Alloy Grade UNS: CL I TYPE A – Wear Resistant Alloy

  • Overview

    CL I Type A, also known as MTEK 80 or white iron, is a wear-resistant alloy renowned for its exceptional hardness and durability. This alloy typically contains up to 5% nickel and 4% chromium, with the chromium addition enhancing its corrosion and oxidation resistance. Its high hardness makes it exceptionally resistant to wear, abrasion, and erosion, making it suitable for applications involving sliding contact, impact, and exposure to harsh environments. CL I Type A is a valuable choice for components requiring long-term wear resistance and dimensional stability in demanding 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%.

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.
