Silicon bronze(S211)

Introduction of silicon bronze A bronze with silicon as the main alloying element. Silicon bronze used in industry also contains a small amount of manganese, nickel, zinc or other elements besides silicon. Silicon is finite solid solution in copper, the maximum solubility at 852 is 5.3%, and decreases with the decrease of temperature, but the effect of aging hardening is not strong, and generally no strengthening heat treatment is carried out. The silicon content of the deformed silicon bronze is 1% to 4%. The crystalline temperature range of silicon bronze is small, it has enough fluidity, and its mechanical property is higher than that of tin bronze. It can be used as substitute for tin bronze in machinery manufacturing industry. Chemical properties Silicon bronze rods have strong corrosion resistance to the atmosphere, water, water, natural fresh water and sea water. Because the surface will form a dense and solid chloride membrane, the flow rate can not exceed 1. 5m, otherwise the oxide film will be destroyed and the protective force is lost. If the temperature is greater than 60 C or CO2 and oxygen in water, the erosion rate will accelerate. Silicon bronze rods have high corrosion resistance to alkali solutions with low concentration and low temperature. However, the increase of temperature or concentration will lead to the increase of erosion speed. The acid water containing Fe2 (SO4) 3 will produce strong erosion on the silicon bronze rod, as Fe2 (SO4) 3 has the depolarization of the cathode. Chromate, ferric chloride solution and concentrated zinc chloride solution will strongly corrode silicon bronze rods. Dry chlorine, Australia, hydrogen fluoride, hydrogen sulfide, hydrogen chloride, sulfur dioxide, ammonia, and carbon tetrachloride all do not corrode silicon bronze rods, and if they contain water, the silicon bronze rods are eroded. Acetylene, ammonium hydroxide, ammonium chloride, chromic acid, ferric chloride, iron sulfate, mercury, mercury salt, nitric acid, potassium cyanide, sodium dichromate, potassium dichromate, silver salt, sodium hydrogen chloride, molten sulphur, cyanic acid all erode silicon bronze rods.
