Alloy Grade UNS: CW-12MW – Superalloy

  • Overview

    CW-12MW, also known as N30002, is a nickel-based superalloy specifically formulated to provide exceptional corrosion resistance across a wide range of demanding applications. This alloy's high chromium content contributes to its ability to withstand various forms of corrosion, including oxidation, pitting, and crevice corrosion, in both high-temperature and corrosive environments. In addition to its excellent corrosion resistance, CW-12MW offers good weldability and castability, making it suitable for complex fabrication and the production of intricate components. This combination of properties makes CW-12MW a valuable choice for applications in aerospace, chemical processing, and other industries where high-temperature strength and corrosion resistance are essential.

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.
