The term bullion refers to precious metals that are in bulk form. A metal is considered precious if it is naturally occurring, rare, and of high value, economically speaking. The value of the bullion comes from the metal itself, not from the assigned currency value. Looking back in time, these...
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...
What we call “rust” scientists call “oxidation.” It’s what happens when metal are exposed to oxygen for long periods of time. Eventually, the oxygen molecules “bond” with the metal molecules, creating a new compound called oxide. The metal becomes weaker. Rust-encrusted iron or steel is called iron...
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....

Zinc is a kind of metallic chemical element. It is considered to be a transition metal, similar to nickel and mercury. It has the chemical symbol of ZN with an atomic number of 30. 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...
A resistor is one of the most important parts of an electrical circuit. As its name implies, it “resists” the electricity, which courses through its two terminals. The resistor then lowers the voltage to safe levels. Resistance can be quantified and measured in ohms (which borrows its name from...
The ethmoid or ethmoidal bone is a pnumatized part of the human skull, technically one of the pieces that make-up the neurocranium. It constitutes to portions of the nasal cavity, cranium floor, and eye sockets. Pnumatized bone are bones that have air-filled cavities, making them much lighter when...
