The most commonly used grades are C93200 (bearing bronze), C95400 (aluminum bronze), and C65500 (silicon bronze)—each offering different levels of wear resistance, strength, and corrosion performance.

Bronze machines cleanly and consistently, allowing us to achieve ±0.01–0.02 mm, and in some cases ±0.01 mm or better depending on part geometry.

Bronze has excellent self-lubricating properties, high wear resistance, and stable friction behavior, making it ideal for bushings, bearings, gears, and sliding parts.

Yes. Bronze supports polishing, mirror finishing, bead blasting, brushing, plating, and protective coatings such as tin or nickel.

Yes—especially C65500 and C95400, which offer outstanding corrosion resistance for marine hardware and chemical environments.

Absolutely. Bronze’s machinability makes it ideal for large-batch production with stable quality and low tool wear.

Industrial machinery, marine, aerospace, oil & gas, hydraulics, automotive, and robotics.

Prototypes typically ship in 5–10 days, depending on complexity and finishing requirements.
