Just to stick my nose in. Several mentions of magnetic properties were
made. If you were thinking of properties in the low field region such as
earth field measurements, Iíve only seen those properties in
manufacturerís spec sheets for metals/ferrites suitable for low fields.
Allied Signal for Metglas for instance:
and Magnetic Metals for tranformer laminations and Permalloy:
Standard steels/irons are pretty much unsuitable at low levels as their
permeability drops pretty low around zero magnetization. Thatís why
those applications are pretty much dominated by Metglas and Permalloy
materials. For higher levels such as power transformers, you need to
check with manufactures of EI laminations, such as Magnetic Metals
above, who make the oriented silicon steels used in transformers. Their
spec sheets will show saturation curves and energy loss curves.
The ASTM books should be great for structural and chemical properties.
