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.
Manufacturer: Huona New Material (Shanghai) Co., Ltd., certified to ISO 9001 and IATF 16949
Key Core Advantages
Sensitive & Stable Thermostatic Response
Moderate Curvature Sensitivity: Curvature temperature coefficient of ~8.0×10⁻⁶ /℃, ideal for applications requiring balanced sensitivity and mechanical strength
Reversible Deformation: Fully reversible thermal cycling without permanent deformation or fatigue, ensuring long-term reliability
Excellent Mechanical Properties
High Strength & Formability: Tensile strength ≥520MPa, elongation ≥18%, enabling complex stamping, bending, and punching operations
Good Fatigue Resistance: Withstands repeated thermal cycling without cracking or performance degradation, suitable for dynamic applications
Uniform Quality & Consistency
Precision Rolling: Tight thickness and width tolerances ensure uniform thermal response across the entire strip
Strong Interlayer Bonding: Metallurgical bonding between high- and low-expansion layers prevents delamination under thermal and mechanical stress
Versatile Processability
Easy Forming: Compatible with stamping, bending, punching, and riveting to produce complex bimetallic elements
Weldability: Suitable for resistance welding and soldering, enabling seamless integration into electrical and mechanical components
Reliable Environmental Resistance
Corrosion Resistance: Good resistance to atmospheric corrosion and mild chemicals, suitable for industrial and consumer applications
Wide Temperature Stability: Maintains consistent thermostatic performance across -70℃ to 200℃, suitable for low-temperature environments
