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...
Apple Inc. is in a deal of getting an exclusively strong, exotic and glossy metallic metal that will provide its computers and phone casings with a shiny and strong exterior.Liquidmetal Technologies Inc., which is a Caltech spinoff in Rancho Santa Margarita, Calif., filed a regulatory notice recently...
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...
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...
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....
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...
15. LHC The chances of the Large Hadron Collider actually producing a miniature black hole—or anything life threatening for that matter—are so small as to be minute. Like, crazy minute. As in, will probably never happen so minute. And even if the LHC does start producing tiny little baby black...
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...
There are actually two different kinds of tapes that are commonly referred to as plumber’s tape. One type of tape should be more appropriately called Teflon tape. The other type of plumber’s tape, on the other hand, should be called metal strapping instead. In either case, each type of tape is more...
