Hybrid material. Hybrid materials are composites consisting of two constituents at the nanometer or molecular level. Commonly one of these compounds is inorganic and the other one organic in nature. Thus, they differ from traditional composites where the constituents are at the macroscopic (micrometer to millimeter) level.
Best Answer: An alloy is a homogeneous mixture (solution) of two or more metals. A composite material is often heterogeneous, and is not always of metals. Example of Composite Material: Concrete and Fiberglass. It is material composed of more than one material, they are mixed but not in a homogeneous form. Example of Alloy: Steel and Copper. It is made of more than one material also, but they are well mixed, usually metals are melted and mixed together to give an alloy.
