About Alloy 42

NeoNickel supplies Alloy 42 in accordance to the ASTM-F-1684 specification and is manufactured for industrial applications where a low Coefficient of Thermal Expansion (CTE) is required over a range of temperatures. The constraints of the specifications limit the Sulphur and Phosphorus content of the material for increased weldability.

Features of Alloy 42 include:

  • Low Expansion Rate up to 300°C
  • Readily Weldable
  • Easily Machined
  • Ideal for Composite Tooling
