Product Description
0.16mm x 27mm P675R/TM2/TB20110 Bimetallic Strip ASTM B388 Rapid Thermal Response & Durability
Product Overview
The P675R bimetallic strip (0.16mm×27mm), a precision-engineered functional material from Huona New Material, is a specialized composite strip composed of two dissimilar alloys with distinct thermal expansion coefficients--firmly bonded via our proprietary hot-rolling and diffusion bonding technology. With a fixed thin gauge of 0.16mm and standard width of 27mm, this strip is optimized for miniaturized temperature-sensitive applications, where precise thermal actuation, stable dimensionality, and space-saving design are critical.
Standard Designations & Core Composition
- Product Grade: P675R
- Dimensional Specification: 0.16mm thickness (tolerance: ±0.005mm) × 27mm width (tolerance: ±0.1mm)
- Composite Structure: Typically features a "high-expansion layer" and a "low-expansion layer", with interfacial shear strength ≥160 MPa
- Compliant Standards: Adheres to GB/T 14985-2017 (Chinese standard for bimetallic strips) and IEC 60694 for thermal control components
- Manufacturer: Huona New Material, certified to ISO 9001 and ISO 14001
Key Advantages
- Ultra-Thin Stability: Maintains uniform thickness (0.16mm) and no interfacial delamination--even after 5000 thermal cycles (-40℃ to 180℃)
- Precise Thermal Actuation: Controlled 温曲率 (temperature-induced curvature) of 9-11 m⁻¹ (at 100℃ vs. 25℃), with actuation temperature deviation ≤±1.5℃
- Fixed Width for Automated Production: 27mm standard width matches common micro-stamping die sizes, reducing material waste by ≥15%
- Good Machinability: Thin 0.16mm gauge enables easy bending (minimum bending radius ≥2× thickness) and laser cutting
- Corrosion Resistance: Optional surface passivation treatment provides 72-hour salt spray resistance (ASTM B117)

Typical Applications
- Compact Temperature Controls: Micro-thermostats for wearable devices, small household appliances, and medical devices
- Overheat Protection: Miniature circuit breakers for lithium-ion batteries and micro-motors
- Precision Compensation: Temperature-compensating shims for MEMS sensors
- Consumer Electronics: Thermal actuators for laptop keyboard backlight controls and printer fuser temperature regulators
- Industrial Micro-Devices: Tiny thermal switches for IoT sensors and automotive micro-components
Huona New Material subjects every batch of P675R bimetallic strips (0.16mm×27mm) to rigorous quality testing. Free samples (50mm×27mm) and detailed performance reports are available upon request.
