A true titanium alloy, ALLVAR Alloy 30 is lightweight, corrosion resistant, non-magnetic, and machinable. ALLVAR Alloys are the only metals in the world that shrink when heated and expand when cooled. Known for their Negative Thermal Expansion (NTE) properties, ALLVAR Alloy 30’s revolutionary properties enable otherwise unachievable passive athermalization in a variety of applications. Current applications include refractive and reflective optics and constant force load fasteners. |
