Alloy Grade UNS: BEARIUM® B-8 – Leaded Bronzes

  • Overview

    A high-performance leaded bronze alloy known for its excellent friction-reducing properties. Designed for applications that demand low friction and high wear resistance, BEARIUM® B-8 delivers outstanding performance due to its carefully engineered microstructure. The alloy's components are evenly distributed throughout, ensuring consistent friction behavior across the surface for reliable and predictable results. The lead content in BEARIUM® B-8 acts as a solid lubricant, further reducing friction. This makes it an ideal choice for bearings, bushings, and other mechanical components where minimizing friction and maximizing durability are crucial.

  • Typical Uses

    Bearings, bushings, cryogenic components, pump and valve components, shaft sleeves, turbine thrust bearings, wear rings.

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.
