Video of the 10th powerful Advantage “CFC-Fixtures help to reduce hard machining” by High Temperature Concept

Joerg Demmel • July 22, 2025

Today I, Dr. Jorg Demmel, like to introduce the Advantage Number 𝟭𝟬 of CFC Fixtures in a video world premiere. In total there are 10 Advantages I like to share with you.

 

“𝗖𝗙𝗖-𝗙𝗶𝘅𝘁𝘂𝗿𝗲𝘀 𝗵𝗲𝗹𝗽 𝘁𝗼 𝗿𝗲𝗱𝘂𝗰𝗲 𝗵𝗮𝗿𝗱 𝗺𝗮𝗰𝗵𝗶𝗻𝗶𝗻𝗴.𝗚𝗿𝗲𝗮𝘁 𝘀𝗮𝘃𝗶𝗻𝗴𝘀 𝗶𝗻 𝘁𝗶𝗺𝗲, 𝗺𝗼𝗻𝗲𝘆 𝗮𝗻𝗱 𝗾𝘂𝗮𝗹𝗶𝘁𝘆 𝗮𝗿𝗲 𝗽𝗼𝘀𝘀𝗶𝗯𝗹𝗲 𝗰𝗼𝗺𝗽𝗮𝗿𝗲𝗱 𝘁𝗼 𝘀𝘁𝗲𝗲𝗹 𝗳𝗶𝘅𝘁𝘂𝗿𝗲𝘀.”


Please see for yourself by watching the video, which provides unique insights in the world of CFC-Fixtures and Racks and handling automation.


CFC is a unique material with properties never reached.

 

The Coefficient of thermal expansion, short C.T.E. value, is around zero. CFC doesn’t change dimensions and form in technical vacuum or inert gas atmospheres. 

 

Even extreme thermal shocks don't change or weak Carbon Fiber Reinforced Carbon (CFC). If you are using technical oil quenching media or High Pressure Cooling technology, CFC Fixtures are the best choice.

 

Furthermore, CFC is not creeping at high temperatures under load and not aging caused e.g. by carburizing furnace atmospheres. Vacuum and inert gases are CFCs’ best friends.

 

Additionally, CFC increases its strength to higher temperatures to a maximum at around 2,200  oC or 3,992  oF. Do you know any other material with this quality?

 

Therefore, the products stay accurate at the same place in their CFC-Rack or Fixture.

At High Temperature Concept, we’re excited about how CFC-Fixtures can revolutionize heat treatment operations across industries. If you’re looking to save energy, improve product quality, and reduce cycle times, exploring CFC technology could be the next big step for your shop.
