A component made of an aluminum wrought alloy by thixoforging is illustrated in Figure 27. The forging has a very complex geometry but it was reproducible very accurately. The thick-walled component regions as well as parts with essential differences in wall thickness are characterized by a homogeneous structure free of voids.

Tin is used in various industrial appHcations as cast and wrought forms obtained by rolling, drawing, extmsion, atomizing, and casting tinplate, ie, low carbon steel sheet or strip roUed to 0.15—0.25 mm thick and thinly coated with pure tin tin coatings and tin alloy coatings appHed to fabricated articles (as opposed to sheet or strip) of steel, cast iron, copper, copper-base alloys, and aluminum tin alloys and tin compounds. 

Aluminum alloys can be divided into three classes aluminum of various degrees of purity wrought alloys and casting alloys. 

Zinc alloys are available as die-casting alloys or wrought alloys. The sprincipal alloys used for die casting contain low percentages of magnesium, from 3.5 to 4.3% aluminum, and carefully controlled amounts of iron, lead, cadmium, and tin. 

These are available as (i) cast alloys and (ii) wrought alloys. The two major cast alloy systems are 2-10% A1 with minor amounts of Zn and Mn, and Mg alloyed with rare earths, zinc, thorium, and silver without aluminum. The alloys devoid of zirconium are satisfactory in performance in the temperature range 95-120°C. The alloys containing zirconium have better high-temperature properties. Heat-treatment of the cast alloys results in improved properties. 

For aluminum alloy the chip formation depends on the strength of the material. Softer grades of wrought alloy have ribbon and snarled chips, while for harder grades cylindrical helical chips are fotmd (Kammer 2003). 

Anodizing is an electrolytic passivation process that increases the thickness of natural oxide layers on the surface of metals [13]. It basically forms an anodic oxide finish on a metal s surface to increase corrosion resistance. For the anodizing process, the metal to be treated serves as the anode (positive electrode, where electrons are lost) of an electrical circuit. Anodized films are most often applied to protect aluminum alloys. An aluminum alloy is seen on the front bicycle wheel in Fig. 2 [14]. For these alloys, aluminum is the predominant metal. It typically forms an alloy with the following elements copper, magnesium, manganese, silicon, tin, and zinc [15]. Two main classifications for these alloys are casting alloys and wrought alloys, both of which can be either heat treatable or non-heat treatable. 

Almost 85 % of aluminum is used for wrought products such as rolled plates, foils, and extrusions [16]. Cast aluminum alloys provide cost-effective products but usually have lower tensile strengths than those of wrought alloys. Aluminum alloys are used in engineering, the aerospace industry, and for components where corrosion resistance or light weight is needed. If left unprotected their surfaces are anodized, which means that they form a white protective layer of the corrosion product, aluminum oxide.
