It is not easy to define what a metal is. Physically, a metal is a substance that has a bright luster and is a good conductor of heat and electricity. Metals have varying degrees of hardness, density, malleability and ductility. (Malleability concerns being able
to be rolled Out and hammered. Ductility has to do with being drawn out, as into wire.)
Metal has a definite melting point and will fuse with other metals to form "alloys". With the exception of mercury, all metals are solids at ordinary temperatures.
Some metals are found in the pure state, but most of them are found in combination with other elements. These metals arc in the form of sulphides, oxides, carbonates, and silicates, usually mixed with rock and earthy materials. Some of the common metals found in combination in ores are lead, zinc, iron, copper, chromium, nickel, and mercury.
Some metals are so rare that tons of ore must be treated to get even a small amount of the pure metal. Radium is one of these. The science of recovering metals from their ores is called ''metallurgy".
Many metals, when they are in the pure state, have properties that are undesirable. This is why most of the metals commonly used today are either alloys or compounds. Examples of alloys are table silver, gold coins, and aluminium pans. Pure iron is too soft to be of much value, so it is used most frequently as steel, which is a compound.There are a few metals which, in tiny amounts, are necessary to animal life. Among these are iron, potassium, calcium, magnesium, and sodium. The body even uses minute quantities of copper, aluminium, and manganese
There are several different types of metal, some are worth more than others. I'm only going to speak on what I do know to be fact. There is silver, gold, copper, brass,and aluminum, brass, and stainless steel. All of these I have listed are non-magnetic,and have a dollar value to them, varying in value amount. There is also, pewter, galvanized,and a few others that I'm not sure, about. I was taught if a magnet does not stick to it , there is value to it.
I hope this info., will help assist you.
Metal is a chemical element. The most famous kinds of metal are copper steel aluminum and iron. The strongest kind of metal KNOWN is, of course, titanium. Some ways to determine what kind of metal it is is by looking at the METAL'S properties such as color texture luster and hardness.
Ferrous and non ferrous ferrous contain iron, non ferrous don't
A metal is a substance and which conducts current and heat
Metal are the elements having following properties
Differnet metal depends of the type of forging they do. Whatever metal is used also de ponds of the bonding of that type. What type of bonding you want is up the the certain forging company or metal company depending on your job. Do to that knowlege you will and/or benifit from they metal that is called 4120, 9610, d10, m12 and there is so much more. Metal is complicated do to its bonding and holding depending on what your doing with is as for ex: If you carburize 9610 to .100 to .120 case depth you need to freeze that type of metal to bring the retained austenite out of it and then temper it. So as I was saying the metallurgy is way to complicated to actually understand metal. You need to reserch it more complicated to acctually undersatnd what you are asking.
Alkali metals are valuable both in living organisms and as structural materials.
Need to know all differnt types of metal and gages of rolled pipe, used for fencing and fabrication
We differ them by looking at them

Principle properties specification of metal?
It is a bra which the ladies wear after taking bath to cover the organs with they had once fed their babies. Liked it?hahahahahaha.
