For the first time this technology has been developed and applied in Russia in the mid-80's on defense enterprise 'Wheels'. In this regard, we generally lucky. In Russia, the idle weight high-tech defense plants ready to produce anything, just would not completely fail. We are at a relatively lowest prices available wheel mass production, which in the West consider it appropriate to use for sports and racing cars (production technology there is somewhat different). Forged obtained by gradual deformation of the workpiece is processed and rendered entirely on the machines with a cutting tool. As a result, very many of the metal burns and goes to the chips – lost more than half of expendable material. For implementing these actions requires an expensive, complex and powerful equipment (force from the press is 20 tons). However, the benefits of full machining products is obvious: strength higher than steel wheels in 2,5 times and excess of 2 times the level required by gost plastic properties.
This is explained by the conservation of metal fibrillation. Therefore, under the influence of extreme dynamic loads are the wheel does not prick, and crushed, and no cracks does not occur – you can try to align. Also decreases mass compared to cast wheels of 15-20% (steel-stamped – by 40-55%), very high damping capacity, lack of foundry shells and harmful internal stresses, the maximum geometrical precision of execution and the absence of imbalances, high corrosion resistance for aluminum wheels (no protective coating). In this regard, maximum gain performance we get when used as a material of magnesium. Its density is 4,5 times less than steel and 1.5 times – than that of aluminum.

Forged magnesium wheels are called 'the wheels of the future. Their damping capacity of several tens of times higher and the weight to 35% lower than that of forged aluminum. The only drawback forged wheels – that is their price (although it is significantly lower than that of the cast of famous foreign counterparts). Yes also, perhaps, the fact that for some vehicles, they are perhaps 'too good': a serious accident, they will remain intact, but the suspension will come to a common denominator (though such a view of the problem is very debatable).
