Zirconium plates, zirconium sheets
Zirconium and zirconium alloys have a series of characteristics such as low density, high specific strength, corrosion resistance, radiation resistance, excellent wear resistance, excellent processing performance, non-toxic, non-magnetic, and small thermal neutron absorption cross-section.
In view of the fact that zirconium and zirconium alloys have the characteristics of low density, high specific strength, corrosion resistance, radiation resistance, excellent wear resistance, excellent processing performance, non-toxic, non-magnetic, etc., they are different from traditional stainless steel, copper, nickel, titanium and other metal alloys. , zirconium and zirconium alloys have excellent corrosion resistance and can withstand corrosion from most organic acids, inorganic acids, strong alkali and some molten salts. In the wastewater treatment, food processing, and strong acid production industries, it is mainly used in equipment and components with high corrosion resistance requirements, such as reactors, acid-resistant pumps, heat pumps, heat exchange pipes, soaking tanks, acid-resistant impellers, valves, etc., agitators, Spout and container lining.
