In view of the fact that zirconium and zirconium alloys have low density, high specific strength, corrosion resistance, radiation resistance, excellent wear resistance, excellent processing performance, non-toxic, non-magnetic, compared with traditional stainless steel, cobre, níquel, titanium and other metal alloys, zirconium and zirconium alloys have excellent corrosion resistance, which can resist the corrosion of most organic acids, inorganic acids, strong bases and some molten salts. In wastewater treatment, processamento de alimentos, strong acid production industry, it is mainly used in equipment and components with high requirements for corrosion resistance, such as reactor, acid resistant pump, heat pump, heat exchange pipe, immersion tank, acid resistant impeller, valve, agitator, nozzle and container lining. The zirconium equipment and devices used by American chemical enterprises have been in use for more than 25 years without obvious corrosion damage. The conversion rate is as high as 85% ~ 90%, which greatly improves the production efficiency of enterprises. In the process of deep-sea exploration, zirconium alloy can not only withstand the erosion of sea water and sand, seawater corrosion and fluid friction and wear, but also adapt to the alternating temperature environment of - 200 ~ 200 °C. This is due to the low thermal expansion coefficient of zirconium, which can be stably and continuously used. The absorption cross section is small
