Product Description
Huona Bimetal Strip Telcon 140/5J1480/TM-1 (0.20×14mm)
Product Overview

The Telcon 140/5J1480/TM-1 bimetal strip is a high-precision thermal response material featuring a specialized two-layer composite structure with fixed specifications of 0.20mm (thickness) ×14mm (width). Composed of a high-expansion active layer (Ni22Cr3 alloy) and a low-expansion passive layer (Ni36 invar alloy), it delivers:

  • Sensitive temperature-induced bending deformation
  • Stable mechanical properties
  • Wide temperature adaptation range (-70℃ to 350℃)

With its bright surface finish and excellent dimensional accuracy, this strip is widely used in automatic control devices and instrumentation for temperature control, compensation, and indication functions.

Standard Designations & Core Structure
  • Product Model: "Telcon 140" (equivalent to Kanthal 135, FPA 223-80); "5J1480" (Chinese standard); "TM-1" (ASTM TM1 compliant)
  • Specifications: 0.20mm ×14mm (thickness tolerance ±0.005mm, width tolerance ±0.1mm)
  • Equivalent Grades: Kanthal 135, Neomax BL-5, Imphy R80; complies with ASTM TM1 and GB/T 4461-2004
  • Manufacturing Process: Vacuum smelting → hot rolling → multi-pass cold rolling → precision annealing → surface polishing
Key Advantages
1. Sensitive Thermal Response & Stable Deformation
  • Bending coefficient K of 14.3×10⁻⁶/℃ (20-135℃) and temperature bending rate F of 26.2%±5%
  • 100mm-long strip bends ≥1.4mm when heated from 20℃ to 120℃
  • Temperature range: -70℃ to 350℃ with ≤3% bending coefficient decay after 1000 hours at 300℃
2. Excellent Mechanical Properties
  • Interfacial shear strength ≥150MPa with no delamination after 500 thermal shock cycles
  • Vickers hardness HV 180-220 and elongation ≥8% at 25℃
  • Can be bent 180° around 1mm mandrel without cracking
3. High Dimensional Accuracy
  • Thickness tolerance ±0.005mm, width tolerance ±0.1mm, flatness ≤0.1mm/m
  • Surface roughness Ra ≤0.2μm for excellent process compatibility
  • Electrical resistivity 0.8±5% Ω*mm²/m at 20℃
