Platinum Wire Applications

Thermocouples & Temperature Sensing

Our platinum and platinum-rhodium wire is manufactured to support Type R (Pt/Pt-13%Rh) and Type S (Pt/Pt-10%Rh) thermocouple configurations, used for accurate, repeatable high-temperature measurement in furnaces, kilns, and industrial process monitoring.

Electrodes & Electrochemistry

Platinum’s chemical inertness and stable electrochemical behaviour make our wire a reliable choice for reference and working electrodes, analytical instruments, and electrochemical research.

Medical & Scientific Instrumentation

Platinum wire’s biocompatibility and corrosion resistance support its use in implantable devices, precision sensors, and specialist scientific instruments.

Industrial & High-Temperature Processing

From furnace components to catalytic and aerospace applications, our platinum wire performs reliably in environments where oxidation resistance and dimensional stability are critical.

Platinum wire is used in thermocouples, electrochemical electrodes, medical devices, and high-temperature industrial processes, thanks to its purity, corrosion resistance, and thermal stability.

Birmingham Metal supplies platinum wire from 0.1mm to 1.5mm in diameter, with custom sizes available on request.

Type R uses a Pt/Pt-13%Rh pairing and Type S uses Pt/Pt-10%Rh — both use a pure platinum negative leg, which Birmingham Metal supplies to the correct specification for each type.

Yes — used platinum wire retains most of its value. Birmingham Metal’s recycling service refines returned wire and credits the value towards new orders.
