What we call “rust” scientists call “oxidation.” It’s what happens when metal are exposed to oxygen for long periods of time.

Gold is one of the best conducting metals known to mankind. It's also nearly impervious to sulfuric acid due to its nearly unique chemical nature. As if this wasn't enough, gold can be hammered down to only one atom of thickness and worked like clay in its pure state. The physical characteristics...
EDM or electrical discharge machining, is a type of machining method that is often used when working with hard metals or those that will be extremely hard to machine with normal techniques. A big limitation of EDM though is that it can only be used with materials that can conduct electricity. EDM...
When it comes to classifying stainless steel as having magnetic properties, there is not a simple yes and no answer. Instead, the proper response would be to state that it depends. Here is some information about stainless steel that will help to identify situations in which this alloy exhibits...
Have you heard of the superstition, “if you find a penny you will have good luck“? Everybody has probably heard about this because it has been around for many years. Some ancient people say that metal was a gift from God for protection. This is why people believe that metals and coins are lucky....

In its pure form it has a kind of light blue color. It tends to be quite brittle at room temperature but, once it is...
Anodizing is a process that gives metals a stronger surface. Anodizing is usually done by immersing a metal, for example, aluminum, in a bath filled with sulfuric acid. This bath is an electrolyte and a low voltage electric current runs through this acid bath. The electric current allows for the...
