Alloy Grade UNS: BEARIUM® B-10 – Leaded bronzes 

  • Overview

    Bearium B-10 is a leaded bronze alloy known for its excellent friction properties, thanks to a finely dispersed microstructure. While it has lower tensile strength compared to other alloys, it excels in wear resistance and hardness, making it ideal for high-performance applications. This alloy is perfect for components like bearings, bushings, and thrust washers, especially in environments with limited lubrication. Bearium B-10 can handle shock loads and is recommended for use with harder mating shafts, such as those that are heat-treated or carburized. It's an excellent choice for demanding applications like turbine thrust bearings.

  • Typical Uses

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.

Its microstructure combines tin, lead, and copper phases that resist deformation under heavy loading, making it ideal for high-pressure bearings.

Compared to other bronzes, Bearium B-10 offers better impact resistance, lower friction coefficients, and longer service life in high-load conditions.

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.
