MSE PRO 3N5 (99.95%) Platinum (Pt) Wire Evaporation Materials
To better serve you, we would like to discuss your specific requirement, Please Contact Us for a quote.
Platinum (Pt) is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. It is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry. Due to its high value, it is usually a coating material in catalytic converter, manufacture of semiconductors, fuel cells, optics and batteries.
Our standard size is 0.5mm Diameter x 1m Length.
The dimensions and purities can be customized upon request. Please contact us for customization or bulk orders.
