Silicon bronze bar has low concentration of alkali solution and high temperature resistance. In dilute sulfuric acid, hydrochloric acid, acetic acid, citric acid solution is not random, but the increase of temperature or concentration will lead to erosion rate rise, containing Fe2 (SO4) 3 acid water will produce a strong erosion of silicon bronze bar, because Fe2 (SO4) 3 with catholic depolarization. Chromate, ferric chloride solution and concentration of zinc chloride solution strongly eroded silicon bronze bar. Dry chlorine, Macao, hydrogen fluoride, hydrogen sulfide, hydrogen chloride, sulfur dioxide, ammonia and carbon tetrachloride were not eroded silicon bronze bar, which contains water vapor, if the silicon bronze bar. Erosion of acetylene, ammonium hydroxide, ammonium chloride, nitrate dumplings, chromic acid, ferric chloride, ferric sulfate, mercury, mercury salt, nitrate, potassium cyanide, sodium hydride, hydrogen halide, potassium dichromate, sodium chloride, molten sulfur, acid will erode silicon bronze bar.

The silicon bronze bar mainly for the production of various elastic elements and under corrosion condition part and worm gear, worm, gear, bushing, a brake pin and rod wear parts. Aviation industry is mainly used as elastic element and high strength of small structural parts, such as combination of airspeed, lifting speed and height table support, rod, a shaft, a spring ring. Severe cold deformation leads to the anisotropy of the elastic properties of the material and therefore on the elastic element, low temperature annealing of the element and paid to selected material.
