Definition of anodized aluminum in accordance with national standards: a process of electrolytic oxidation of 5-axis processing, the surface of the aluminum or aluminum alloy process generally translate into an oxide film, which has a protective layer of film, decorative and other The functional properties. Anodized aluminum departure from this definition to include only this part of the process to generate anodic oxide film. As the name suggests, liquid aluminum in the cell should be connected to the positive external power supply as the anode, and the cathode of the electrolytic cell was connected to the negative external power source, the applied voltage to maintain the current through the electrochemical oxidation reaction. Aluminum anodizing process in which the presence of the oxide film formed while the reaction and dissolution of two opposing surfaces of the final status of the two reaction speed depends on the relative size of the decision. 304 # stainless steel --SUS304, equivalent to China's 0Cr18Ni9. A density of 7.85 g / cc aluminum lathe processing, chemical composition (%): C≤0.15% Cr: 17 ~ 19% Si≤1.5% Mn≤2.0% S / P≤0.05% hardness 350-430HV minimum density 7.6G / CM3. Stainless steel in the surface treatment, general polishing after it, because the polishing can be very good reflect stainless steel texture. Thus processing, seal oil and electroplating Dongguan rarely used CNC lathe processing, because there is no much need. Zinc: Zinc alloy product is processed by using zinc die-casting process, therefore, by looking at the back of the product, is not easy to reverse and polished section, you will find mold India, thimble and India. Stainless steel program CNC lathe, Hong Run (Certified), processed by Hongrun Dongguan Shijie Hardware Products Factory. Hongrun Dongguan Shijie Hardware Products Factory (dghrwj1688.1688.com) is Dongguan, hardware accessories leader over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
