What is a High Purity Foil?

A high purity foil is a thin sheet of metal that has been processed to contain a minimal amount of impurities—often with a purity level of 99.9% or higher. These foils are produced using advanced refining techniques to remove unwanted elements and contaminants, ensuring that the material's properties, such as electrical conductivity, thermal conductivity, and chemical stability, are maximised. High purity foils are characterised by their ultra-thinness, ranging from micro-metre to sub-micro-metre thicknesses, making them incredibly versatile for specialised applications. The purity level of these foils plays a crucial role in enhancing their performance, especially in applications where even trace impurities can cause failures or inconsistencies.
