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

Technical Specifications

Attribute Value
Total Thickness Range 0.1mm - 2.5mm (tolerance: ±0.01mm)
Width Options 3mm - 120mm (tolerance: ±0.05mm)
Layer Thickness Ratio (High:Low) 1:1 (custom ratios 2:1, 3:1 available)
Operating Temperature Range -50°C to 180°C (continuous)
Maximum Short-Term Temperature 200°C (≤10 minutes)
Tensile Strength 480MPa (transverse direction)
Elastic Limit 220MPa
Thermal Deflection Coefficient 21.2 × 10⁻⁶ /°C (20-150°C)

Material Composition

Layer Main Elements (wt%) Trace Elements (max, wt%)
High-Expansion (Mn75Ni15Cu10) Mn:75, Ni:15, Cu:10 C:0.03, Si:0.2, Fe:0.5
Low-Expansion (Ni36) Ni:36, Fe:64 C:0.02, Mn:0.3, Si:0.1

Product Specifications

Item Detail
Surface Finish Annealed (Ra ≤0.8μm) or bright rolled (Ra ≤0.4μm)
Cutting Options Slit strips, cut-to-length pieces, or continuous rolls
Length per Roll 50m, 100m, 300m (on 300mm diameter plastic spools)
Adhesion Strength ≥150MPa (layer bond strength, ASTM D3163)
Packaging Vacuum-sealed in moisture barrier bags with desiccants

Typical Applications

  • Domestic appliance thermostats (ovens, water heaters, dryers)
  • Overcurrent protection devices (motor overload relays)
  • Fire safety sensors (heat detectors)
  • Automotive underhood temperature switches
  • Industrial process temperature regulators


We provide custom slitting, forming, and heat treatment services for P675R strips. Free samples (100mm × 20mm) and thermal deflection test reports are available upon request.
