Zirconium is a chemical element with the symbol Zr and atomic number 40. The name zirconium is taken from the name of the mineral zircon (the word is related to Persian zargun (zircon; zar-gun, "gold-like" or "as gold"), the most important source of zirconium. It is a lustrous, grey-white, strong transition metal that closely resembles hafnium and, to a lesser extent, titanium.

Grinding characteristics of zirconium alloys Firmetal, 09:08:00 PM. 1, large chemical activity, easy oxidation. Zirconium alloy is easy to form an oxide layer in the air, and the strength and hardness of the oxide surface layer are higher, so the grinding force per unit area is larger. 2. Zirconium alloy is very viscous, and it is easy to jam the grinding wheel when grinding.
