It is malleable, ductile, and a good conductor of electricity and heat. Copper is a reddish brown metal ; Applications of Copper: For making electrical cables. The strength and hardness of copper can also be increased by alloying, but this results in a decrease in electrical conductivity. Copper has many extremely useful properties, including: good electrical conductivity; good thermal conductivity; corrosion resistance; It is also: easy to alloy; hygienic; easily joined Heat exchangers; For making various copper alloys, such as bronze and brass. The material condition (alternative term: temper) is designated in standards either by the letter H, representing a minimum hardness,  or the letter R, representing a minimum tensile strength. In this work, copper/bronze laminates with varying interface spacing were fabricated by accumulative roll bonding and subsequent annealing to systematically study the interface effect on mechanical properties. Metal properties like steel yield strength, density, hardness and other parameters are important factors when designing a mechanical part or selecting the right material for CNC machining services, here we present a simple table of properties of some common metals and detailed metal mechanical properties … Conducting electricity.
