Alloy Grade UNS: CU5MCuC – Nickel Steel Alloy 

  • Overview

    CU5MCuC, also known as N08825 in its wrought form, is a high-performance nickel steel alloy specifically engineered for exceptional corrosion resistance in aggressive environments. This alloy boasts a high nickel content (up to 44%) and a significant chromium content (up to 23.5%), contributing to its remarkable resistance to various forms of corrosion, including stress-corrosion cracking, pitting, and crevice corrosion. CU5MCuC is particularly well-suited for handling acids and other harsh chemicals, making it a valuable choice for demanding applications in chemical processing, marine environments, and other industries where superior corrosion resistance is critical.

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%.
Petrochemical Fittings

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.
