A method for making a light alloy foundry part that includes at least one piping supported by a wall of the part. The method includes making the piping, making a mold reproducing a shape of the part without the piping, positioning the piping in the mold, and casting a metal for making the part. At least a portion of the piping is subjected, prior to the installation thereof in the mold, to a surface-processing to generate a thermal barrier between the portion of the piping and the casting metal, the mold including at least one hollow location around the piping for making a bridge for supporting the piping and extending from the wall of the foundry part.

A process for manufacturing a process for manufacturing a part made of a magnesium alloy is disclosed. The process includes a step of forging a block of the alloy followed by a heat treatment. The alloy is a casting alloy based on 85% magnesium, and containing, by weight: The forging is carried out at a temperature above 400&#xb0; C. In particular the temperature is set between 420 and 430&#xb0; C. and the forging step comprises a plastic deformation carried out at a slow rate. The process allows one to produce parts such as elements of casing for aeronautical machines, operating at a temperature of around 200&#xb0; C. and having good aging properties.
