Description

Technical Field

[0002] Titanium alloy and zirconium alloy are one of the main corrosion-resistant materials, both of which have strong corrosion resistance and have their own advantages for different corrosive media. Relatively speaking, for most corrosive media, the corrosion resistance of zirconium alloy is stronger than that of titanium alloy, and the corrosion resistance of hafnium alloy is equivalent to that of zirconium alloy, but it is less used due to its high price. Titanium, zirconium and hafnium are rare metals of the same family. Titanium has excellent properties such as low density, high strength and strong corrosion resistance, and is an important alloying element. Zirconium has excellent properties such as high melting point, high strength and strong corrosion resistance. Hafnium has excellent properties such as high density, high melting point and strong corrosion resistance.
