Yesterday, all the Chinatungsten’s interns took tests for examing the mastery of professional knowledge about tungsten, molybdenum as well as their related products. The participants wrote several good passages about our products, and here I wanna share them with all of you.

The following passage, written by Miss Yu, was about TZM, a really good brief introduction about TZM for you:

As we all known that TZM (titanium zirconium molybdenum) alloy is an alloy of which contents 0.4~0.5%Ti, 0.06~0.12%Zr and 0.01~0.04% Carbon with balanced molybdenum.

TZM  alloy has a higher recrystallization temperature, good strength, hardness and better ductility at room and elevated temperatures than unalloyed Molybdenum. In addition, TZM exhibits good thermal conductivity, low vapor pressure, good corrosion resistance and is easy machined than pure molybdenum.

TZM alloy is used for jet tube of flying vehicle and a variety of components of high inlet temperature, high pressure turbine engine, such as hot gas seals and valves, turbine wheels or wheel blades.

The method of TZM alloy process is powder metallurgy. Firstly, mixing proportionally high-purity molybdenum powder with THi2 powder, ZrH2 powder and carbon together in the furnance, then pressed by cold isostatic and sintered at high temperature H2/N2 protective atmosphere to get a TZM blank.

Secondly, taking the TZM blank into the following steps: rolled at high temperatures, forged under high annealing temperature, annealed in medium temperature to eliminate stress then rolled in lower temperature to obtain TZM finished material.

Lastly, we can give users many options in selecting a material to satisfy their specific application requirements by established processes. It is can processed into forging billets, bar, rod, sheet, plate and foil.

It is reported that the prices of TZM dropped in this week. If you are interester in our TZM products, you can send email to us for more information and the email address is sales@chinatungsten.com  or biz@ctia.com.cn.
