R-type thermocouple wire (Class 1, 0.45mm diameter) from Huona New Material is a high-precision noble metal temperature-sensing element composed of Pt13Rh (positive electrode, 13% rhodium-87% platinum alloy) and 99.99% pure platinum (negative electrode). Crafted via vacuum smelting, multi-pass precision drawing, and high-temperature annealing processes, this 0.45mm-diameter Class 1 wire maintains stable thermoelectric potential performance across 0-1300℃ (continuous) / 0-1600℃ (short-term). It integrates ultra-high measurement accuracy, excellent high-temperature oxidation resistance, and good mechanical ductility--making it the core material for high-precision temperature measurement in laboratories, aerospace, and high-temperature industrial processes (e.g., superalloy heat treatment, semiconductor manufacturing).
Standard Designations & Core Material Foundation
Thermocouple Type: R-type (Pt13Rh/Pt; single platinum-rhodium thermocouple, compliant with IEC 60584-2 Class 1)
Manufacturer: Huona New Material, certified to ISO 9001 and IATF 16949, with specialized noble metal wire drawing lines (minimum diameter 0.05mm)
Key Core Advantages
1. Ultra-High Measurement Precision (Class 1)
Top-Tier Accuracy: Meets Class 1 requirements (±1℃ at 0-1100℃; ±[1+0.003×(t-1100)]℃ at 1100-1600℃)--far exceeding industrial-grade thermocouples. This ensures traceable, reliable data for laboratory calibration equipment and aerospace component testing.
Stable Thermoelectric Potential: After 1000 hours of continuous operation at 1200℃, thermoelectric potential drift is <2μV (equivalent to temperature error <0.2℃)--superior to S-type thermocouples in long-term high-temperature stability.
2. Optimized 0.45mm Diameter Performance
Balanced Sensitivity & Strength: The 0.45mm diameter (thinner than standard 0.5mm R-type wire) reduces thermal response time (τ₅₀ ≤2s in air at 800℃) while maintaining tensile strength ≥350 MPa (annealed state)--resisting deformation in high-temperature, high-vibration environments (e.g., aircraft engines).
Wide Temperature Range: Continuous operating temperature 0-1300℃; short-term (≤30min) up to 1600℃. The Pt13Rh/Pt alloy system forms a dense PtO₂ protective film, ensuring stable performance in high-temperature oxidizing/inert atmospheres (e.g., industrial furnace flue gas).
Mechanical Ductility: Elongation ≥18% (annealed state) enables bending to a minimum radius of 0.9mm (2× diameter) without cracking--adapting to complex sensor packaging (e.g., coiled thermocouple probes).

Conductor Material
Positive (RP): Pt87Rh13; Negative (RN): 99.99% pure Pt
Laboratory Calibration: Used as the core element of standard R-type thermocouples (for calibrating industrial high-temperature thermometers) -- Class 1 accuracy ensures data traceability to international standards.
Aerospace Component Testing: Temperature monitoring of aircraft engine turbine blades (1200-1300℃) -- fast thermal response captures transient temperature changes during engine operation.
Semiconductor Manufacturing: Temperature sensing in wafer epitaxy equipment (800-1000℃) -- stable thermoelectric potential avoids process errors caused by temperature fluctuations.
