Thermostat metals are two or more metals with different coefficients of expansion that are bonded together and change curvature in reaction to temperature changes. As formed parts or snap acting disks this movement is used to make and break circuits, indicate or compensate for temperature changes, release springs, open or close valves and perform many other tasks. Production of these high performance metals and parts, and understanding their innumerable applications and the customized processing parameters critical to their performance, has been at the heart of our business since its inception.
