Alloy Grade UNS: C92900 Special Gear Alloy

  • Overview

    This special gear alloy is used extensively for machine tool gears, threaded worm gear nuts, or elevating nuts where there is large surface area in contact. The lead addition reduces friction and affords easier machining in addition to extending service life under adverse conditions. Also referred to as leaded nickel-tin bronze.

  • Typical Uses

    Gears, nuts, and cams.

  • MetalTek Grade

    MTEK 102-N
