The matrix materials of the composite materials are divided into two main categories of metal and nonmetal. Commonly used metal substrates are aluminum, magnesium, copper, titanium and alloys thereof. The non-metal matrix mainly comprises synthetic resin, rubber, ceramic, graphite, carbon and the like. The reinforced material mainly comprises glass fiber, carbon fiber, boron fiber, aramid fiber, silicon carbide fiber, asbestos fiber, whisker and metal. Copper alloys (copper alloys) are alloys based on pure copper with one or several other elements added to the copper. The pure copper is purple red, and is also called as red copper. The pure copper with the density of 8.96 and the melting point of 1083 ℃ has excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance. The method is mainly used for manufacturing electrical equipment such as a generator, a bus, a cable, a switching device and a transformer, and heat-conducting equipment such as a heat exchanger, a pipeline and a flat plate collector of a solar heating device.
