1, the working area is too large, the operation is too large swings in the slot, with the edge and center of the touch of a solution of aluminum grain supply manufacturers, updating exchange a big difference, and then the oxide film produced in color inconsistencies. Prevention approach : oxidation of the workpiece rotation and downs of small, quiet disposition can supply aluminum grain prices, but when the temperature is too low, the solution is prone to map-like piebald, two seem unnatural, processed aluminum coil coating layer is damaged portion is cut off. quality aluminum outer wear manufacturers supply aluminum particles, the inner layer is a hybrid aluminum, due to the difference between the larger, and therefore will have a "vitiligo" like spots after 3 oxidation process operating problems: alkaline etching disposal workpiece is not complete, original part of the oxide film, the dirt is not divisible; disposed of immediately after alkaline etching light on the surface is still alkaline; workpiece in the transfer process of contacting foreign body cold rod is mainly used in high demand and corrosion resistance. high formability occasion, but do not ask this kind of strength aluminum alloy. it is particularly suitable for use in chemical equipment, railway tanker also conductive material and instrumentation, materials, welding, etc. relatively infrequently in life is seen in this 3003 aluminum alloy is mainly used for processing, they still forming a part of the pressure, but require good formability, and has a very high corrosion resistance, or good weldability parts, usually used in transport liquid tank and tank pressure tank and storage devices as well as aluminum grain supply prices, aluminum particles, rolls Aluminum (View) provided by Jinan Heshun Aluminium Limited. Jinan Heshun Aluminum Co. (www.jnhsly.com) is a professional, "aluminum, aluminum, aluminum, aluminum rod, aluminum row, aluminum, aluminum, aluminum elbow" of the company. Since its inception, we adhere to the "good faith, sound management" approach, the courage to participate in healthy competition in the market, so that the "aluminum, aluminum, aluminum, aluminum coil, aluminum rod" brand has a good reputation. We adhere to the "service first, customers first" principle, so that cis Alcoa won the trust of customers in all aluminum products, and establish a good corporate image.
