Steve Sells Posted October 21, 2011 Share Posted October 21, 2011 Also the additional silicon increases conductivity, Used in many electrical applications, including buss bars as well as transformer cores. Quote Link to comment Share on other sites More sharing options...
thingmaker3 Posted October 24, 2011 Share Posted October 24, 2011 Transformer lamination composition is all over the map. Some has silicon, some does not. Some are mostly nickel, others less so.http://www.magmet.co...n/materials.phpPage three of this pdf But yes, silicons steel was indeed widely used in the past. Also the additional silicon increases conductivity, I had not heard of this before. Steve, can you steer me toward some additional reading, I'd like to know more about this effect of silicon in steel. Quote Link to comment Share on other sites More sharing options...

ThomasPowers Posted October 24, 2011 Share Posted October 24, 2011 Steve I read both of those sites and neither one says it increases conductivity. In fact the second one says "the added volume resistivity helps to reduce eddy current losses in the core" Increasing resistivity is the opposite of increasing conductivity. As I understood it the Si was for the magnetic effects trying to get minimal hysteresis with fluctuating fields. I'll have to dig out "Alloying elements in Steel" and see what it says.

Steve Sells Posted October 24, 2011 Share Posted October 24, 2011 I may also have posted the wrong link, thanks for pointing that out, I will look around I have had a few Electrical buss bars at almost 2% silicon, I just gotta dig....
