#60. What is the five-letter name, derived from the latin for 'mild' , of the form of iron which is made malleable by the addition of a small amount of aluminum, in a process invented by a Swedish metallurgist. Help please.

Mitis Casting

A process, invented by P. Ostberg, for producing malleable iron castings by melting wrought iron, to which from 0.05 to 0.1 per cent of aluminium is added to lower the melting point, usually in a petroleum furnace, keeping the molten metal at the bubbling point until it becomes quiet, and then pouring the molten metal into a mold lined with a special mixture consisting essentially of molasses and ground burnt fire clay; also, a casting made by this process; -- called also wrought-iron casting.
