Alloy Grade UNS: C81500 – Chromium Copper

  • Overview

    C86300 is a high-strength and hardness copper-zinc alloy. It offers a tensile strength of around 760 Mpa, which is slightly better than the C86200 alloy. This alloy excels in heavy-load applications with slow speeds. It contains 63% copper, 5% Aluminum, and 25% zinc. It has a melting point of 1693 degrees Fahrenheit. C86300 is strong corrosion resistance and wear resistance. Thermal and electrical conductivity are also highly rated.

  • Typical Uses

    Cams, fittings, flanges, forming rolls and dies, ordnance parts, shaft sleeves, steel mill nuts, worm gears. Other typical uses include hydraulic cylinder parts, heavy load bearings, hooks, large valve stems, struts, and rudders.

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.
