Although the AC1 rims are a new design, in one important aspect they pay tribute to their heritage: they too will certainly become a design classic.\u003c\/p\u003e\u003cp\u003eWith the new AC1 rims, AC Schnitzer has reinterpreted the classic twin-spoke design. The result is a sporting hybrid look. In a sophisticated style, triangle tips taper towards the rim edge and widen towards the centre, separated by five trapezoids. These draw the eye directly to the unique classic element of the AC1 rim: the pentagonal hub cap with AC Schnitzer logo.\u003c\/p\u003e\u003cp\u003eDespite this multiplicity of styling elements, the design appears clean and masculine thanks to the very straight lines. The interplay of all these elements gives the AC1 wheel solidity and size. Especially in motion, the BiColor finish creates a strongly alternating effect.\u003c\/p\u003e\u003cp\u003e- weight reduction of approx. 30 % thanks to forging, compared with conventional cast wheels\u003c\/p\u003e\u003cp\u003e- perceptible reduction in unsprung mass and gyroscopic forces on the car, therefore\u003c\/p\u003e\u003cp\u003e- significantly improved driving dynamics\u003c\/p\u003e\u003cp\u003e- significantly improved acceleration and deceleration due to lower masses\u003c\/p\u003e\u003cp\u003e- improved cornering handling\u003c\/p\u003e\u003cp\u003e- machined ”Forged“ logo on the front\u003c\/p\u003e\u003cp\u003e- machined original AC Schnitzer logo\u003c\/p\u003e\u003cp\u003e- high quality clear lacquer protects the wheel against corrosion, therefore\u003c\/p\u003e\u003cp\u003e- long life\u003c\/p\u003e\u003cp\u003e- open 5-spoke design in BiColor giving a clear view to the brakes\u003c\/p\u003e\u003cp\u003e- evolutionary development step of the AC1 wheel\u003c\/p\u003e\u003cp\u003eMaterial\u003c\/p\u003e\u003cp\u003eAbout 97 percent of the melt consists of aluminium, but the remaining three percent of the wrought alloy also helps to influence the desired properties of the material for the ideal wheel. In addition to the main component aluminium, the alloy also contains one percent magnesium and one percent titanium each (which ensures finer grain size). The precise composition of the material alloy has a decisive influence on the subsequent properties of the wheel.\u003c\/p\u003e\u003cp\u003ePure Aluminium\u003c\/p\u003e\u003cp\u003eApproximately 97 percent of the alloy consists of pure aluminium. The remaining three percent of the wrought alloy is important for the properties of the material.\u003c\/p\u003e\u003cp\u003eChrome\u003c\/p\u003e\u003cp\u003eThe AlCr20 master alloy with the hard metal chromium improves recrystallisation resistance. Master alloy means a mixture of aluminium with other materials, in this case it is a maximum of 0.25% by weight of chromium, i.e. a very small amount.\u003c\/p\u003e\u003cp\u003eMagnesium\u003c\/p\u003e\u003cp\u003eTogether with pure silicium, magnesium leads to a higher strength of the total alloy. The maximum proportion of these materials is 1.2 and 1.3 percent by weight, respectively.\u003c\/p\u003e\u003cp\u003eTitanium\u003c\/p\u003e\u003cp\u003eThese glossy ingots are the master alloy AlTi5B1, which serves a finer grain structure of the total alloy. The proportion of the expensive raw material titanium is only 0.1 percent by weight.\u003c\/p\u003e\u003cp\u003eSilicium\u003c\/p\u003e\u003cp\u003eThese irregularly shaped lumps are only added to the alloy together with magnesium. This increases the strength. The silicium content is between 0.7 and 1.3 percent by weight.\u003c\/p\u003e\u003cp\u003eManganese\u003c\/p\u003e\u003cp\u003eThe addition of 0.4 to 1.0 % manganese makes the alloy tougher. Manganese has a positive effect on recrystallisation behaviour.\u003c\/p\u003e\u003cp\u003eManufacture\u003c\/p\u003e\u003cp\u003eForging - an elaborate process that must offer maximum safety. In many steps the wheel is prepared for its important task for a long car life. The process control guarantees excellent material properties, which are the reason for the low weight of our forged wheels. Even in critical driving situations, forged wheels offer the occupants optimum safety.\u003c\/p\u003e\u003cp\u003eStep 1: The nozzle\u003c\/p\u003e\u003cp\u003eA cast block more than 6 m long manufactured by OTTO FUCHS is the starting material from which a socket, which is precisely matched to the later wheel, is sawn off.\u003c\/p\u003e\u003cp\u003eStep 2: Pre-forging\u003c\/p\u003e\u003cp\u003eIn the first forging stage, the nozzle is pre-forged into a rotationally symmetrical blank with a force of 4,000 tons.\u003c\/p\u003e\u003cp\u003eStep 3: Design forging\u003c\/p\u003e\u003cp\u003eIn the second forming stage, the styling is pressed into the pre-forged blank under a 7,000 ton press, which gives the wheel its later appearance to a large extent.\u003c\/p\u003e\u003cp\u003eStep 4: Punching\u003c\/p\u003e\u003cp\u003eIn the last forging stage with 800 tons of pressing force, the later ventilation hole windows and the hub bore are punched out and the burr of excess material sheared off at the outer circumference.\u003c\/p\u003e\u003cp\u003eStep 5: Flow pressing\u003c\/p\u003e\u003cp\u003eThe outer edge of the blank is heated. The entire rim area, from outer to inner horn, is rolled out.\u003c\/p\u003e\u003cp\u003eStep 6: Finishing\u003c\/p\u003e\u003cp\u003eThe final step is finishing: turning, drilling and deburring. Painting rounds off the complex process.\u003c\/p\u003e\u003cp\u003eSource: Material and Production: Otto Fuchs KG\u003c\/p\u003e\u003cp\u003eSurface BiColor\u003c\/p\u003e\u003cp\u003eIn this process, the wheel is first primed and then completely painted. Now the surfaces, which are later to shine metallically bright, are turned off and then polished to a high gloss. Finally, a two-layer clear coat is applied, consisting of a polyester primer and the acrylic clear coat.\u003c\/p\u003e\u003cp\u003eTest Procedures \/ Safety\u003c\/p\u003e\u003cp\u003eAfter their design, the first sample rims are manufactured under real production conditions. These must undergo a multitude of tests. Among other things, the strength is tested. The \"rim life\" is simulated in the bending circumferential test. Every AC Schnitzer rim must withstand this intact in order to be allowed to be produced and sold at all.\u003c\/p\u003e\u003cp\u003eThis is followed by vehicle-specific tests, including test installations with check of unobstructed movement and driving tests on public roads and on race tracks. Only after these procedures our rims receive their homologation, i.e. the approval to be used in road traffic.\u003c\/p\u003e\u003cp\u003eWheels are safety-relevant components. Therefore, they are checked and tested with the greatest care.
