ZEDEX® 750 family

Cryogenics, high temp & high PV – up to 280°C
ZX-750® family is suitable for very high temperatures, combined with high pv values. However, thanks to its low brittle point it can also be used in cryogenic applications.

ZX-750V5T® should always be used when the operating temperature exceeds 200°C and the loads, service life and dimensional stability have to be improved. ZX-750V5T® has the highest permissible surface pressure for speeds between 10 and 200 m/min and the best wear values at 150°C among the ZEDEX® materials.

The modification ZX-750V5KF® has almost the same aluminium CTE and its resilience values at -196°C are the 2nd best after ZX-324V11T® among the ZEDEX® materials.

When to use the family ZX-750® ?

  • At very high temperatures
  • At very low temperatures
  • At very high pv values

When is the ZX-750® not suitable?

  • If low water absorption is required (e.g. the family ZX-530®)
  • If FDA conformity is required (e.g. the family ZX-530®)
  • For cost-effective applications or undemanding components (many materials for this)

What can be replaced?
