Synthetic graphite is used as engineered material to create precision machined plates, posts, nuts and bolts along with heating elements and fixtures used in the heat treatment of aerospace metals such as (titanium, stainless steel, and other alloys). The heat treatment process is used to give these metals improved strength, flexibility, or hardness.
Generally the graphite plates are preferred as fixtures because they are inert and do not transfer any chemistry or metals to the aerospace metal being treated.
In addition, graphite plates are long lasting and can be reused numerous times providing a cost effective solution to heat treating of exotic materials.
As an extension of heat treating for aerospace, a common graphite use is as a susceptor. “A susceptor is a material used for its ability to absorb electromagnetic energy and convert it to heat.”
Now this really explores the use of graphite as graphite susceptors are not only used for aerospace metals, but also for non-metal composites, and increasingly used for aerospace electronics (semiconductors) production.
Another use for graphite is as a mold. Graphite molds are used to cast titanium, aluminum, and stainless steel to near net shapes.
Graphite itself is used for jet and rocket engine nozzles and Carbon/Graphite vanes, impellers and rotors move aviation fuel safely without the dangers of creating sparks to ignite fuel.
The aerospace industry requires severe safety demands with components that are both reliable and resistant to extreme environments. XRD graphite's solutions have served the civil, commercial, and military sector for many years. We work closely with our customers to develop customised solutions that provide outstanding performance in the most demanding of applications.
Our graphite products also are recognised as the industry standard in the China for military applications, as they offer outstanding performance within a range of vital properties including:
- High purity and dimensional stability
- Outstanding resistance to pocketing
- Consistent performance in extreme temperature environments
