3004 aluminium alloy is an alloy in the wrought aluminium-manganese family (3000 or 3xxx series). It is similar to the 3003 খাদ, প্রায় যোগ ছাড়া 1% ম্যাগনেসিয়াম. It can be cold worked (but not, unlike some other types of aluminium alloys, তাপ চিকিত্সা) 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, ভাল কর্মক্ষমতা, and good corrosion resistance. It is commonly rolled and extruded, but typically not forged. একটি পেটা খাদ হিসাবে, it is not used in casting.
3003 aluminum sheet is a very cost effective grade, 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.
দ্য 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. তাই 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.
