Alloy Grade UNS: C97800 – Leaded Nickel Bronze Alloy

  • Overview

    C97800, commonly referred to as leaded nickel bronze, is a specialized copper-nickel-tin alloy known for its enhanced corrosion resistance and machinability. The addition of nickel contributes to its resistance against various corrosive elements, making it suitable for challenging environments. Furthermore, the presence of lead enhances its machinability, allowing for efficient and precise fabrication of components. C97800 also exhibits good strength and wear resistance, making it suitable for applications where components are subjected to moderate stress and friction. Its combination of corrosion resistance, machinability, and mechanical properties makes it a valuable choice for diverse applications requiring a balance of performance and ease of fabrication.

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.
