3003 aluminum coil


3003 alloy is an aluminum alloy with manganese as the main alloying element. It has good corrosion resistance to atmospheric, fresh water, sea water, food, organic acid, gasoline, neutral inorganic salt aqueous solution, etc., and corrosion resistance in dilute acid. Very good, so there is a reputation of "king of rust".

The chemical composition of the 3003 alloy is: silicon Si: 0.60 iron Fe: 0.70 copper Cu: 0.05-0.20 manganese Mn: 1.0-1.5 zinc Zn: 0.10 Other: single 0.05, total 0.15 aluminum Al: balance.

The strength of the 3003 aluminum coil is not high, and the strength is slightly higher. It is used in industrial pure aluminum and cannot be heat-treated. Therefore, cold working is often used to improve its mechanical properties: high plasticity in the annealed state and plasticity in the semi-cold hardening. It is still good, the plasticity is low during cold work hardening, the corrosion resistance is good, the weldability is good, and the machinability is poor. It is mainly used for processing parts parts that require good formability, high corrosion resistance, and good weldability. Such as kitchen utensils, food and chemical product processing and storage devices, tanks, tanks for transporting liquid products, various pressure vessels and pipes processed with thin sheets.

3003 aluminum coil hollow aluminum strip is one of the necessary materials for the production of insulating glass. Its quality is directly related to the use effect of insulating glass, service life and thermal insulation function. Its main function is to play a role of evenly separating two or more pieces of glass in the insulating glass to effectively support. The hollow glass strip is made of high-purity aluminum as raw material. After dozens of processes, the surface is smooth and smooth, non-oxidized, non-corrosive, has no effect on the desiccant, and effectively eliminates the atomization phenomenon. The new environmentally friendly building materials have a broad application market.

As one of the main products of Henan Mingtai Aluminum, 3003 aluminum coil has smooth surface, rust-proof and high anti-corrosion brightness. The surface of aluminum strip has uniform pore penetration, good straightness, no deformation, stable size and high toughness. Well, it can be continuously bent into an aluminum frame at any angle with the bending equipment. 3003 aluminum coil has matured and matured in more than ten years. The products are sold well in China and exported to overseas, winning the recognition and trust of new and old customers.

Mingtai is a large-scale modern aluminum processing enterprise, mainly engaged in the production and sales of 1-8 series aluminum coils, aluminum foils and aluminum sheets. For more information about aluminum coils, please pay attention to our website:
