Alloy Grade UNS: MTEK X-45 – Non-Galling High Temp Alloy

  • Overview

    MTEK X-45 is a specialized high-temperature alloy specifically engineered to resist galling and withstand extreme thermal conditions. This alloy exhibits exceptional resistance to galling, a form of wear caused by adhesive friction between sliding surfaces, making it suitable for applications where components experience high contact pressures and relative motion. Furthermore, MTEK X-45 offers excellent heat and thermal shock resistance, allowing it to maintain its structural integrity and performance even under rapid temperature changes and exposure to extreme heat. This combination of properties makes MTEK X-45 a valuable choice for demanding applications where galling resistance and thermal stability are critical.

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.
