Bronze generally has a substantial increase in strength due to the addition of certain alloying elements to the copper, while obtaining certain special properties. Bronze has a relatively large deformation resistance, which brings some difficulties to CNC machining; but at the same time, it gives copper some specific functions, such as high elasticity, softening resistance, high corrosion resistance, high wear resistance and so on. As a result, the application field of copper has been greatly expanded and has become the support of new technologies.

Uses of silicon bronze
It is mainly used to make various elastic elements and parts that work under corrosive conditions, as well as wear-resistant parts such as worm gears, worms, gears, bushings, brake pins and rods. The aviation industry is mainly used as elastic components and high-strength small structural parts, such as support, rods, shafts, spring rings, etc. for combined airspeed indicators, speedometers and altimeters. Strong cold deformation leads to anisotropy of the elastic properties of the material, so when using it as an elastic element, attention should be paid to the direction of the material and the low-temperature annealing of the element.
