1. The metals also vary in hardness, from potassium, which can be molded like wax, to chromium, which will cut glass. 2. The metals and other substances differ in the extent to which they can resist a strain that tends to bring about a permanent change in their form. 3. All substances offer more or less resistance to the flow of an electric current through them. 4. With any given substance, the resistance is determined by its dimensions and the temperature.5..The solids obtained when two or more metals are mixed in the molten condition and allowed to solidify are called alloys. 6. Each constituent of an alloy is called a component. 7.Alloys may be binary (two-component), ternary (three-component), etc. 8..The ability of various metals to form alloys differs greatly.

ALUMINIUM

1.Aluminium, whichis sometimes called aluminum.2. It is the typical metal in the third group in the periodic classification of the elements. 3. Aluminium is the most abundantof the metals and the most widely distributed.4. It is found in feldspars, micas, kaolin, clay, bauxite, cryolite, alunite, corundum and certain gems.5. Compounds of aluminium have been known for many years and they were recognized as being derived from a metal that hadnot beenisolated.6.Aluminium has a very low density; 2.7; 7.It is used in construction when a metal is required and weight is an important consideration. 8.It is ductile, malleable, and can be rolled.

9.Its tensile strength is low in comparison with that of iron;10. It cannot be machined and polished readily and does not yield good castings. 11.These defects can be overcome by alloying it with other metals.

I.Read and translate the text.

1.Copper was used in prehistoric times for making weapons and tools 2. Later it was alloyed with tin to form bronze, which was the most important metal of the Greeks and Romans.3 It was replaced for these purposes by iron and steel. 4. Various grades of copper are used for engineering purposes. 5. The great development of the electric industries has resulted in such extensive uses of the metal.6. It now ranks next to iron in importance.7. The copper alloys are more widely employed. 8. The alloying of copper with other elements increases the strength of the metal in some cases and improves the anticorrosive and antifriction properties in others.

9. Copper alloys comprise two main groups — brasses and bronzes. 10.Alloys of copper and zinc are called brasses. 11.Alloys of copper with a number of elements including tin, aluminium, manganese, iron and beryllium are called bronzes.
