Five Most ordinarily Used Metals

As much as population love to call it a digital age, the fact is that we still live in the metal age. Despite the invention and over-usage of plastic in most industrial applications, metals still rule manufacturing industries. The whole process of transforming ores into plane shiny surfaces of useful products can be quite expensive and time consuming. Yet, the ability and endurance is unsurpassed by whatever else. There are many fellowships which offer services such as contract slitting, shearing, stamping and Oem slitting.

The usage of metals is not just limited to one industry or area of application, in fact they are used in range of areas including both domestic and industrial. Let us take a look at five of the most ordinarily used metals and their properties.

Five Most ordinarily Used Metals

Iron is the most ordinarily used metal in the world, and probably one the most abundant in the earth's crust. It is also one of the metals found abundantly in the human body. Therefore, it also has medicinal uses as well. One main suspect behind its wide industrial use is its usage in the manufacture of steel, which is one of the strongest and stainless materials. The iron is well known for its even-heating property.

Aluminum:

The most abundant element in the earth's crust is also one of the most ordinarily used in the world. One single suspect behind this is the metal's low density and corrosion resistivity. Its uses vary from every day household usage, such as tin cans and aluminum foils, to heavy industrial and manufacturing applications, such as automobiles and aircraft industry. It is also used in solid rocket fuel and thermite.

Copper:

Being known as one of the earliest metals discovered by man, copper still is among one of the widely used metals in the word. It was also one of the earliest metals to be used for manufacture tools and even coinage. This is because it is ductile and easy to work with. Copper is mostly used in the form of alloys because it is too soft to be used in its pure form. It is a good conductor of heat and electricity. Therefore, it is mostly used in wirings and piping.

Titanium:

Already known as the space age metal, titanium is predicted to replace most of the metals used around the industries today. However, its expensive and difficult mining process is holding it from being used so ordinarily as Aluminum or steel. Titanium is found to be stronger, durable and corrosion resistive in comparison to steel. It has the top vigor to weight ratio of all the metals. All these properties, along with its light weight, make it an ideal metal for spacecrafts and soldiery jets. Typically, it is used in manufacture highly water -resistant diving watches.

Zinc:

Unlike other ordinarily used metals, zinc is hard and brittle. It is anti corrosive, and therefore it is primarily used in galvanization, for example coating of iron and steel. It is also used in batteries along with lead.

History of the Curling Iron

History of the curling iron. Is there such a thing or is the curling iron just a contemporary invention? Each generation is the same. We think we have invented something new when perhaps all we have done is to modify "old inventions" by applying contemporary technology. Let us begin to study the history of the curling iron or, as it is also known, the curling tong.

Let us begin with the definition of a curling iron. It is a tool, a cylindrical metal appliance, used to change the structure of the hair by applying heat to a lock of hair that has been curled colse to it. It is natural to think with a contemporary mind and assume that the heat is generated by electricity. However, the curling iron goes way back before the introduction of electricity.

Used Irons

We only have to look at carvings from the old world to see that habitancy cared about the style of their hair and that a favorite style complex creating curls. Babylonian and Assyrian men dyed their hair and quadrate beards black and crimped and curled them with curling irons. Persian nobles also curled their hair and beards, quite often staining them.

History of the Curling Iron

Egyptian nobles, men and women, cropped their hair close but later, for coolness and cleanliness in their hot climate, shaved their heads. On ceremonial occasions, for protection from the sun, they wore wigs. The wigs would be short and curly or long and full of curls or braids. The Science Museum has an example of curling tongs used by rich Egyptians to get ready their wigs.

In classical Greece it is known that the upper classes used curling irons.

Through time there have been many methods devised to curl hair and to keep the curl in place. For example, in 1906 Charles L. Nessler, a German hairdresser working in London, applied a borax paste and curled hair with an iron to yield the first permanent waves. This costly process took twelve hours. Eight years later, Eugene Sutter adapted the recipe by creating a dryer containing twenty heaters to do the job of waving more efficiently. Sutter was followed by Gaston Boudou, who modified Sutter's dryer and invented an self-acting roller. By 1920, Rambaud, a Paris beautician, had perfected a system of curling and drying permed hair for softer, looser curls by using an electric hot-air dryer, an innovation of the period made by the Racine Universal Motor firm of Racine, Wisconsin. A considerable breakthrough came in 1945, when French chemist Eugene Schueller of L'Oréal laboratories combined the activity of thioglycolic acid with hydrogen peroxide to yield the first cold permanent wave, which was cheaper and faster than the earlier hot processes. To operate the amount of curl, varying diameter of rods were used for rolling. Technology to hold hair in place was advanced in 1960 when L'Oréal laboratories introduced a polymer hair spray to serve as an imperceptible net.

The curling iron has remained a favoured tool in spite of all the chemical inventions. We have moved on from the metal rods heated by insertion into hot coals or heating on gas or electric stoves. With no operate of the heat of the iron there must have been many cases of singed hair, not to mention burnt fingers and scalps! contemporary day styles interrogate more operate and flexibility of hair style with hair finding loose rather than "glued into place". Electrically heated and electronically controlled irons and tongs are now available. The barrels come in varying sizes enabling a tight curl or loose falling curl finish. Some have a smooth easy-glide ceramic barrel to create a super smooth close and you can also purchase drop curl hair tongs with a cone shaped tong to create loose, tumbling waves and tousled curls. The fluctuation in hair styles from curly to straight and back again means manufacturers will continue to dream up new innovations to attract both pro hair stylists and the consumer.

So who "invented" the curling iron? Inevitably you find many references to "invented" and "patented by" or "introduced by". The former creator is lost in the mists of time but examples of the old sentence are:

In1866, Hiram Maxim, who designed the motor gun bearing his name, applied for and obtained the first of many patents at age 26 for a hair-curling iron.

Four years later in 1890 two Frenchmen, Maurice Lentheric and Marcel Grateau, used hot-air drying and heated curling tongs to make deep, long-lasting Marcel waves.

The Straightening comb however, is really credited as first being invented by the late 19th century French hairdresser, Marcel Grateau, who also, invented the curling iron, the permanent wave and later the Gillette protection razor which became favorite in Germany after World War I.

In related developments, Rene Lelievre and Roger Lemoine invented an electric curling iron in 1959.

The pressing/curling iron was patented by Theora Stephens on October 21, 1980.

In August 1987 the Wahl Clipper Corporation introduced to the pro shop the ZeeCurl. This flat-barrel curling iron gave stylists a tool to create new hairstyles with Z-shaped curls, adding texture and body to all types of hair. In 1988, FrenZee, the consumer version, was added.

There is little doubt that fashion will interrogate and dictate new innovations to ensure continuation of the history of the curling iron.
