Low-density aluminum alloy, high strength, high thermal conductivity of aluminum rods supply manufacturers, corrosion resistance strong aluminum rods, with good physical properties and mechanical properties, which are widely used in various industries due to improper selection of aluminum alloy welding methods rod manufacturers, resulting in deformation of aluminum alloy and other seriously affected the surface oxide film product quality and performance before welding preparation by chemical or mechanical methods, strict trimming on both sides of the mouth of the Singapore Chemical cleaning is the use of alkali or acid cleaning the surface, This method can remove the oxide film, but also in addition to oil, the specific process is as follows: volume fraction of 6% to 10% sodium hydroxide solution, at about 70 ℃ soaked 0.5min → washing → volume fraction of 15% nitric acid at room temperature and soak 1min ongoing treatment → washing → washing → drying temperature alloy surface after a good wash as dull silver. mechanical cleaning can be pneumatic or electric cutter aluminum rod stock, can be applied to the blade , rasp and other tools for thin oxide film can also be polished 0.25mm copper wire brush to clear the oxide film. cleared immediately after welding, if you place more than 4h, should be re-cleaned. First, the cooling rate shaping mold cooling Water temperature is often not taken seriously enough, cooling water is the role of macromolecular chains stretch profiles timely cooling stereotypes, achieve the purpose of use. Second, the lack of die pressure at the die pressure die size is directly affected by the compression ratio, especially is the length of the straight section of the die to determine the compression ratio is too small or die short straight sections can cause product is not dense, affecting the physical properties of aluminum alloy rods aluminum rods supply manufacturers _ _ cis Aluminum (Certified Merchant ) provided by the Aluminum Co., Ltd.
