PC70 Carbon/Carbon Springs

Our Carbon/Carbon springs are designed to be used where your application needs a constant force applied in high-temperature vacuum environments. 

The springs offer excellent durability with and consistently work over a wide range of temperatures without loss of performance. 
 
Performance C/C Springs

The Carbon/Carbon spring is an excellent option for brazing applications. The springs are used to replace "deadweights" that are typically used in Brazing fixtures. Our C/C springs offer very precise and equal forces during heat-treatment brazing. This cannot be achieved in the same using a "deadweight" on a brazing fixture. Not only do you have a precise force using the C/C Spring you reduce the weight of your brazing fixture while having higher quality brazing results. 

C/C springs are considerably lighter, this allows users to have a smaller brazing fixture due to not needing to support the same weight as a traditional brazing fixture using deadweights. This allows users to increase their productivity by using more smaller higher performing fixtures due to the smaller fixture size and weight savings. 

Faster Production Cycles

C/C Springs do not require less thermal energy levels compared to deadweights to reach optimal brazing temperatures. 

Energy Efficiency 

C/C springs are more energy efficient due to excellent thermal conductivity. This makes a brazing fixture with a C/C spring more energy efficient. This helps reduce energy consumption which helps low overall production costs.
