Alloy Grade UNS: C95400 Aluminum Bronze

  • Overview

    C95400, also known as MTEK 175, is a high-strength aluminum bronze alloy specifically formulated for applications demanding exceptional wear resistance and compressive strength. With a composition of up to 11% aluminum, this alloy exhibits remarkable hardness and resilience, making it highly resistant to wear, abrasion, and deformation under heavy loads. It also possesses excellent antifriction qualities, minimizing friction and preventing galling or scratching in moving parts. Furthermore, the inherent antimicrobial properties of copper contribute to its suitability for applications where hygiene and cleanliness are critical. This combination of characteristics makes C95400 a valuable choice for demanding environments where durability, wear resistance, and compressive strength are essential.

  • Typical Uses

    Bushings, bearings, forming rolls and dies, gears, marine propulsion, pickling equipment, pump and valve components, seals, wear rings, and wear-resistant parts.

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.
