Although lithium metal has been available for 60 years, very little use has been made of it in metallurgical applications until recently. The first reported use was in 1918, when German metallurgists utilized it as an alloying element in the production of Scleron, an aluminum-zinc alloy containing 0.1% lithium. 

Aluminum and aluminum-zinc alloy anodes have become the preferred sacrificial anodes for the cathodic protection of offshore platforms. This preference is because aluminum anodes demonstrate reliable long-term performance when compared with magnesium, which might be consumed before the platform has served its useful hfe. Aluminum also has better current/weight characteristics than zinc. Weight can be a major consideration for large offshore platforms. The major disadvantage of aluminum for some applications, for example, the protection of painted ship hulls, is that aluminum is too corrosion resistant in many environments. Aluminum alloys will not corrode reliably onshore or in freshwater [37]. In marine... 

PURPOSE OP EXPERIMENT Determine the percent composition of an aluminum-zinc alloy by measuring the H2 formed upon reaction with acid. 

In this experiment you will react a weighed sample of an aluminum-zinc alloy of unknown composition with hydrochloric acid and collect the hydrogen gas that is formed. The number of moles of hydrogen formed can be calculated from the volume, partial pressure of H2, and temperature of the gas sample. Using this data, the percent composition of the alloy can be calculated. 

Hot dipping is carried out by immersing the metal on which the coating is to be applied, usually steel, in a bath of the molten metal that is to constitute the coating, most commonly zinc, but also aluminum and aluminum-zinc alloys. Hot dipping can be either a continuous process, as in galvanizing steel sheet, or a batch process— for example, galvanizing fabricated parts, nuts, bolts, and fasteners [1].
