Alloy Grade UNS: C86500 – Copper-Zinc Alloys

  • Overview

    C86500, also known as C12A, is a high-strength copper-zinc alloy designed for applications requiring a balance of strength, corrosion resistance, and performance under dynamic loads. This alloy exhibits good strength and hardness, making it suitable for components that experience wear and tear. While its tensile strength is relatively lower compared to other high-strength brasses, C86500 offers good corrosion resistance, protecting it from degradation in various environments. Its ability to perform well under high speeds and loads makes it a valuable choice for applications involving dynamic forces and motion. This combination of properties makes C86500 a suitable option for a range of applications where a balance of strength, corrosion resistance, and dynamic performance is required.

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.
