RL5J20110 Thermostatic Bimetallic Strip

Product Overview

RL5J20110 thermostatic bimetallic strip is a high-sensitivity, high-resistivity precision composite material developed for demanding thermal actuation and control applications. It is manufactured by vacuum diffusion bonding of a high-expansion manganese-nickel-copper alloy layer and a low-expansion nickel-iron alloy layer, followed by precision cold rolling and stress-relief annealing. This material delivers rapid thermal response, stable electrical resistivity, and excellent mechanical durability, making it ideal for applications requiring precise and reliable temperature-driven motion.

Key Core Advantages

1. Ultra-High Thermal Sensitivity

RL5J20110 exhibits exceptional thermal response, with a specific bending coefficient ≥290×10⁻⁶/℃. This allows for large, measurable bending displacement in response to small temperature changes, enabling the design of compact, highly responsive thermal switches and control elements.

2. Integrated High Electrical Resistivity

With a stable resistivity of 1.13 μΩ·m, this grade eliminates the need for separate resistive components in self-heating thermal switches and overload protectors. It combines temperature sensing and heating functions in a single element, simplifying circuit design and reducing component count.

3. Superior Structural Integrity

The vacuum diffusion bonding process ensures metallurgical fusion between the high and low expansion layers, resulting in exceptional interlayer bonding strength (≥150MPa). This prevents delamination even after thousands of thermal cycles, ensuring long-term reliability in dynamic applications.

4. Precision Formability & Consistency

Tight dimensional tolerances and a uniform microstructure enable precise stamping, bending, and punching into complex geometries. The material maintains consistent performance across the entire coil, ensuring batch-to-batch uniformity for high-volume production.

5. Excellent Environmental Stability

RL5J20110 offers good resistance to atmospheric corrosion and thermal fatigue. It performs reliably in both indoor and mildly corrosive industrial environments, making it suitable for use in home appliances, automotive systems, and industrial controls.
