Alloy Grade UNS: C93800 Tin/Lead Alloy

  • Overview

    C93800 is a popular tin/lead alloy. The high lead alloys have score resistance, structural uniformity, shear properties, compressive strength, corrosion resistance, and a low cost. The Nickel addition in C93800 boosts the strength and ductility. This alloy contains 78% Copper, 15% lead, and up to 15% lead. The high lead bronzes are good for bushing and bearing applications. When it comes to machinability, it scores an 80, but it does not respond to heat treatment.

  • Typical Uses

    Bearings, bushings, centrifuge bushings, gears, hydraulic parts, impellers, liners, piston rings, pump and valve components, sleeves, and steam fittings. Other typical uses include acid-resisting applications, pump impellers, railroad applications, pumps, and industrial centrifuges.

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.
