Molecular formula : MW : CAS :
nature : solid expansion (type) of a sensitive thermometer components. From two different linear expansion coefficient of metal welded together closely. Brass is used (when the switch to the use of high-temperature nickel alloy) and steel. When heated, as the linear expansion so different sheet metal deflection occurred. For signaling equipment, automatic control system or other equipment such as body temperature compensation. Temperatures bimetal undergoing tremendous stress, even more than its elastic limit. So seldom used at a temperature of 200 ° C above occasions.
