Shandong Aluminum suppliers, Weifang dry Hui, a professional manufacturer, reasonable price and quality assurance. A high-strength aluminum tubes for hard aluminum, can be heat strengthened, in the annealed, hardened and thermal state just moderate plasticity, good spot welding, gas welding and welding with aluminum have a tendency when the formation of intergranular cracks; tubes after quenching and work hardening can be cutting is still good, bad in the annealed condition. Corrosion resistance is not high, often with anodized and painted method or surface plus clad layer to improve corrosion resistance. Can also be used as a mold material. Aluminum advantages: First, welding technology advantages: suitable for industrial production of thin-walled copper and aluminum pipe welding technique, known as a world-class problems, is a key technology to connect the air conditioner pipe aluminum and copper. Second, the life of advantages: from the inner wall of tubes, due to moisture-free refrigerant, aluminum connecting pipe wall corrosion will not occur. Third, energy-saving advantage: air conditioner indoor unit and outdoor unit connecting pipe, the lower the energy-transfer efficiency, or that the more power the better the insulation. Fourth, good bending performance, ease of installation, relocation benefits stem Weifang Steel and Aluminum Co., Ltd. is a company specializing in all kinds of glass doors and decorative arts business.
