Alloy Grade UNS: MTEK 325 – Aluminum and Iron

  • Overview

    MTEK 325 is a high-performance aluminum bronze alloy specifically formulated with increased aluminum and iron content to achieve exceptional hardness and wear resistance. This alloy excels in applications requiring resistance to abrasion and deformation, particularly in processes involving the forming and drawing of stainless steel. Its high tensile and compressive strength ensures structural integrity and resistance to deformation under load, while its superior wear resistance minimizes damage and prolongs component life in demanding environments. This combination of properties makes MTEK 325 a valuable choice for applications where hardness, strength, and wear resistance are critical.

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.
