Copper

Copper and its alloys are the oldest conducting metals that have high conductivity, good ductility, great strength, malleability, and high corrosion resistance making it the most widely used metal all over the world.

Overview of Copper And Its Alloys.
Copper is a type of transition metal that belongs to the d block of the periodic table and has face-centered cubic structure (FCC). Copper is the oldest metal that has been found on Earth and is widely used for several applications. Copper exists in its pure form in nature so can be easily available for use. Copper tends to easily form alloys with other metals like tin, aluminum, zinc, phosphorous, beryllium, nickel, etc.

Alloys of copper exist in many forms and some of the main alloys are bronze, brass, copper-nickel (cupronickel), nickel silver alloys, etc. which are used for various purposes at the commercial level. Some of the main properties of copper and its alloys involve excellent electrical and thermal conductivity, magnificent corrosion resistance, superb machinability, etc.

Copper and its alloys have a wide range of potential applications in consumer products, transportation, building industry, industrial machinery, and electronic products. Some application involves cooking utensils, electrical wires, and cables, copper pipes, plumbing, roofing on buildings, refrigeration tubing, and sculptures.

Properties and types of copper alloys.
Copper is a widely used conducting metal with many extraordinary properties which make this metal and its alloys fit in several applications with great potential. Following are some major properties of copper and its alloys:
• It has excellent electrical conductivity
• It has outstanding heat conductivity
• It gives very good corrosion resistance
• It is having superb machinability
• It is having good bio fouling resistance
• Copper and its alloys are non-magnetic
• It is having a high electrical and mechanical properties retention rate
• Having a high recycling rate

As compared to other metals, copper can form alloys more easily in a wide range. Some of the main alloys of copper are:
• Brass: These alloys of copper are formed by mixing copper and zinc and are referred to as a range of wrought and cast alloys of copper. These alloys are rich in properties like high ductility, good mechanical strength, and effective thermal, and electrical conductivity.
• Bronzes: Bronze is an alloy of copper and tin and this was the very first alloy of copper that was obtained 4000 years ago. They come in different types as tin bronze and phosphor bronze used in springs, shafts, and bearings; aluminium bronze used in seawater applications; silicon bronze and manganese bronze used for architectural purposes.
• Copper-nickel: These are types of copper alloys made by mixing nickel to copper which increases corrosion resistance, strength, and ductility retention. These alloys are used for several applications.
• Copper Beryllium alloys: These are the strongest and hardest among all alloys of copper with superb mechanical properties and excellent strength and good corrosion resistance. These alloys have applications in the petrochemical and mining gas industries.
