Alloy Grade UNS: CW-2M – Extreme Heat

  • Overview

    CW-2M represents a family of nickel-based superalloys specifically engineered to withstand extreme heat and corrosive environments. These alloys are designed to maintain their strength and structural integrity at elevated temperatures, making them suitable for applications where components are exposed to extreme heat, thermal cycling, and corrosive elements. CW-2M alloys resist oxidation, creep, and other forms of high-temperature degradation, ensuring long-term performance and reliability in demanding conditions. Their ability to withstand extreme heat and corrosion makes them valuable choices for applications in industries such as aerospace, power generation, and chemical processing, where components must operate reliably under extreme conditions.

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.
