Shenzhen Genting Metal Products Materials Co., Ltd. in China's largest industrial manufacturing and processing center - Shenzhen City is one of the Pearl River Delta region of Guangdong Province, a large-scale metal materials suppliers. Our main supply: copper: brass, copper, bronze, glass disabilities copper, phosphor bronze, aluminum bronze, chromium, zirconium, copper, copper, beryllium copper, tungsten, copper and the like; aluminum: Domestic Southwest Aluminum, Henan Aluminum Foshan Nanhai aluminum, imported original material in line with international standards of the United States Air AMS ALCOAINC, Russia KAMNENS / KUMZ, Sumitomo of Japan, South Korea, aluminum: rod, row, tube, strip, wire and other popular brands: 1050,1060,1100, 2017,2024,3003,5052,5083,6061,6063,6082,7075,7050 like. Lead material: lead, rods, tubes, wire, lead ingots, lead glass. Concurrently stainless steel materials, insulation materials, products widely used in metal processing, plastic molds, machinery and equipment, electrical and electronic, aviation, shipbuilding, military and other industries. Products: aluminum is a non-ferrous metal pipe, aluminum or aluminum alloy refers to extruded processed into a metal tubular material longitudinally along its full length hollow. Widely used in automobiles, ships, aerospace, aviation, electronics, agriculture, electronics, home and other industries. Characteristics of a high-strength aluminum hard aluminum, can be heat strengthened, in the annealed, hardened and thermal state just plasticity medium, good spot welding, gas welding and aluminum welding time has a tendency to crack formed between the crystal; tubes after quenching and work hardening can be cutting is still good, bad in the annealed state. Corrosion resistance is not high, often with anodized and painted or surface plus clad layer method to improve corrosion resistance. It 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 the world-class problems, is the key technology to connect the air conditioner aluminum and copper pipe. Second, the life of advantages: from the inner wall of tubes, due to the refrigerant without water, copper-aluminum connecting tube wall corrosion does not occur. Third, energy-saving advantage: air conditioner indoor unit and outdoor unit connecting pipe, the lower the energy efficiency of heat transfer efficiency, or that the more power the better the insulation. Fourth, good bending performance, easy installation and moves.
