Alloy Grade UNS: C91600 – High Tin Bronze

  • Overview

    C91600, also called high tin bronze, is a copper-tin alloy with high strength and hardness. It resists wear and corrosion, performing well under heavy loads and slow speeds. The high tin content (14-16%) is what gives this alloy its "high tin bronze" designation. C91600 is often used in demanding environments due to its durability.

  • Typical Uses

    Bearings, bushings, pump components, gears, and fittings.

  • MetalTek Grade

    MTEK 65+Ni

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.
