Metal Coated Hollow Ceramic Microspheres

 

Metal coated hollow ceramic spheres enable design engineers to manufacture high strength light weight parts.  Thermal conductivity can be varied and thermal expansion can also be controlled.

 

The Aluminum and Nickel coatings are 99+% pure, and have a consistent thickness.   Complete coverage and adhesion is guaranteed and the coatings are stable in air at room temperature.

 

These coated microspheres can be pressed or forged into light weight structures or substrates.  Parts formed using our microspheres are durable and machinable.  For best results, the powders should be added to other matrix materials (Mg, Al, Ni, Ti, Fe, etc.) in volumes of 10-40% depending upon the properties desired.

 

Typical Coatings

 

Aluminum 10-15 wt%

Nickel 20 wt%

 

Other metal coatings are available on request.
