Supplier KMZ offers a circle, a wire, a tube made of tin bronze С90300. at economical price. Regular customers can take advantage of the discount discount. The provider ensures timely delivery of products to any email address. The price is the best in this segment of the rental.

Technical characteristics

Tin bronze brand С90300 also known as Navy G and SAE 620. The material has excellent corrosion resistance, high wear resistance and low coefficient of friction in conjugate pairs. Tin bronze is well suited for the manufacture of parts operating in conditions of high loads and relatively low sliding speeds. Tin bronze is usually supplied in the form of castings centrifugal casting, continuous casting and sand casting.

Application

Bushings, bearings, gear blanks, pump housings, valves and steam fittings, impellers pumping systems, piston rings, valves. Production gear, high strength bushing and bearing applications requiring high strength with low speeds and high loads: Tin bronze castings are used in movable components of bridge structures for stationary and extending bearings with slow or intermittent movement with heavy loads.
