Alloy Grade UNS: C93700 Tin/Lead Alloys

  • Overview

    C93700 is a popular tin/lead alloy. This high lead alloy has score resistance, structural uniformity, shear properties, compressive strength, and low cost. Additionally, the lead aids in good thermal conductivity. This material holds up well in tough environments. Large bearings for ships would be an excellent use case.

  • Typical Uses

    Bearings, bushings, centrifuge bushings, gears, hydraulic parts, impellers, liners, piston rings, pump and valve components, sleeves, steam fittings.

  • MetalTek Grade

    MTEK 80-10-10

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.
