Home  /  Lead Free Bronze Bushings

Elite Bushing is the premiere name in the niche of environmentally-friendly bearing and cast bar solutions and supplies leading producers of sustainable energy, marine, medical and other commercial products with high quality bronze bushings. Our eco-friendly alloy C87850 ECO Bronze is RoHS compliant and meets the lead-free safe drinking water act. The main difference between our ECO BRONZE and other lead-free alternatives is that ECO BRONZE is a great bushing material

Other materials compromise their bushing properties to become lead-free, but ECO BRONZE has proved to be as good as, and in some cases superior to, the leaded material it has replaced.

ECO BRONZE is probably the most tested lead-free bronze material to-date; it’s tough, non-galling, does not get brittle at high temperatures, superior impact and compressive strength, and a great bushing material. Eco Bronze has gained acceptability in the potable water pump industry as it is S3874 & AB1953 compliant, it’s also gained acceptance in other industries such as construction equipment, Wind tower, food processing, medical devices and many others due to its great bushing properties.

C89835 Bismuth Tin Bronze

“Lead Free”C89835 is a “Lead Free” alternative for C93200 Bearing Bronze. When an application requires the properties of C932 Bearing Bronze but needs to be “lead free”, C89835 Bismuth Tin Bronze can be used. C89835 Bismuth Tin Bronze utilizes Bismuth as a Lead replacement. Bismuth and Lead both have relatively low solubility in copper alloys. As such, during casting, these elements solidify into low melt point pools through the alloy matrix, filling porosity voids and providing advantages for chip breakage during machining.

Application :

  • Pipe Fittings
  • Pump Components
  • Water Pump Impellers
  • Housings

C90300 (SAE620) Navy G Bronze / C903 High Tin Bronze

C90300 SAE 620 Tin Bronze is often used in high load, low speed applications. C903 Bronze has excellent wear properties. As the name may imply “Navy G” bronze is used in various marine applications due to its excellent resistance to corrosion. A member of the High Tin Bronze Alloy family C90300 Bronze is used in similar ways as the other alloys of this family.

Tin bronze alloys, such as C903, are typically found in gear, high-strength bushing and bearing applications where high strength and low speeds and heavy loads are present. Other high-strength applications for these alloys are pump impellers, piston rings, steam fittings and valve bodies. C90300 tin bronze castings are utilized in movable bridge components, turntables for bridges and other structures for fixed and expansion bearings with slow or intermittent movement with heavy loads.

  • Gears
  • Worm Gears
  • Valves
  • Seal Rings
  • Pump Impellers
  • Valve Bodies
  • Bushings
