With the increase in time, many advantages of aluminum alloy wheels have been recognized and accepted by more and more people, and the amount of loading has also increased. There is a relatively cheap forged aluminum alloy hub in the near-card reaction market. What is the difference between this type of forged aluminum alloy hub and the forged aluminum alloy hub?
â— Forged hub technology is relatively simple and suitable for low production costs
Low-pressure forging is a more fundamental method of producing aluminum wheels. It is also more economical, and more common are low-pressure forging and high-pressure die casting. Low-pressure forging is to mold and harden the molten metal in a mold, and the cooled blank is finally processed through a lathe's precision machining and polishing process.
High-pressure forging is the leading forging method. Suction from high vacuum is used to suck the melted metal into the mold. This will help to maintain the constant temperature text to eliminate impurities. The casting has no pores and the density is uniform. The strength is higher than the low pressure forging. . Forging technology process is relatively simple and suitable for mass production to reduce costs.
â— Forged wheel hub technology is expensive but its function is very good
Forging is the current leading method for producing aluminum wheels. Forging aluminum wheels is a certain pressure to put an aluminum ingot in a hot state, using a large forging press to repeatedly forge into a wheel blank. After forging, the blank is spin-treated. The effect of this process is to stretch the width of the rim to reach the corresponding specification. After the spinning technology, the rear hub is basically formed, and then the lathe can be finished. After grinding and painting, the aluminum alloy wheels of the products can be obtained.
Because the forging technology is cluttered and the forging equipment is expensive, (the cost of a large forging press will cost tens of millions of yuan), so the cost of the forged wheels is relatively high.
â— Metallographic analysis forged wheels function very well
We can see that the cut surface of the forged hub below is very lubricated, and the metal grains are placed tightly without roughness, while the forged aluminum wheel metal grains are loosely scattered, and the larger cross section of the metal particles has a strong sense of roughness.
Investigation under the microscope revealed that the metal molecules on the right side of the forged hub are loosened and loose particles are larger, and the metal molecules on the left side of the forged aluminum alloy hub are placed very tightly. The tighter the placement of metal molecules, the higher the wheel's resistance, and the better the impact resistance, strength, and bearing properties.
â— The appearance of indistinguishable components is different
Forged wheels and forged wheels are simply indistinguishable from each other in appearance. They differ only in terms of their metal characteristics. Forged wheel hubs are more resistant to impact, strength, and bearing capacity than forged wheels. Both have not much heat dissipation. s difference. But forged wheels are generally 20% heavier than forged wheels.
â— Postscript
Although forging aluminum alloy wheels and forged aluminum alloy wheels are slightly different, the function of the forged wheel alloy wheels produced with newer technologies is already very close to the forged wheels. Cardmates can choose their own vehicle conditions according to their own conditions. The aluminum alloy wheels, but beware of some unscrupulous merchants using forged wheels posing as forged wheels for sale.
