Alloy Grade UNS: C95800 – Highly Flexible Alloys

  • Overview

    C95800, also known as MTEK 230-N, is a high-strength aluminum bronze alloy that offers a unique combination of strength, flexibility, and corrosion resistance. This alloy exhibits strength comparable to steel while maintaining the inherent corrosion resistance of bronze alloys, making it suitable for demanding environments. Its high flexibility ensures excellent conformability and resistance to cracking under stress, while its outstanding wear and galling resistance guarantees long-lasting performance in applications involving friction and sliding contact. Furthermore, C95800 can be heat-treated to further enhance its mechanical properties, tailoring it for specific applications where even greater strength or wear resistance is required. This combination of attributes makes C95800 a valuable choice for challenging applications where a balance of strength, flexibility, corrosion resistance, and wear resistance is crucial.

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.
