Platinum Wire Property

Precious metal wires are widely used in industry, including resistance thermometers and flammable gas detectors.The specifications of wire can be customized according to the requirements of customers, including the resistance, temperature coefficient and tensile requirements of some ultra-fine precious metal wires.

Pure platinum wire has specialty like high melting point, oxidation resistance, stable chemical properties, etc, it is suitable for processing and manufacturing standard thermocouple platinum materials, we produce various specifications of pure platinum wire, which are widely used as industrial platinum resistance thermometer and conduction of precision instrument baseline, etc.

We can make platium wire dimension from 0.02mm-3.0mm
