Technical Report The Construction of Alloy Wheels creationAluminium anyoy wheels are now recitationd in all branches of Motor Racing,ranging from Touring cars and Rally cars to Formula One cars. TheAlloy wheels offer ut around superior mechanical properties than theconventional steel wheels formerly employ. These benefits include cut un-sprung weight, i.e. not held by the suspension, providingmore precise steering input and modify responsiveness.Alloy wheels also improve acceleration and braking due to thereduction of weight. The added strength of a quality debasement wheel cansignificantly turn off wheel/tire deflection in cornering. This isparticularly critical with a vehicle equipped with high performancetires where lateral forces may approaching 1.0g. The metals in alloywheels are excellent conductors of wake - improving heat dissipationfrom the brakes - reducing risk of brake fade chthonic demandingconditions. Additionally, alloy wheels can be designed to allow more p edigree to flow over the brakes, this can help cooling.The alloy used in the finest road wheels today is a blend of aluminiumand other elements. The terminal mag wheel is sometimes incorrectly usedto describe alloy wheels. Magnesium is generally considered to be anunsuitable alloy for road system due to its brittle nature andsusceptibility to corrosion.Nowadays, there are essentially 3 ways in which alloy automotivewheels are constructed. The three types can be referred to simply bycast, billet and forged. roll is a relatively inexpensive way to produce a high-quality,fairly industrial-strength alloy wheel many aftermarket alloy wheels designed forstreet use are made this way. Billet wheels are machined from a solid testicle of material and forging uses intense heat and pressure totransform a slug of alloy material into the final shape of a wheel.This narrative will focus mainly on the form processes used.Casting ProcessesThe most common process of constructing alloy wheels i s One-PieceCasting, there are a number of methods to do this, and the most basicis Die Casting, this process is used world wide throughout the castingindustry and is not scoop shovel to alloy wheels.The Die Casting process uses a permanent work out usually made of metal,which generally means that there is high tooling be compared toother methods of casting, but this high tooling cost is combined withlow product costs. This means that die casting is suitable forproducts with a large work number.There are four main processes in the die casting family, these are sedateness Die CastingPressure Die CastingLow Pressure Die CastingSqueeze CastingGravity Die CastingThis process is the most simple of the four, the mould or die, whichis generally made in two halves, is filled with molten metal, in the
