We are the manufacturer of Silicon Bronze Casting. We have earned the reputation for designing and manufacturing high quality silicon bronze sand castings for industrial applications. Silicon bronze is a low-lead brass alloy that is generally composed of 96 percent copper. The remainder can be made from silicon and a variety of other alloys such as manganese, tin, iron, or zinc. Silicon Bronze is known for its easy pouring ability, appealing surface finish and superior corrosion resistant properties, even when submerged in liquids and chemicals. Silicon Bronze was originally developed for the chemical industry but later expanded due to its good casting characteristics. Cast parts manufactured using silicon bronze are used for high wear, high load, low abrasion parts such as ball bearings, bearing cages, raceways, spacers, gears, and valve parts. They are used for machinery, aerospace, heavy equipment, and hydraulic equipment applications.
