INVAR (36) (1.3912)
Extremely low thermal expansion at room temperatures realizing dimensional stability for all kinds of applications.
Invar, a magnificent alloy discovered in 1896, is the oldest of all nickel and cobalt based alloys. Main property is the extremely low thermal expansion at room temperatures realizing dimensional stability for all kinds of applications. PHYNICX has developed a low carbon enhanced grade of INVAR (SUPERIOR) with even lower CTE than in general. PHYNICX INVAR is melted generally under vacuum.
