Alloy Grade UNS: C93200 Tin/Lead Alloy

  • Overview

    C93200 stands out as a popular tin/lead alloy offering a compelling combination of performance and cost-effectiveness. Its notable score resistance makes it suitable for applications where surfaces may experience sliding or abrasive contact. The alloy's structural uniformity ensures consistent properties throughout, contributing to reliable performance and predictable behavior. Furthermore, C93200 exhibits good shear properties and compressive strength, making it capable of withstanding forces applied parallel to its surface and resisting deformation under compression. This blend of characteristics, coupled with its low cost, makes C93200 an attractive option for a variety of applications where reliable performance and economic considerations are paramount.

Frequently Asked Questions

Bearing bronze is an alloy designed for low-friction, high-wear-resistance applications in machinery bearings and bushings.

Used in sleeve bearings, pump bushings, and machinery where lubrication and wear resistance are essential.

It offers low friction, good load capacity, machinability, and resistance to seizure and galling in lubricated conditions.

Bearing bronze exhibits excellent conformability, embeddability, and resistance to wear and fatigue, making it ideal for sliding contact 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.
