosion resistance, with an attractive finish. It is used for stamped and formed parts and can be finished with mechanical and organic finishes.
NS 5052 aluminum alloy is used to make beverage closure without internal pressure. The raw material is 5052 H19 aluminum sheet, the material is first oxidized to improve the coating adhesion and corrosion resistance. After the two sides are painted, the can lid is formed. इसलिए 5052 aluminum is another material for processing closures. 5052 aluminum sheet has good oxidation coloring effect, excellent metal texture and hardness, wear resistance and corrosion resistance, long service life, and is widely used in high-end mobile phone casings, high-end air-conditioning casings and other fields with high requirements for oxidation and metal texture.
