Zirconium sheet
Zirconium (Zr) is not much in the earth's crust and is a rare element. At room temperature, zirconium has good corrosion resistance and toughness in acids, alkalis and various media, but the mechanical properties and corrosion resistance of zirconium and zirconium alloys decrease with the increase of temperature, and they will deteriorate when the temperature is above 500 °C. Loss of corrosion resistance, mechanical properties will also be reduced. Therefore, the weldment of zirconium and its alloys can only be used in the environment below 500 ℃.
Zirconium and its alloys have outstanding nuclear properties and excellent corrosion resistance and mechanical properties, and are widely used in the defense industry, special equipment manufacturing and other industries. However, due to the difficulty in melting and processing of zirconium alloys, the production cost is high, which greatly limits Application of zirconium material.
