Product Overview
The P675R bimetallic strip is a high-performance composite material composed of two layers of metals with distinct coefficients of thermal expansion. The high-expansion layer is made of Mn75Ni15Cu10, while the low-expansion layer is Ni36. This combination enables predictable bending or deformation in response to temperature changes.
Standard Designations
- Material Standards: Conforms to DIN 17155 and ASTM B388
- Industry Codes: Class A thermosensitive material under IEC 60730-2-9
- Alternative Designations: Equivalent to Thermalloy 675 and Bimet 75-36
Key Features
- High Deflection Sensitivity: 0.25mm deflection per 10°C at 100mm length (20-100°C range)
- Low Hysteresis: <2°C deviation between heating and cooling response
- Long-Term Stability: <1% deflection loss after 10,000 thermal cycles (-40 to 150°C)
- Electrical Conductivity: 8.5 S/m (enables use in current-carrying thermal switches)
- Corrosion Resistance: Passes 500-hour salt spray test (ASTM B117)
