Description

Product Description

P675R Bimetallic Strip

Product Overview

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 typically made of Mn 75 Ni 15 Cu 10, while the low - expansion layer is Ni 36. This unique combination enables the strip to bend or deform predictably in response to temperature changes, making it a fundamental component in a wide range of temperature - sensitive applications.

Standard Designations

  • Material Standards: Conforms to DIN 17155 and ASTM B388 for bimetallic strip performance
  • Industry Codes: Recognized as a Class A thermosensitive material under IEC 60730-2-9
  • Alternative Designations: Equivalent to grades such as 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) with minimal oxidation
