1. What’s Zirconium.

Zirconium is a reactive metal that has a high affinity for oxygen resulting in

the formation of a protective oxide layer in air at room temperature.

It also is a special metal alloys. With high price like titanium alloys,

especially more expensive than titanium alloys.

It with excellent corrosion resistance and widely used in chemical process.

Like heat exchangers.

It’s density is 6.49, bigger than 4.51 for titanium.

Zirconium alloys exhibit good ductility even at cryogenic temperatures and

good strength comparable with other common engineering alloys.

4. Application for Zirconium seamless tubes

Zirconium 702 tubing is resistant in most organic acids and mineral

acids. Typical applications for seamless zirconium tubing are as heat

exchangers, coolers, condensers and piping systems in the production

of urea, acetic acid, formic acid, nitric acid and methyl methacrylate.
