Alloy Grade UNS: C94300 High Lead Alloy

  • Overview

    C94300 is a high-lead alloy prized for its exceptional performance in demanding applications. Its significant lead content contributes to outstanding score resistance, allowing it to withstand sliding or abrasive contact without suffering significant damage. This alloy also exhibits structural uniformity, ensuring consistent properties throughout the material and promoting predictable behavior. Furthermore, C94300 demonstrates good shear properties and compressive strength, enabling it to resist forces applied parallel to its surface and withstand compression. This combination of characteristics, along with its cost-effectiveness, makes C94300 a popular choice for applications where durability, reliability, and budget are key considerations.

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.
