Alloy Grade UNS: MTEK MM247 – Nickel-based Superalloy

  • Overview

    MTEK MM247 is a nickel-based superalloy specifically formulated to deliver exceptional strength and ductility across a wide range of temperatures, including those approaching its melting point. This alloy's unique composition and microstructure provide outstanding resistance to creep, oxidation, and other forms of high-temperature degradation, making it suitable for demanding applications where components are exposed to extreme heat and stress. MTEK MM247 maintains its mechanical properties and structural integrity even under prolonged exposure to elevated temperatures, ensuring reliable performance in challenging environments. This combination of high-temperature strength, ductility, and resistance to degradation makes MTEK MM247 a valuable choice for applications in aerospace, power generation, and other industries where materials must withstand extreme conditions.

Frequently Asked Questions

Vacuum cast alloys are metals melted and poured in a vacuum environment to reduce contamination from gases and ensure high purity and precision.

Used in aerospace, medical implants, nuclear components, and high-performance turbine parts requiring precise composition and minimal inclusions.

Vacuum casting reduces gas porosity, prevents contamination, and enhances alloy quality, especially for reactive or high-performance metals.

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.
