Alloy Grade UNS: C95520 – Highly Flexible Alloys

  • Overview

    C955220, also known as AMS 4881, is a high-strength nickel-aluminum bronze alloy specifically engineered for demanding applications where a combination of strength, flexibility, and corrosion resistance is paramount. This alloy boasts a composition of approximately 11% aluminum, 5.1% nickel, and 4.7% iron, contributing to its impressive mechanical properties. C955220 exhibits strength comparable to steel while retaining the superior corrosion resistance characteristic of bronze alloys. Its high flexibility ensures excellent conformability and resistance to cracking under stress, while its outstanding wear and galling resistance guarantees long-lasting performance in applications involving friction and sliding contact. This unique blend of attributes makes C955220 a valuable choice for challenging environments where durability, strength, and corrosion resistance are critical.
