Perfect for applications in the Aerospace industry

Alloy 36 can be used in a variety of applications, here are just a few examples:

  • Tooling and dies for composite forming
  • Cryogenic components

About Alloy 36

Alloy 36 retains incredible strength and toughness at cryogenic temperatures. It can also be hot and cold formed and is readily machined using processes similar to austenitic stainless steels. Alloy 36 is weldable using Filler Metal CF36 which is available in bare wire for both the GTAW and GMAW process.

Features of Alloy 36 include:

  • Low expansion rate up to 260°C
  • Readily weldable

This alloy has been used in a variety of markets for a wide array of applications, including tooling and dies for composite forming and cryogenic components.

FAQs & Resources

Superalloy refers to a group of iron-, cobalt- or nickel-based alloys commonly used in extremely high temperature and highly stressed conditions. Such conditions are commonly found in aircraft engines where high-performance nickel-based (most common) superalloys are subject to about 10,000 rpm and temperature as high as 2000 °C. These conditions are essential because when the engines run at higher temperature, less fuel is needed. Therefore these superalloys are always going to be in high demand and at the forefront of materials and metallurgical research field. The ‘super’ superalloys are being developed as we speak!

Nickel based alloys are alloys with nickel content from slightly less than 50% to 99.98% (Metals Handbook; Vol.7 Atlas of microstructures of industrial alloys, 8th edition). They are commonly used in high-temperature and other specialised applications.

Yes, nickel alloys are magnetic. Magnetic alloys are those that contain at least one of the following elements – iron (Fe), nickel (Ni) and cobalt (Co).

AMS materials tend to be used in the production of parts and components in the aviation and motorsport industry where the integrity of the materials is critical. AMS stands for Aerospace Material Specification in the metal industry. Aerospace Material Specification cover a wide range of alloy grades ranging from stainless steel to titanium and nickel alloys.
