Alloy Grade UNS: C92900 Special Gear Alloy

  • Overview

    C92900, also known as leaded nickel-tin bronze, is a specialized copper alloy meticulously engineered for gear applications where high load-bearing capacity and smooth operation are paramount. The addition of lead to this formulation not only reduces friction, contributing to extended service life and improved efficiency, but also enhances machinability, allowing for the precise and cost-effective production of intricate gear components. This unique combination of properties makes C92900 a preferred choice for demanding gear applications where durability, smooth operation, and precise manufacturing are critical factors.

Frequently Asked Questions

Gear bronze is a high-strength bronze alloy formulated for high-load applications in gears, bushings, and heavy machinery components.

Used in worm gears, bushings, bearings, and wear plates in industrial and marine environments requiring high load-bearing performance.

It offers high wear resistance, excellent machinability, and superior strength, making it ideal for high-stress, high-friction components.

Compared to phosphor or aluminum bronze, gear bronze has better load-carrying capacity and wear performance, especially in heavy-duty gear systems.

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.
