Metal has been around for many centuries. It is valued for its strength, versatility, electrical conductivity and durability. It can be used in both architectural and industrial fabrication projects and in many other ways. Approximately 75 percent of all the elements on the periodic table are some type of metal.
Not only is metal used in various types of building and industrial projects, but there is also an entire metal machining industry. Here you can learn some interesting facts about metal you may have never known.
Iron – It’s Everywhere
According to scientists, iron is the most abundant metal on the planet. It is also what makes up the core of the Earth. However, when it comes to the Earth’s crust, the most common metal present is aluminum. Both iron and aluminum are used in metal machining and fabrication processes.
While you may know that iron is a strong and durable metal, there may be a few facts you don’t know about this metal. For example, to galvanize metal, it has to be dipped in molten zinc. This process helps to prevent the development of rust.
Silver, Gold and Other Precious Metals
Platinum, gold and silver are known as the noble or precious metals. There are some unique characteristics of these metals that aren’t present in other types. For example, silver will conduct electricity much better than other types of metal. Also, all of the precious metals can resist corrosion and oxidation when the air is moist.
The Strength of Steel
Approximately 69% of all steel, which represents more than 80 million tons, is recycled each year in North America. That is more than all the glass, plastic, paper and aluminum combined. The magnetic properties of steel make it easy to separate from the other solid waste and put it into the recycling stream.
As you can see, there are quite a few interesting facts about metal. Knowing this information may help when you have plans for a metal fabrication or metal machining process.
