num, which is so clearly a factor of great importance in the design of such
furnaces, is the low emissivity of the different aluminum alloys. This value varies
considerably with the condition of the surface, from about 0.050 for bright
aluminum, ...

The Wheeling process takes advantage of the fact that small percentages of
aluminum, when thoroughly mixed with the zinc metal in the coating bath, will
suppress the brittle iron-zinc alloy layers which normally would be formed. The
reason ...
