Aluminum Alloy Shell CNC Processing Surface Treatment Method

With the development of science and technology, people put forward a variety of new requirements for the surface performance and appearance of CNC processing of aluminum alloy shell, such as in the aluminum alloy shell CNC processing products in large areas of the use of electroplating, people increasingly hate the luminescent plating luster, to love smoke-like tones, as well as satin-like plain tones. As a result, an electroplating alloy has been developed. Here is a brief introduction to several decorative electroplating alloys used in product finishes.

1. Aluminum alloy shell CNC processing tin-cobalt alloy.

The plating tin cobalt alloy is relatively close to the tone of electroplating cobalt, but it is softer and more popular. At present, most foreign countries are used instead of chromium. Electroplated cobalt is not easy to roll, while electroplated tin-cobalt alloy can be applied to the rolling plating of small parts. In addition, the tin-cobalt-cobalt alloy has excellent both coating and rolling capacity, making it suitable for workpieces in complex shapes. If plated on the ground floor double nickel, it is no less resistant to corrosion than chrome plating. To prevent surface discoloration, the application of impregnated chromate is treated to improve its corrosion resistance.

Its appearance is light rose tone, makes people feel very good, and has excellent corrosion resistance. A good glossy surface can be obtained if a shiny substrate is applied to a shiny substrate or on a bright nickel plating plate, and then a tin-nickel alloy plating is applied. If the matte surface (pear print) is electroplated, the original condition of the surface can occur. The electroplating capacity of the plating layer is excellent, almost completely without the flat effect, so it is suitable for plating requiring very fine lines and rotating processed products.

2. Aluminum alloy CNC processing electroplating copper-tin alloy.

The low tin bronze coating of the aluminum alloy shell is pink or gold yin, crystalline, it has high corrosion resistance and good transbolic light performance, often used as a protective -decorative nickel floor, used in light industry, handicrafts, mechanical instrumentation industry and other industries. The color of the medium tin bronze coating is golden and yellow, and the corrosion resistance is better. Mainly used as decorative chrome-plated bottom. The hardness and stability of aluminum alloy processing is higher than that of low tin bronze plating. However, due to the high tin content of the coating, as a protective decorative coating of the bottom layer after the set of chromium easy to flower, which is the weakness of the mid-tin bronze coating. High-tin bronze coating has a beautiful silver-white luster and good spin-ray performance, has a high hardness and wear resistance, in industrial design to replace silver or chromium as reflective instruments, instrumentation, daily commodities and other protection - decorative surface coating.
