Alloy Technic B9 wheels are specific to the BMW marque.
They are 8000 ton Forged using 6000 series and strengthened with T6 treatment.

Julius, these wheels are made using Rotary forging. is this a typo?

I am VP of the forging company who makes the Alloy Technic brand.
The wheels are indeed rotary forged using a 10,000 ton rotary forging machine.
The press, built by our company and in service since 1996, uses two gigantic rotating discs canted at 5 degrees from horizontal.
This concentrates the 10,000 tons of force in a smaller area, “working” or “forging” the metal to a much greater degree than conventional presses.
The forgings are then flow-formed on the largest CNC spinning machine in North America, further “working” the material under millions of pounds of force.
The result are wheels with mechanical properties some 15 to 30 percent higher than conventional 6061 T6 forgings.
This technology, combined with our exotic heat-treat processes, is what makes our wheels so strong and lightweight.
More than 50% of our forgings are used for military and aerospace applications and 75% of European tuners use our forgings exclusively for their forged product.
Over the past decade, we have produced more than 1 million forged wheels, without a single operational failure or failure in service.
This includes all the forged wheels for the Dodge Viper program, the forged wheels for the Chevrolet Corvette, and all the forged wheels bearing the Roush brand.
Any suggestion that rotary forgings are somehow inferior to conventional forgings is simply an uninformed opinion with no basis in science, metallurgy or fact.
I hope this clears up any confusion.
