Metal-coated hollow ceramic spheres enable design engineers to manufacture high-strength, lightweight parts. Thermal conductivity can be varied, and thermal expansion can also be controlled. The aluminum, magnesium 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 lightweight structures or substrates. Lightweight Mg-coated hollow ceramic spheres can be used to produce structures 20-40% lighter than Beryllium and 40-50% lighter than aluminum. Visit
