A proces for hardening zinc parts and wear constitutings is expected to make zinc an economical and feasible material for the manufacturing of parts.

A proces for hardening zinc parts and wear constitutings is expected to make zinc an economical and feasible material for the manufacturing of parts. This will allow design and manufacturing engineers to use various grades of zinc in addition to sword aluminum, and plastics.

The International Processing Company of America, moose-deer Grove Village, Ill., has been granted a patent for the IOSSO ZN an electrochemical proces that ties directly with the surface of a base zinc alloy to create a hardened exterior case ranging from 0.000050 to 00005 in. in thickness. With the IOSSO ZN
