[Amps] Microsil-Hipersil to M6 comparison

[Will Matney]

I did some research today for any interested in the iron loss for Microsil (Hipersil) at 15 kilogauss compared to M6 material used in EI lams. The Microsil is on a chart at magnetic metals so you'll have to reference it there or take my word for it. The link to the chart is below and is the bottom two charts for 12 mil thick material. The information for M6 is at tempel steel and is reprinted below or a link to it. Hope this helps for the ones who might be interested.

M6 in 29 gauge (14 mils);
With a 75%-25% grain (worse case);
29 gauge is 0.99 watts per pound
26 gauge (18.5 mils) is 1.12 watts per pound
(Both guaranteed)

For Microsil, Hipersil, Silectron Z, and Oreintal T-S

The chart for 12 mils as close as I can see at 15 kilogauss is around 1.2 to 1.3 watts per pound guaranteed from Magnetic Metals. see the bottom two watts per pound loss curves. The measurement is at the top of the line for 15 kilogauss at 60 Hz.

Cross References

Microsil (Silicon Grain Oriented Steel) 
Other names: Silectron Z, Oreintal T-S, Hipersil

1,2 mil in  C, E;   
At high frequencies where eddy current loss is significant, pulse transformers, chokes.

4 mil in C, E;
Up to 16 KG, at 400 Hz; transformers, filter chokes, reactors, amplifiers, pulse transformers.

7 mil in C, E;
Up to 18.0 KG, the performance of 7 mil material at 400 Hz will be equal to or better than the performance of 4 mil class MH or MZ cores.

9 mil in C, E;
Up to 18.5 KG, at 60 Hz. Applications are the same as A and S materials but can be used in smaller envelope requirements.

12 mil in C, E;
Up to 18.5 KG at 60 Hz for transformers, filter chokes, reactors, magnetic amplifiers (exciting current increases rapidly above 15 KG).

========================================

Supermendur 

4 mil in C, E;
At 400 Hz to 800 Hz, highest flux density; power transformer, filter chokes.

========================================

Superperm 49 (50% NiFe)
Other names: High Permeability "49", 48-Ni5, 4750

1, 2, 4 mil in C, E;
At high frequencies or in pulse transformers requiring higher pulse permeability and lower cores loss than Microsil.

========================================

Superperm 80 (80% NiFe)
Other names: 4-79 Permalloy, Hymu "80", Mu-Metal, Hypernom

1, 2, 4 mil in C, E;
At high frequencies, low noise, power and pulse transformers requiring low remanence, highest permeability and lowest loss.


Hope this helps for the ones wanting to make a determination in what to buy. Any questions, please feel free to ask.

Best,
