Is a high-strength aluminum hard, can be heat strengthened, in the annealed, just quenching and thermal conductivity of aluminum Shandong moderate plasticity state ranked supplier, good spot welding, gas welding and welding aluminum when there is formation of grain Intention crack; 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, the general characteristics of aluminum shift: aluminum and aluminum alloy with unique physical and chemical properties. It was a silver-gray appearance, density, small resistivity, linear expansion coefficient. Because aluminum is face-centered cubic structure, no change allotrope conductive aluminum row, no "extension - brittle" change, which has excellent low-temperature toughness conducting professional manufacturer of aluminum row, at low temperatures to maintain good mechanical properties. In addition, aluminum and aluminum alloy also has excellent corrosion resistance and high specific strength (strength / density), have good heat and light reflectivity. No grinding sparks and non-magnetic. Conductive aluminum row of professional manufacturers | conductive aluminum row | rolls provided by Alcoa Aluminum Co., Ltd. Jinan rolls. Jinan Heshun Aluminum Co. (www.jnhsly.com) strong, credible, in Jinan, Shandong aluminum products industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead rolls in aluminum and you hand into the brilliant, for a better future!
