Emerging stainless steel metal speaker net. Like the metal speaker mesh made of aluminum alloy, the metal speaker mesh made of stainless steel can also be used to etch a complicated pattern of mesh arrangement. The mesh size is only limited by the minimum, depending on the use of stainless steel substrate The thickness of the board is 0.5mm thick and 0.6mm thick. At present, European-based OEMs, such as Daimler Benz and BMW series, use stainless steel as the mainstream. The stainless steel grade selected by the European system is 1.4301. The North American business mainly uses ASTM304, and the domestic business mainly chooses Baosteel-made 0Cr18Ni9 or Japanese JIS SUS304 is used as a substitute. In addition, the optional surface treatment methods of the stainless steel metal speaker net are very wide. The traditional methods of spray painting, powder spraying, and electrophoretic paint can be used. At the same time, the PVD surface treatment process, that is, the physical sputtering plating process can be used. The process can achieve the diversification of surface color and color. In addition, stainless steel has good ductility and moderate strength, which satisfies the feasibility of process processing, and has a certain guarantee for the performance of parts. Through the combination of stamping and forming processes, some slightly complex curved metal speaker mesh shapes can be developed.
