Bronze 907 Rectangular Bar 3" x 3/4" Retail Price

About 907|Tin bronze (89% copper, 11% tin). The highest tin content in the common tin bronze series. Maximum wear resistance and hardness among the tin bronzes, making it ideal for heavy-duty gears and worm wheels. The high tin content gives excellent resistance to saltwater corrosion. Used in marine propulsion gears, heavy industrial bearings, and pump components where maximum wear life is required. Harder to machine than lower-tin alloys but manageable with carbide. Compare to C905 (slightly less tin, slightly easier to machine) and C954 aluminum bronze (different alloy system, higher strength).

About Rectangular Bar|Solid rectangular cross-section stock. Functionally similar to flat bar but typically available in thicker, chunkier profiles. The naming varies by supplier — what one calls rectangular bar, another calls flat bar. Used for keys, gibs, wear strips, brackets, and any part where a rectangular starting profile saves setup time versus milling from plate.
