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. For thin film coating application, it is used to manufacture catalytic converters, semiconductors, fuel cells, optics and batteries. 

The dimensions and purities can be customized upon request. Please contact us for customization or bulk orders.
