BIMETALLELEMENT UND VERFAHREN ZU SEINER HERSTELLUNG

摘要

A bimetal is disclosed having a high, rapid deflection over a specified temperature range, including a high expansion metal alloy component having a high thermal expansion coefficient that changes rapidy at 50x10-6/ DEG C. or greater at a temperature of between about 100 DEG C. and 250 DEG C. and containing from 15-30% by weight of manganeses, the balance of iron. The second component has a substantially constant thermal expansion coefficient regardless of the temperature change, and is preferably a stainless steel. These bimetals are used in circuit breakers, thermal protectors and the like.
