Since the first human use of power devices to go to heaven in 1903, the development of aerospace vehicles has been inextricably bound up with the development of aluminum alloy materials. The engine block of the Wright Brothers aircraft (Wiright Flyer1) is made of 8% copper aluminum alloy.
High-speed railways play a vital role in the transportation of countries around the world. In recent years, the development of high-speed railways has attracted more attention from the public, and the raw materials for manufacturing high-speed trains have also undergone tremendous changes.Aluminum alloy car body has the advantages of light weight, corrosion resistance, good flatness and easy to manufacture complex and beautiful curved car body, so it is welcomed by urban transportation companies and railway transportation departments in the world.
The position of aluminum alloys in various industries has been increasing year by year, and the scope of use of aluminum alloys has become more and more extensive, not only for high-speed rail applications in aircraft manufacturing, precision molds, electronic parts, machinery manufacturing, communications equipment, electronic product machining, and transportation. Now, in the area of maritime transport-the application of shipbuilding is also more extensive.
Some time ago, the PTJ’s expert team gave you a rough introduction to the advantages of imported aluminum alloys in the automotive manufacturing field. Many careful industry professionals have carefully browsed our website and called to ask us: which brand of material is more suitable for application. What about automotive machining?
Although the aluminum alloy composition and heat treatment have greatly improved the performance of aluminum alloys, in many cases it is also required that the aluminum alloy surface has special properties such as wear resistance and corrosion resistance, and most of the failure of aluminum alloy materials starts from the surface, so It is particularly important to improve the surface properties of materials. Surface treatment can improve protection, decoration and functionality, overcome the shortcomings of aluminum alloy surface performance, expand the scope of application, and extend the service life.
The main alloying elements of 6061 alloy are magnesium and silicon, which is one of the most widely used aluminum alloys. It has medium strength, good corrosion resistance, and good oxidation effect, especially the alloy has an excellent response to hard oxidation. 6061 aluminum plate is widely used after heat treatment, and 6061 aluminum alloy thick plate is used in semiconductors, automated mechanical parts, precision machining, various mold manufacturing, fixtures and so on.
Recently, some customers called to inquire about hard oxidation related issues. Today, PTJ used their leisure time to talk to friends carefully.
Many new friends who are involved in the field of oxidation will encounter the problem of poor oxidation effect. Today, the experts of PTJ will talk to you about the reasons that may lead to the unsatisfactory oxidation effect. Talk about the various factors that lead to the unsatisfactory oxidation effect.
