C903 is a tin bronze or Navy “G” bronze alloy with good mechanical and corrosion resistance plus the added benefit of high wear resistance. The C903 alloy is comprised of 86-89% copper, 3-5% zinc, and 7.5-9% tin. C903 is commonly used to make many parts, including marine castings, bearings, bushings, pump components, valve components, gears, and steam fittings.
At Patriot Foundry & Castings, we produce high-quality sand castings using a wide assortment of materials, including the C903 alloy. Our state-of-the-art nonferrous foundry can handle jobs from one to thousands of pieces, and C903 castings from less than an ounce to 232 pounds. Aside from alloy casting, we also offer many value-added services, including pattern design/production, heat treating, annealing, machining, powder coating, painting, anodizing and assembling for completely finished parts.
We’re proud to be ISO 9001:2008 certified (Certificate No.: 11-2168). Our DUNS number is 826918117, and our CAGE Code is 54J41.
