Alloy Grade UNS: CW-6MC – Exceptional Corrosion Resistance

  • Overview

    CW-6MC, also known as N06625 in its wrought form, is a nickel-based austenitic alloy renowned for its exceptional corrosion resistance and fatigue strength, especially in demanding marine environments. This alloy exhibits high resistance to various forms of corrosion, including seawater, making it suitable for challenging offshore and coastal applications. CW-6MC also demonstrates excellent fatigue strength, ensuring reliable performance under cyclic loading conditions. Furthermore, it maintains its strength at sub-freezing temperatures and offers good high-temperature resistance, making it versatile for a wide range of operating conditions. Its ease of welding and processing further enhances its suitability for complex fabrication and integration into various systems.

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.
