3003 Aluminum Application for Hollow Aluminum Strip in Insulating Glass Spacer


3003 alloy is an aluminum alloy with manganese as the main element. It has good corrosion resistance to air, fresh water, sea water, food, organic acid, gasoline, neutral inorganic salt aqueous solution, etc., so there is a reputation of "king of rust". The chemical composition of the 3003 alloy is: Si: 0.60, Fe: 0.70, Cu: 0.05-0.20, Mn: 1.0-1.5, Zn: 0.10, Other: single 0.05 and total 0.15 and Al: balance.

The strength of the 3003 alloy aluminum coil is not very high, and the slightly higher strength is mostly used for industrial pure aluminum. It cannot be heat-treated. Therefore, the cold processing is often used to improve its mechanical properties: The plasticity is high under the annealing state and it is good when semi-cold hardening, and decrease during the cold work hardening.3003 has good corrosion resistance and weldability while the machinability is poor. It is mainly used for processing parts that require good formability, high corrosion resistance, and good weldability. Such as kitchen utensils, food and chemical product processing and storage devices, tanks, various pressure vessels and pipes processing.

3003 alloy aluminum strip is one of the most necessary materials for insulating glass producing. Its quality is directly related to the use effect, service life and thermal insulation function of the insulating glass. It is applied to 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 processing steps, the surface is smooth, non-oxidized, non-corrosive and has no effect on the desiccant, which effectively eliminates the atomization phenomenon. It is a kind of new environmental friendly building material which have a broad application market.

As one of the main products of Aluminum Factory, 3003 aluminum coil enjoy smooth surface, anti-rust 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. Now 3003 aluminum coil processing technology is mature and stable and the products are sold well at home and abroad which have won the recognition and trust from worldwide customers.
