Experts in bespoke graphite machining and advice

Our senior management team have been in the graphite industry since the late 1970s, so we’ve built up a vast range of experience and an unrivalled level of knowledge across many fields or industries.

We are still seeing new applications and uses for graphite, and we often cross-fertilise ideas from one industry to another, delivering cost savings to our customers.

Anyone can sell something cheaper but at the end of the day, with no change in design, over time, either quality suffers or prices rise. Designing out cost is a permanent saving, and this is what Coidan Graphite deliver.

Our systems enable us to deliver on time and to spec, with conformity and origin certified when required.

Our customers are at the heart of everything we do, and we work extremely hard to provide support at all times.

For more than 10 years, we have worked with aerospace companies such as Rolls Royce and Honeywell PLC. We are also proud to be ISO9001:2015 approved.

Graphite materials are used in a range of aerospace applications. Not only is graphite the smart choice in terms of quality, but our graphite is also the greener choice. With aerospace being a growing industry dependent on fossil fuels, organisations have a responsibility to reduce the environmental impact of their industrial processes.

The aerospace industry has changed considerably over the years, but our core values remain the same: providing our clients with unbiased technical advice, a flexible approach and customised solutions to drive savings in production processes.

Our Vision

Our vision has remained the same throughout the years: to build an innovative, global graphite manufacturing company that offers our customers a full range of top quality carbon and graphite-based services. Moving together towards excellence, we aim to build our future, setting Coidan Graphite's standards as the benchmark for the niche carbon and graphite market we occupy.


We are ISO9001:2015 approved and an approved Tier 1 Rolls Royce Nuclear Submarine plc supplier.
