Metals’ Properties
A). Metals are any substance that conducts electricity and heat well, is shiny (exhibits what is called metallic luster), is opaque, can be made very strong by proper alloying and other techniques, and can be readily formed by rolling, drawing, and cutting. More than 75% of the elements are metals. Metals have crystal structure. An atom in a metal is usually closely surrounded by a large number of other atoms.
B). Metalloid is a material having properties of both metals and nonmetals. Most metalloids have the physical appearance and luster of metals, yet are brittle and are poor conductors of heat and electricity at room temperatures (as are most nonmetallic materials). Included among the metalloid elements are germanium, silicon, arsenic, antimony, boron, and tellurium. In addition, the rare elements astatine and polonium are sometimes considered metalloids.
Thousands of compounds are metalloids.
C). Metals do not have to be pure elements. Some compounds, such as tantalum carbide, are also metals. Alloys are combinations. For example, copper and zinc, melted together in the proper proportions and solidified, form the alloy brass. Brass is neither a mixture nor a compound but a solution having the same crystal structure as the base metal, copper. Alloying usually decreases electrical conductivity.
Metals have a wide range of densities, varying from one-half gram per cubic centimeter (0.5 g/cm3) for lithium to 22.5 g/cm' for osmium, the densest material known. The melting points of metallic elements vary from -38.0° F (-38.9° C) for mercury to 6170° F (3410° C) for tungsten, while hafnium carbide melts at 8312° F (4600° C).
Metals can be highly reactive (cesium oxidizes and reacts violently with chlorine). They can also be highly resistant to oxidation (gold) or to attack by strong acids (gold, tantalum, stainless steel).
D). Steel. Carbon steel is the most common as the cheapest and most versatile metal used in industry. It has excellent ductility, permitting many cold-forming operations. Steel is also the most weldable of all commercial metals. It is two-thirds the weight of lead, three times heavier than aluminium.The corrosion resistance of steel depends upon the formation of an oxide surface film. However, resistance to corrosion is somewhat limited. Carbon steel should not be used in contact with dilute acids. Between 90 and 98 per cent, steel can be used up to the boiling point.
