摘要

Cams which meet all strength requirements and can be shrunk on a shaft can be made in a simple manner by sintering from a nickel- and copper-free mixture which comprises iron powder and contains 0.3 to 1.0 weight percent carbon and molybdenum and/or tungsten in such amounts that the sum of the molybdenums content and the tungsten content multiplied with the ratio of the atomic weight of molybdenum to the atomic weight of tungsten lies between 0.5 and 3 weight percent.
