Phosphorus Bronze is a tough alloy characterized by high strength, low coefficient of friction and fine grain structure. Typical formulations for this alloy, which is also called Phosphor Bronze, contain primarily Copper with 0.5 to 11 percent Tin and 0.01 to 0.35 percent Phosphorus. Tin increases corrosion resistance and strength, while Phosphorus improves wear resistance and stiffness.
Fotofab proudly services the US & International customers.
Fotofab utilizes a chemical etching process to produce designs that can withstand harsh indoor and outdoor environments. The etching process uses an acid (Ferric Chloride) to cut into unprotected parts of a metal surface to create a design or image. Our etched projects can be machined and formed to your project’s specifications.
