Product Description
Thermostatic Bimetallic Strip – Grade 5J1580 (0.25mm × 15mm Multi-Coil Pack)
Product Overview
This multi-coil pack of 5J1580 thermostatic bimetallic strip (0.25mm thickness × 15mm width) is a high-performance, mid-sensitivity thermal composite material designed for medium-load industrial and consumer temperature control applications. It is manufactured by vacuum metallurgical bonding of a manganese-nickel-chromium high-expansion layer and a controlled low-expansion nickel-iron alloy, followed by precision rolling and multi-stage stress-relief annealing. The material delivers balanced thermal response, excellent mechanical strength, and stable fatigue resistance, making it ideal for high-cycle thermal switches, safety cutouts, and precision compensation elements.

Key Differentiating Advantages
1. Balanced Thermal Sensitivity for High-Cycle Use
With a specific bending coefficient of ~220×10⁻⁶/℃, this grade strikes an optimal balance between thermal response and mechanical robustness. It provides reliable, repeatable bending displacement even after tens of thousands of thermal cycles, making it ideal for continuous-duty thermal switches and motor protectors.
2. Enhanced Mechanical Strength & Formability
The material exhibits a tensile strength ≥530MPa and elongation ≥17%, enabling complex stamping, deep bending, and precision punching into multi-functional thermal elements. Its uniform grain structure minimizes cracking during forming, supporting high-volume production of intricate components.
3. Optimized Electrical Resistivity for Hybrid Applications
With a resistivity of 0.82 μΩ·m, 5J1580 is engineered for use in both temperature-sensing and self-heating thermal control devices. It supports moderate self-heating currents without excessive voltage drop, simplifying the design of integrated thermal safety components.
4. Multi-Coil Pack for Industrial Scale Production
This multi-coil configuration (6 coils per pack) is tailored for large-scale manufacturing operations, ensuring consistent material properties across production runs. Each coil is individually marked and packaged to prevent cross-contamination, streamlining inventory management and traceability.
5. Superior Thermal Fatigue & Environmental Stability
The material maintains stable performance across its full temperature range, with no permanent deformation or delamination after repeated thermal cycling. It also offers good resistance to atmospheric corrosion and mild industrial chemicals, making it suitable for use in HVAC systems, automotive electronics, and general industrial environments.
