Where can I find out some iron loss coefficients of some classical material for motors?

The following is a table with some coefficients for some classical magnetic materials (for motors). Sometimes a range of value is given due to the fact that the same grade has been measured from different suppliers.

Material name	Hysteresis loss coefficient(in Ws/T²/m3)	Conductivity(in S/m)	Loss in excess coefficient (in W/(T/s)1.5/m3
350-65A	201-217	1.7 E6	0
400-65A	211-245	1.93E6	0
470-65A	264-301	1.93E6	0
530-65A	282-341	2.24E6	0
600-65A	335-376	2.24E6	0 – 7.9
