subject: Making a spray formed rapid tooling [print this page] Metals usable for this purpose include metals such as zinc and high temperature high strength carbon steel. These include certain rapid tooling steels such as plain carbon steel with (0.8% carbon by weight) as well as maraging steels. Maraging steels are difficult to machine and are seldom used for tooling, but can be readily spray formed to produce a desirable microstructure.
