Physical Properties of Copper

All of us know what copper is, as we use various goods made from copper in our every day life. Scientifically, it is known to be a chemical element which is present in the periodic table as Cu with the atomic number 29. Copper has been a very useful metal since ancient times and people have made use of it in constructive ways to make utensils, currency coins, constructions, etc. It is a metal which is extracted from mines and is then processed into usable forms. There are a number of common physical and chemical properties of copper which are also used in a variety of ways around the globe. In this article, we will be discussing some of the main physical properties of copper which are more commonly used than the chemical ones. So, read on and find out what these major properties are, from the paragraphs mentioned below.

Copper Physical Properties

As mentioned earlier, there are a few physical and chemical properties of copper which are used for many purposes. There are many uses of copper and its alloys in many preparations as core metals. This is mainly because these properties are very essential and they provide the flexibility to change the form of copper in any desired manner. When pure copper is mined out, it has a reddish orange color to it, but due to its physical properties, it may react with oxygen to give a unique color change. Copper also can alter its color due to the tendency to reflect light in the red spectrum of colors. The physical properties of copper are discussed in the coming up paragraphs, for your convenience, take a look.

Malleability
The first and the most important properties of copper is that it is malleable and ductile. Though these two properties are not the same, they can be correlated to some extent. Malleability is defined as the property of a metal or solid to be hammered and bent in various shapes without breaking or cracking used to make thin sheets out of copper.

Ductility
Ductility refers to the extent to which the metal can be deformed without taking stress and without breaking. This can be used to make thin wires of the metal. The physical properties of copper wire are that it can be twisted and molded in any direction. The melting point of copper is 1,083 degree C (1,982 degree F) and a boiling point of 2,595 degree C (4,703 degree F). It is found in all the three states of metal.

Conductivity
Another property of copper are that it has a high thermal and a high electrical conductivity. After silver, it is the second best electric conductor found in nature. In the pure form, the conductivity is even more efficient and hence, utensils and cook wear is best made form copper. It is also a very important metal used in refrigerators and radiators, since the transfer of electricity and heat can be very fast with this metal. This is surely the most important one of the three physical properties of copper that are majorly used.

Corrosion Resistant
Copper is also resistant to corrosion, which means it can withstand environmental changes that lead to rusting and corrosion. If it is left in contact with moisture for a very long time, the only change that is observed is the change in its color from the usual reddish orange to reddish brown. If you have ever wondered, why does copper oxidize and turn green it is because this green film prevents any further corrosion. This is why it is also a very durable metal.

Alloy Formation
Copper is a metal which has the highest ability to mix with other metals to form alloys. It also has the maximum number of alloys with a variety of metals and all of them are used for some or the other purposes. These different types of alloys have the highest resistance to corrosion as mentioned above, and are very effective in their products, bronze and brass being two of the most traditional copper alloys made. More than using copper in its pure forms, it is used in the form of alloys as they too have a few useful properties which can be used.

With these significant physical properties of copper, I am sure you have learned some important points about this fantastic creation of nature. Copper is one metal which is very useful, readily available and can be used in any form, so make the most out of it.
