Invar® Spherical Powder

Invar® Spherical Powder is a nickel-iron alloy in a choice of 11 variations. It has a low thermal expansion that makes it ideal for precision instruments. This is because, with it having minimal thermal expansion and contraction, Invar® maintains precise dimensions. Example applications include precision optics mounts, semiconductor production equipment, and aerospace components where thermal stability is critical. Our Invar® Spherical Powder range enables designers to 3D print or sinter parts with exceptional dimensional control.
