<p>The method for producing a motor vehicle component such as a running-gear component, comprises providing a mineral core body, heating the core body, casting the core body with a light metal casting, producing a blank and processing the blank and shaping the motor vehicle component. T he core body is heated up to a temperature in which gas present in the core body is expelled to the predominant part. The heating is carried out at 300-700[deg] C. The core body is heated at a temperature, which corresponds with a deviation of +- 100[deg] C of the temperature of the light metal casting.

T he core body is heated up to a temperature in which gas present in the core body is expelled to the predominant part. The heating is carried out at 300-700[deg] C. The core body is heated at a temperature, which corresponds with a deviation of +- 100[deg] C of the temperature of the light metal casting, which has a cast around the core body. The core body is provided before or after the heating with a sealing or coating. Aluminum-iron magnesium silicate or aluminum-iron-magnesium-silicate is used the core body. Aluminum and/or an aluminum alloy or magnesium and/or a magnesium alloy is used as the light metal casting. The density and/or the strength of the core body is adjusted during the forging process. In the forging technique, the processing of the blank is carried out at 400-600[deg] C.</p> |
