Product Overview
The TB200/10 bimetallic strip is a composite material formed by bonding two metal layers with distinct thermal expansion coefficients: a high-expansion layer (Cu-Zn alloy) and a low-expansion layer (Fe-Ni alloy). The "200" denotes its maximum continuous operating temperature (200°C), while "10" refers to its thermal deflection coefficient (10×10⁻⁶/°C in the 20-100°C range). This strip delivers stable, repeatable bending behavior under temperature changes, making it suitable for medium-precision thermal control devices and safety switches.
Standard Designations
- Industry Classification: Conforms to DIN 17155 for bimetallic strip performance
- Material Code: TB200/10 (temperature class/deflection coefficient)
- Equivalent Grades: Similar to Type B in GB/T 4461 and Class 3 in ASTM F2144
Key Features
- Controlled Deflection: 1.0mm bending per 100mm length at 100°C (20°C reference)
- Temperature Stability: Continuous operation at -40°C to 200°C; short-term up to 220°C
- Mechanical Durability: Withstands ≥10,000 thermal cycles without fatigue failure
- Cost-Effective: Balances performance and affordability for general industrial use
- Formability: Easy to cut, bend, and stamp into custom shapes for diverse applications
