Alloy Grade UNS: R30006 – Non-Galling High Temp Alloy

  • Overview

    R30006 is a cobalt-based superalloy specifically engineered for demanding high-temperature applications where resistance to galling and thermal shock are critical. This alloy excels in environments with extreme heat and rapid temperature changes, maintaining its structural integrity and mechanical properties even under challenging conditions. Its cobalt base provides a foundation of high strength and wear resistance, while the alloy's specific composition imparts exceptional resistance to galling, a form of wear caused by adhesive friction between sliding surfaces. Furthermore, R30006 offers good corrosion resistance, making it suitable for a variety of harsh environments. This combination of properties makes R30006 a valuable choice for applications in aerospace, gas turbines, and other high-temperature industries where components must withstand extreme heat, thermal cycling, and wear.

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.
