Alloy Grade UNS: C84400 – High aqueous

  • Overview

    C84400 is a widely used semi-red brass alloy that strikes an advantageous balance between performance and cost-effectiveness. This alloy boasts high resistance to corrosion in both aqueous and atmospheric environments, making it suitable for applications exposed to moisture and weathering. Its 80% copper content contributes not only to its corrosion resistance but also to its good thermal conductivity, enabling efficient heat transfer. While offering moderate strength and electrical conductivity, C84400 remains a popular choice due to its versatility and affordability. This combination of properties makes it a practical solution for a wide range of applications where corrosion resistance, thermal conductivity, and cost-effectiveness are important considerations.

  • Typical Uses

    Bearings, bushings, electric terminal ends, impellers, pipe fittings, pump and valve components.

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.
