Maximum strengths coupled with very high ductility render forged aluminum the ideal material for safety-relevant parts which also need to be light – a perfect combination for unsprung masses on the front axle. Hirschvogel develops and forges weight-optimized steering knuckles, both in Germany and in China. Upon customer request, the parts are machined ready for assembly on state-of-the-art machining centers. To verify the properties in operation as well as to ensure consistently high serial quality, Hirschvogel carries out quasistatic and dynamic one-dimensional fatigue tests.
