Alloy Grade UNS: N19909 – Nickel Based Vacuum Cast Alloy 

  • Overview

    N19909 is a nickel-based superalloy specifically engineered for demanding high-temperature applications. This vacuum-cast alloy exhibits exceptional strength and resistance to creep at elevated temperatures, making it suitable for components that must withstand extreme heat and stress. Its high-temperature capabilities are attributed to its unique composition and microstructure, which provide exceptional stability and resist deformation even under prolonged exposure to extreme conditions. N19909 is often used in critical applications such as gas turbine blades and discs, where its high rupture strength and tensile properties at high temperatures are essential for reliable performance.

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.
