The metal material with the highest copper content is called pure copper. It is also commonly known as red copper because of its surface appears reddish-purple colour. Copper has a high degree of flexibility and ductility.
Brass is an alloy of copper and zinc, which is commonly known as brass because of its golden yellow surface colour. The zinc in brass makes the material harder and more resistant to abrasion, while the material also has a good tensile strength.
Bronze is an alloy material made by melting copper with some other rare or precious metals. Different combinations of alloys have different physical properties and applications.
Beryllium Copper Foil is one kind of supersaturated solid solution copper alloy which combined very good mechanical ,physical, chemical properties and corrosion resistance.
The copper-nickel alloy material is commonly referred to as white copper because of its silvery white surface. copper-nickel alloy is an alloy metal with a high resistivity and is generally used as an impedance material. It has a low resistivity temperature coefficient and a medium resistivity (resistivity of 0.48μΩ·m).
