The use of screw drives in the field of high-energy radiation is made possible by the use of special materials.

Depending on which radiation is present (electromagnetic radiation, radioactive radiation, electron radiation, neutron radiation, ion radiation) and how high the dose and the duration of the radiation exposure is, different materials can be used.

In the case of metallic materials, Cr-Ni steels with 15-17% Cr and 13-16% Ni are mainly used, and aluminum alloys are also used occasionally.

For thermoplastic materials, PVDF, PI, PEI, PSU and PEEK in particular have proven their worth. With these materials, radiation resistances of up to 1×10 ⁵ Gy reached.

If the radiation intensity is low, the inexpensive material ABS can also be used.

junaspin is happy to support you in the selection and design of your screw drive, also with regard to high-energy radiation.
