What is the difference between forged and alloy wheels?
|specifications :||FORGED WHEELS||ALLOY WHEELS|
|Production technology||The wheel blank becomes forged after being pressed with force10,000 tons per sq. see, as a result, the metal acquires the necessary strength (it becomes stronger than steel) and the structure of the metal changes (it becomes fine-grained and fibrous). Thus, in the workpieces, there simply cannot physically remain voids that could lead to cracks. After machining, the workpiece is reduced in weight by an average of 40 kg.||An aluminum alloy is pressed into the wheel mold made of high-strength steel, the cast aluminum hardens in 7-10 minutes, after which the mold automatically opens and the wheel is immersed in water, a 12-hour heat treatment takes place to increase strength. Further, excess metal is removed on a CNC machine, after which quality compliance tests (balance, tightness) are carried out. Then the wheel is subjected to mechanical treatment to eliminate irregularities, excess metal beads and other defects formed during the solidification process.|
|Service life||Forged aluminum is much less susceptible to corrosion, the structure of the metal does not change over the years, it is possible to use it without paint and varnish, so the wheels can last longer than the car.||They are prone to corrosion and therefore require additional processing and multi-layer painting with varnish coating. But when used in the winter with reagents, they can lose their attractiveness.|
|Weight||Due to the increased strength, forged wheels can be made with a smaller wall thickness than cast ones. The production technology makes it possible to make the weight of forged wheels much less than that of cast ones. The difference in weight between cast and forged wheels with the same parameters can reach 40%.||Alloy wheels of the same model and the same parameters, due to the presence of air in the metal, may slightly differ in weight, but this is unacceptable in forged wheels. In order for alloy wheels to be fracture-proof, in view of the technological features of their manufacture, manufacturers have to make their walls sufficiently massive and thick. This makes it possible to give the structure of the cast wheel the required rigidity for operation, as a result, an increase in the weight of the wheel is inevitable.|
|Dynamics||By reducing the weight and the possibility of producing wheels with optimal parameters, it is possible to improve the dynamics of the car, as well as shorten the braking distance.||Depends on the correct selection of parameters.|
|Handling||By reducing the unsprang weight, you can maintain and even improve the dynamics, while achieving a high ride comfort. Manufacturing according to individual parameters eliminates the slightest discrepancy.||Properly selected parameters contribute to better handling.|
|Exploitation||Resistance to various types of damage makes it possible not to worry about the road surface.||The service life directly depends on the quality of the road surface.|
|Impact resistance||Forged aluminum is much stronger. Wheels withstand mechanical stress better, and dents can form on them with strong impacts. Unlike alloy wheels, forged wheels can almost always be repaired after damage using the method of rolling on a special machine in case of deformation.||Alloy wheels are much more fragile. This is due to increased grain size. When hitting a cast wheel, there is a possibility of a crack on it, which will grow over time under load, vibrations, impacts, thereby reducing traffic safety.|
|Maintainability||They do not split when hit into a hole, so the suspension receives the main impact energy. The ability to repair damage of any kind is much higher than that of cast ones.||If it falls into a large hole, the wheel rim may crack. A split wheels cannot be recovered and must be replaced. The possibility of repair depends on the nature of the damage.|
|Wheel permissible load||When creating and developing 3D layouts, the technical indicators of the forged wheels are calculated, which will be confirmed empirically. The metal structure created by the press makes it possible to make the maximum permissible load much higher than that of cast ones, despite the fact that the spokes can be much thinner.||Alloy wheels for standard civil cars are most often suitable according to the MAX LOAD indicator, but if the car is planned to be used in extreme conditions (off-road, extreme speed, an increase in the standard weight of a car), then it is almost impossible to determine the guarantee of strength and wear.|
|Design||It is possible to manufacture absolutely any design.||The choice is limited to the manufacturers' designs.|
|Options||Standard and customized.||Limited by the technical characteristics of plant equipment. Manufacturers try to make the parameters as versatile as possible so that the wheels fit as large as possible car models.|
|Painting||There is a wide choice, the kit can be painted in several colors, polishing can be applied, you can choose the color of the wheels according to the car paint code, polishing or chrome plating of the wheels is possible. Each set is painted for a specific client and his car.||Batch of wheels reduces color options, paint options are much more modest, manufacturers try to guess the most requested colors. The paint quality is generally good, but due to the susceptibility of aluminum corrosion, the service life of the coating is significantly less than that of forged ones.|
|Purchase one of wheel||Possibly||Rarely|
|Balancing||Each wheel is checked.
10-15 grams per wheel is permitted
|Wheels from a batch are checked selectively. 40 grams is permitted.|
|Price||The production of forged wheels is a very resource-intensive, energy-intensive and labor-intensive process. This is why forged wheels are so expensive. And when carefully controlled, the wheels are of exceptional quality.||Party production, on average,
from 100 pcs. for one model with the same parameters and color significantly reduces the cost.
