1100 aluminum plates are mostly used in automobiles, construction and other industries. Improving the quality of aluminum products is the basis for the survival of enterprises. Aluminum materials are unstable in the air and tend to produce oxide films that are difficult to identify with the naked eye. Due to different processing methods of aluminum parts, such as casting, rolling Due to direct shearing, mechanical finishing, heat treatment or welding after forming by different processes, the surface of the workpiece will show different states, dirt or traces of varying degrees. Therefore, during the pretreatment process, the pretreatment process must be selected based on the actual conditions of the workpiece surface.
1100 aluminum plate should be paid attention to during the pretreatment process:
Not all surfaces of solid castings are machined. The untreated surface leaves an overly thick oxide layer formed during the casting process, and some surfaces leave a sand layer. At this time, the original oxide film of the part should be removed first by machining or sandblasting or alkali cleaning and post-processing. Only in this way can the original oxide layer of the unprocessed parts be prevented from being removed and processed, and changes in the tolerance dimensions of the machining position can be prevented.
The issues that should be paid attention to during the pretreatment process of 1100 aluminum plate fine workpieces are as follows:
Although the natural oxide film on the surface of fine workpieces is formed first and is easy to remove, oily workpieces, especially in and around the holes, must be cleaned with high-quality solvents. If directly cleaned with alkali, not only will it be difficult to remove the oily weight, but the weight will also be broken into pieces. The workpiece cannot withstand strong alkali corrosion for a long time, thus affecting the roughness and tolerance of the workpiece surface, and it may become waste.
1100 aluminum plate belongs to the pure aluminum plate series, with low strength, good ductility, formability, weldability and corrosion resistance. It is generally used in utensils, heat sinks, bottle caps, printing boards, building materials, heat exchanger components, and can also be used as deep stamping products. From cookware to industrial equipment, it is widely used in many fields. It has such a wide range of applications. use
