HIP cylinders.

During hot isostatic pressing (HIP), materials are sintered, combined and compacted at temperatures of approximately 1 450 °C (2642°F) and gas pressures of up to 200 MPa. System components inside the pressure vessel not only have to be large; they must also be heat-resistant and be able to withstand rapid changes of temperature. That sounds like a job for our metals. We produce our HIP cylinders, support structures and heating assemblies from molybdenum, ML or TZM and supply additional gas supply and rapid cooling components.

When other materials give up, it's time for molybdenum and tungsten to take over. These two materials are both refractory metals and are ideally suited for use at high temperatures. With their special properties, molybdenum and tungsten are the perfect choice for components in the furnace construction industry.

  • High melting points permitting operating temperatures of up to 2 800 °C (5 072 °F)
  • Outstanding creep resistance
  • High level of dimensional stability
  • Excellent corrosion resistance
  • Low coefficient of expansion

Whenever materials have to meet special challenges, we add titanium and zirconium to strengthen the microstructure of pure molybdenum. Mo-Ti solid solution and Ti-Zr carbides ensure that optimum strengths are achieved at temperatures up to 1 400 °C (2552 °F).


What can TZM do better than pure molybdenum?

  • Better creep resistance
  • Higher recrystallization temperature
  • Greater thermal stability

We're here.

It makes no difference whether you need an entire hot zone or simply a spare part for your existing furnace. With Plansee, you are in good hands. We are happy to install your products for you at your premises. And, of course, we are there to lend a hand when it comes to inspecting, maintaining and optimizing existing furnaces.

A single source for all your needs.

We handle every stage in the manufacture of our products in-house. From the raw materials through to the finished product: including the development of new materials. In this way, we can guarantee that you benefit from the very best quality.

We compress our metal powders and powder mixes at pressures of up to 2 t/cm² (tonnes per square centimetre) to form a so-called green compact. When end products with particularly demanding geometries are required, we make sure as ear
