Firewood + 10mm 1mm joint venture plywood, the kind of air box is currently the most common kind of customer contrast, the air box-like color can be arbitrary choice, offer also relatively cheap points;. Is the most information with me throughout aluminum silver-white light metal, with outstanding plasticity, high electrical conductivity and thermal conductivity, along with also has antioxidant and anti-corrosion ability. Aluminum is very simple oxidation of aluminum oxide film, simple inclusions occur in the weld, causing damage to the metal continuity and uniformity, reducing its mechanical features and resistance to corrosion. Xiongxian plastic carrying case CATIC factory since its establishment in 2003., specializing in the production of military equipment boxes, aviation equipment boxes, medical equipment boxes, Jiangsu instrumentation boxes, aluminum instrument case, welcome to order. After the damaged military equipment boxes, welding generally selection of 301 aluminum welding wire and aluminum-silicon wire 311 to left welding method, welding torch and workpiece angle of 60 °, welding thickness 15mm or more to the right welding method, welding torch and workpiece at 90 ° angle in the air aluminum oxide combined with simple to produce fine aluminum oxide film (thickness of about 0.1-0.2μm) Jiangsu instrumentation boxes, high melting point (about 2050 ℃), well beyond the melting point of aluminum and aluminum alloys (about 600 ℃ or so). alumina density 3.95-4,10g / cm3, aluminum is approximately 1.4 times, the appearance of the alumina film of easy absorption of moisture, welding, which prevents fusion of the base metal. very simple structure pores. slag, incomplete fusion and other shortcomings, resulting in reduced weld function. Hebei Aviation aluminum instrument box factory in Jiangsu instrumentation boxes, Aluminum contract Jiangsu instrumentation boxes nationwide, equipment boxes, meter boxes, aluminum box design processing business. precision instruments me, Jiangsu instrument case, the aircraft carrying case provided by Xiong Aviation aluminum instrument box factory. Xiong Aviation aluminum instrument box factory (www.lljbf.com) (www.lljbf.com) strong, credible, in Baoding kits, toolboxes and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead me in the aircraft instrument into the brilliant and you work for a better future!
