Alloy Grade UNS: C95220 – Unusually High Yield Strength

  • Overview

    C95220 is a copper-based alloy engineered for applications demanding exceptional strength and resilience. This alloy distinguishes itself by combining good tensile strength with an unusually high yield strength, meaning it can withstand significant forces without permanent deformation. Its good hardness further contributes to its ability to resist wear and indentation, while its fair elongation ensures a degree of flexibility to absorb impacts. C95220 is also known for its toughness, ability to withstand overload, and resistance to "squashing" or "peening" – types of damage caused by repeated impact. Furthermore, it offers good fatigue strength for durability under cyclic loading, good ductility for formability, good rubbing resistance for applications involving friction, and excellent corrosion resistance for longevity in harsh environments. Its good machinability and weldability make it a versatile choice for complex assemblies and intricate components.

  • Typical Uses

    It is ideal for medium to heavy gears, bushings, bearings, and worm wheel applications such as boom hoists and winches, rollers, and machine tool parts subject to shock or impact. Also used in marine propulsion, pickling equipment, pump and valve components, seals, wear rings, and wear-resistant parts.

Non-Ferrous

Non-ferrous alloys are, literally, materials that are not iron-based. While others may provide non-ferrous materials of other materials, the MetalTek family of non-ferrous alloys are copper-based. In general, these materials deliver high strength, and excellent wear and corrosion resistance. They are often found in marine applications and also bushing, bearing, and gear environments.
Stainless Steel Parts

Stainless Steel

Stainless steels owe their ability to resist corrosion primarily to the presence of a passive film on their surface. Chromium is chiefly responsible for formation of the passive film. Iron ceases to rust at approximately 12% chromium content and resistance to oxidizing corrosives increases rapidly with chromium content up to approximately 20%.

Specialty Alloys

Specialty Alloys comprise a broad group of materials that deliver properties for more demanding applications, use more exotic or expensive materials, or require special processes to manufacture. Where standard materials may not offer desired performance, specialty alloys (including those that are modified further) may be a sensible selection.
