Product Description
5J1480 Thermostatic Bimetallic Strip (Huona)
5J1480 thermostatic bimetallic strip from Huona New Material is a precision composite material formed by metallurgically bonding two metal layers with distinct thermal expansion coefficients. It produces predictable, reversible bending deformation in response to temperature changes, making it ideal for sensitive thermal actuation, precise temperature control, and low-temperature overheat protection devices.
