Alloy Wheels and tyres for the Strong and Sturdy Make
The term alloy generally implies a mix of two or three elements that are combined to produce a material of increased durability and strength. These compounds are typically similar in strength when compared to the parent compound although much lighter in nature. However, this alloy wheels and tyres exhibits better conduction and cosmetic nature when compared to normal wheels.
The first ever made alloy wheels and tyres were primarily magnesium alloy. Although this wheels lost popularity amongst common vehicles, they still remained in vogue until the 1960s for a limited number of vehicles. At this point of time, this wheels were little ductile exhibiting an elongation range of up to only 2-3 percent.
This wheels during the earlier phases of its production was referred to as the “mags” due to its production from magnesium, but later was more of aluminum based alloys. The main feature of these wheels is that, they can retain the suspension for a longer period of time and thus are lighter in their nature when compared to their steel based counter parts. Also, there is a reduction in the overall body mass of the vehicle when implanted with alloy wheels when compared to normal wheels and thus, it is an apparent reduction in the amount of fuel that is actually being consumed.
Despite all these advantages, these wheels are susceptible to galvanic corrosion, which results in the leakage of air when proper measures are not taken. Besides that aspect, alloy wheels are more difficult to treat and maintain when compared to steel wheels, but due to the higher cost that is involved, mostly repairs are preferred over replacement. Hence for those who prefer to have their alloy wheels replaced, it is always wise to think twice because of the cost that is actually involved in replacing their alloy wheels.
Today, despite the fact that magnesium based wheels are mostly not found on cars, it is exclusive for a few cars that
actually use magnesium based alloys to produce much larger wheels and tires. Although magnesium based alloy wheels are mostly used for the purpose of racing, their usage led to the development of dye cast wheels such as the aluminum alloys. These magnesium based wheels are produced by means of a technique called as forging, which impart the properties of toughness and ductile nature to these wheels, although the costs that are involved in the manufacture are much higher.
Besides forging, there are many methods to produce these alloy wheels. High Pressure die casting is one such method that employs a filler tube to pour the molten magnesium, which is referred to as a shot sleeve. Low pressure casting is yet another method that employs the usage of a crucible that is filled with magnesium. With all these methods, it has been noted that low pressure die casting method offers maximum ductile quality when compared to the high casting die methods. Thus, apart from the methods produced, it is apt to state that this wheels are definitely a big boon in the automobile industry, when it comes to the point of durability, tensile strength and fuel economy.
