Copper is a strong and valued metal that helps to allow our society to run smoothly. Since the early 1800s, this type of metal has been used in electrical wiring. This was possible as a result of the creation of the electromagnet in the 1820s. Copper began to pick up in popularity at the time, and it was even used to help create the telegraph. In the mid 1870s, Mr. Alexander Graham Bell created the telephone, and this greatly increased the markets need for copper wiring.
The benefits of copper wire are proven throughout many different industries. This includes:
- Power generation
- Power transmission
- Power distribution
- Circuitry of electronics
There are several more applications that copper can be used for.
There are a lot of boons to be had when dealing with copper wiring, and this is because of all the different positive properties of copper.
For starters, copper has an extremely high electrical conductivity. Electrical conductivity is defined as the amount of electrical charge that is transported through an object. High conductivity means that electricity can easily flow through the metal. In fact, copper has the highest conductivity out of all non-precious metals. Aluminum only matches 60% of the conductivity that copper provides, and silver, which is a precious metal, is the only metal that can compete at copper’s level of conductivity.
Another positive feature is the tensile strength of copper. Tensile strength is the amount of energy needed to pull another object (usually rope, wire, or sheet materials). When something has reached its tensile strength, it will break or snap. Copper has a tensile rate of 200-250 N/mm2. Copper is stronger than aluminum, and it only has a strength rating of 100 N/mm2). Considering the tensile strength of copper, you will find it being used in the building industry.
Copper is also ductile. Something that has ductility is something that can be molded and deformed without breaking, chipping, or scratching. This process is important in metalworking because products get hammered, rolled, and drawn. Copper has ductility.
These are just some of the strengths that copper can boast. It also has: high corrosion resistance, creep resistance, and thermal conductivity. Copper is easy to install, and it also has high solderability. There are different types of metal alloys, and each adds its own different abilities. For instance, beryllium copper wire does an amazing job at resisting non-oxidizing acids.
