Nano-Metal Coating to Improve Durability of Composite Tooling

19 February 2007

Integran Technologies has developed Nanovar, a low thermal expansion, hard metal coating to improve the durability and extend the lifespan of composite tooling.

Integran say that their material is nano-structured, meaning the metal grains are 1000x smaller than conventional metals, resulting in hardness similar to a tool steel. Adhesion through repeated thermal cycling is achieved by closely matching the thermal expansion of Nanovar to the carbon composite substrate.

“The composites manufacturing industry has waited a long time for a product like this.” says Rich Emrich, Program Manager at Integran Technologies. “Nanovar enables companies to take full advantage of lightweight, low thermal mass composite tooling in a volume manufacturing environment”.
