Metal Matrix Composites
Matrix Metal Composites are not so very much used for making frames.
Specailized is the first manufacturer, which applies a aluminum alloy containing 10% aluminum oxide on a large scale.
The great advantage of the addition of aluminum oxide is the higher stiffness and greater resistance to wear.
The expropriation for a public collective name of such materials is metal-matrix composites.
They consist of an alloy of metal and ceramic fibers (usually silicon carbide, or aluminum oxide).
By the addition of the ceramic fiber can be increased, the strength, wear resistance and rigidity.
Because the material is relatively new, the editing features are still in development and the material is expensive.
