many metallic materials are alloys, or mixtures of two or more metals. for example, brass is an alloy...?
copper has a density about 8.9 g/cm^3 zinc has a density of about 7.1 g/cm^3 brass should have the density between 7.1 to 8.9. it is higher than zinc, lower than copper.
i want to know the reasons that pure aluminium and copper are classified as easy to machine materials?
*The easiest of the coppers to machine are the special free machining grades which approach the ease of machining of the standard brass. The machining properties of all the materials vary and it is suggested that for best results the tool angles, cut...
what are the differences in oxidation of pure metals and alloys?
in oxidation of alloys there is some kinds of metals . first one of them that has great affinity with oxygeon, is combined then other metals oxidised. every metal that releases greater energy it is combined earlier.but in pure metals we encounter wit...
