Alloy Grade UNS: C93900 Tin/Lead and High Lead Alloys

  • Overview

    C93900 is a widely used tin/lead alloy that offers a compelling combination of performance and affordability. This high-lead alloy is specifically formulated to provide excellent score resistance, meaning it can withstand sliding or abrasive contact without significant damage. The alloy's structural uniformity ensures consistent properties throughout, contributing to reliable performance and predictable behavior. Furthermore, C93900 exhibits good shear properties and compressive strength, allowing it to resist forces applied parallel to its surface and withstand compression. This blend of characteristics, coupled with its low cost, makes C93900 an attractive option for a variety of applications where durability and economic considerations are paramount.

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.
