Alloy Grade UNS: C93500 Tin/Lead Alloys

  • Overview

    C93500 is a widely used copper-tin-lead alloy prized for its balanced blend of performance and affordability. Its high lead content contributes significantly to its score resistance, ensuring durability in applications involving sliding or abrasive contact. The alloy's structural uniformity guarantees consistent properties throughout, promoting predictable behavior and reliable performance. Furthermore, C93500 exhibits good shear properties and compressive strength, enabling it to withstand forces applied parallel to its surface and resist deformation under pressure. This combination of characteristics, coupled with its relatively low cost, makes C93500 an attractive choice for a wide range of applications.

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.
