non-ferrous metal metallurgy

Non-ferrous metals refer to all metals except ferrous metals composed of iron, manganese and omium. It is an indispensable material for the development of modern industry, modern national defense and modern science and technology. With the enhancement of national environmental protection awareness, the control of non-ferrous metal smelting, processing and casting dust has attracted great attention. Generally non-ferrous metal smelting uses PTFE needle felt filter material or PPS needle felt filter material, because they have good corrosion resistance and high temperature resistance.
