Description of Spherical Invar Powder
Invar, also known as FeNi36 or Invar 36, is a nickel-iron alloy with 36% nickel. Alloy 36 has an extremely low coefficient of thermal expansion (CTE) around room temperature. This means that Invar expands very little when heated, making it ideal for applications where dimensional stability is crucial.
Spherical FeNi36 powder is a finely ground form of the FeNi36 alloy, containing approximately 36% nickel and 64% iron. Invar 36 Powder is used in 3D printing, thermal coatings, and magnetic components, offering low thermal expansion and high stability.
