Alloy Grade UNS: C95800 – Highly Flexible Alloys

  • Overview

    C95800 is a high-strength alloy that has the strength of steel plus good corrosion resistance. It is considered a highly flexible alloy and is also called MTEK 230-N. These highly flexible alloys yield outstanding wear and galling resistance. This aluminum bronze alloy can be heat treated to improve mechanical properties.

  • Typical Uses

    Aircraft bearings, bushings, desalination components, fittings, gears, marine propulsion, pump and valve components, wear rings.

  • MetalTek Grade
