Huona Hot Sale TM-1/FPA223-80/5J1480 Bimetallic Strip 0.1mm Thickness × 100mm

TM-1 bimetallic strip (0.1mm×100mm), a precision-engineered functional material from Huona New Material, is a thin-gauge composite strip composed of two dissimilar alloys with distinct thermal expansion coefficients--bonded via our proprietary hot-rolling diffusion technology. Optimized for ultra-thin applications requiring both miniaturization and reliable thermal actuation, this strip combines a fixed 0.1mm thickness (ideal for compact devices) with a 100mm standard width (suited for large-area temperature sensing or batch processing). Leveraging Huona's expertise in thin-gauge composite manufacturing, the TM-1 grade delivers exceptional thermal sensitivity, uniform deformation, and strong interfacial bonding--making it a core component for micro-thermostats, precision temperature compensators, and miniaturized overheat protection devices.

• Product Grade: TM-1 (specialized bimetallic grade, tailored for ultra-thin gauge thermal responsiveness)
• Dimensional Specification: 0.1mm thickness (tolerance: ±0.003mm) × 100mm width (tolerance: ±0.15mm)
• Composite Structure: Typically features a high-expansion layer (e.g., Cu-Mn-Zn alloy, α≈20×10⁻⁶/℃) and a low-expansion layer (e.g., Fe-Ni 36 alloy, α≈1.6×10⁻⁶/℃), with interfacial shear strength ≥145 MPa (tested per GB/T 14985)
• 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, with in-house thin-gauge rolling and precision slitting capabilities

The TM-1 strip (0.1mm×100mm) stands out for its ultra-thin design and large-width suitability:

• Ultra-Thin Precision: 0.1mm thickness (30% thinner than common 0.15mm strips) enables integration into micro-devices (e.g., wearable sensors, miniaturized circuit breakers) while maintaining strict thickness uniformity (±0.003mm) to avoid uneven thermal deformation.
• Enhanced Thermal Sensitivity: High expansion coefficient ratio (~12.5:1) delivers a temperature-induced curvature of 12-15 m⁻¹ (at 100℃ vs. 25℃)--20% higher than thick-gauge strips (0.3mm+), ensuring fast actuation in low-power devices.
• Large Width for Batch Processing: 100mm standard width matches industrial stamping panel sizes, allowing simultaneous production of 50+ micro-components (e.g., thermostat contacts) per strip--reducing processing time by 40% vs. narrow-width strips.
• Strong Interfacial Bonding: Proprietary diffusion bonding technology eliminates delamination even after 8,000 thermal cycles (-40℃ to 180℃)--solving the common issue of thin-gauge bimetallics (≤0.1mm) being prone to layer separation.
• Excellent Machinability: Ultra-thin gauge enables laser cutting into intricate micro-shapes (minimum feature size: 0.5mm) and tight bending (radius ≥1× thickness) without cracking--critical for automated assembly of compact devices.

• Micro-Thermostats: Temperature control in wearable devices (e.g., smart watches), medical insulin coolers, and miniaturized HVAC systems (0.1mm thickness fits slim designs).
• Precision Overheat Protection: Circuit breakers for lithium-ion batteries (e.g., drone batteries, wireless earbuds) and micro-motors (fast actuation prevents thermal runaway).
• Large-Area Sensing: Thermal profiling strips for PCB boards (100mm width covers multiple components) and flexible electronics (uniform temperature response across the strip).
• Consumer Electronics: Thermal actuators for laptop heat sinks, printer fuser controls, and smartphone battery protection modules.
• Industrial Micro-Devices: Temperature-compensating shims for MEMS sensors (e.g., pressure sensors in autonomous vehicles) and tiny thermal switches for IoT devices.

Huona New Material subjects every batch of TM-1 strips (0.1mm×100mm) to rigorous testing: interfacial shear strength verification, 1000-cycle thermal stability tests, and laser-based dimensional inspection. Free samples (100mm×50mm) and thermal curvature vs. temperature curves are available upon request. Our technical team provides tailored support--including alloy layer optimization for specific actuation temperatures and micro-stamping process guidelines--to ensure the strip meets the demands of compact, high-precision applications.
