Talk:Supermalloy

Magnetically soft material? I think it is a hard material. --Chrumps 10:12, 21 October 2007 (UTC)[reply]

It may be mechanically hard, I dunno, but it's used in transformer cores and called "Permalloy", i.e., magnetically permeable, so it must be magnetically soft. I think a distinction is possible. Ferrite ceramics are all brittle-hard, but are also magnetically soft for cores, or magnetically hard (high coercivity) for ceramic permanent magnets. --jimswen (talk) 09:01, 8 August 2009 (UTC)[reply]

6nOhm.cm2/cm (6 nano-Ohm.cm) can't be correct, must be a mistake. (Ohm.cm2/cm is the same as Ohm.cm. I'm not trying to contest the units.) The most conductive metals, Copper and Silver, are 1.7 micro-Ohm.cm. 6 micro-Ohm.cm for this alloy is possible but sounds low. Pure Iron is about 10 micro-Ohm.cm, then with Ni & Mo to mess up the crystal lattice, the resistivity should become higher than 10, perhaps 60, micro-Ohm.cm. --jimswen (talk) 09:14, 8 August 2009 (UTC)[reply]

Right you are, I changed it. You could even do the same in future. -Oreo Priest ^talk 16:57, 8 August 2009 (UTC)[reply]

extremely high magnetic permeability (approximately 800000 N/A2)

This cannot be true. The unit indicates an absolute permeability, but this number is way too high. I suspect, relative permeability is meant, which would mean the unit's got to go (relative permeability is unitless). I have no datasheet to confirm, though.
