SWP Adjustable Coil Springs Copper Steel Wire For Hardware
Compression spring is under axial pressure of the spiral spring, can withstand the pressure, both ends can be open or closed or round flat or smooth, materials used in the cross section is round more, it is also useful for rectangular and multi-strand steel rolled a travelling.
springs have a pitch and defect, such as the shape of the compression spring are: cylindrical, conical, convex and concave, and a small amount of noncircular and the variation of various end, All products need to be shaped in accordance with the design, etc.
1, there are many surface protection treatment methods of compression spring. Generally, metal protection is obtained by electroplating. Electroplating not only protects the spring from corrosion, but also improves the appearance of the compression spring. Some electroplating metal can also improve the performance of the compression spring, such as improving the surface hardness, increase wear resistance, improve thermal stability, prevent radiation corrosion. However, if only to prevent compression spring corrosion, generally should choose galvanized layer or cadmium layer.
2. The thickness of zinc and cadmium coating determines the protection ability. The thickness is generally selected according to the working environment. The hardness of galvanized layer is recommended to be selected within the range of 6~24μm. It is recommended to select the thickness of cadmium coating in the range of 6~12μm. General pressure spring galvanized layer passivation, passivation can improve the protective performance of the coating, increase the surface appearance. In the ocean or high temperature atmosphere, as well as in contact with the sea water compression spring, the pressure spring used in 70°C hot water is stable cadmium, corrosion resistance.
3, cadmium coating than zinc coating bright and beautiful, soft texture, plastic than zinc, hydrogen brittleness is small, the most suitable for compression spring as a protective layer. However, cadmium is rare and expensive. Cadmium salt is highly toxic and seriously polluting the environment. Therefore, use is limited. Therefore, cadmium coating is only used for compression springs used in the aviation, Marine and electronics industries.
