The invention aims to provide a casting material with a high thermal durability for use, in particular, in valve seat inserts. This is achieved by an alloy with the following composition: molybdenum: 20-40 % (by weight) - chrome: 5-20 % (by weight) - carbon: max. 0.3 % (by weight) - silicon: 0-10 % (by weight) - optionally 0-5 % (by weight) of the elements Ni, Mn, Co, V, Nb, Cu, Ti, Zr, whereby the sum of the optional components is a maximum 15 %, - residue: iron and conventional impurities.
