The article provides the results of investigations regarding an effect of AZ91 magnesium alloy on iron present in the walls of a crucible operating in the furnace of a die casting machine. It is commonly assumed that liquid magnesium remains neutral in respect of iron, and therefore steel crucibles are believed to be the best solution in the technology of magnesium casting. However, careless handling of magnesium alloy, badly adjusted temperature of holding, and the use of protective gas may result in a dangerously quick thinning of the crucible walls, and hence in their shorter life and greater risk of magnesium penetrations.
