[origin: DE19620923C1] The invention concerns a bottom-half mould for a device for producing concrete roofing tiles. According to the invention, in order to produce a bottom-half mould which can be cleaned under more gentle conditions, the front face of the bottom-half mould, at least in the surface-forming region, consists predominantly of magnesium. To that end, the surface-forming region of the bottom-half mould can consist of a magnesium alloy. The magnesium alloy should contain approximately between 7 and 9.5 % aluminium, approximately between 0.3 and 1 % zinc, and approximately between 0.1 and 0.3 % manganese.
