We can produce the special type which you ask

application of trademark B-A:

a.make it in electric core.heel piece, gag bit in electric appliance device,telecommunication
b.Electric core of electric iron
c.Electromagnetic part of instruments and meters
d.Iron core and shell of direct-current dynamo
e.Electric part or magnetic part for car,tractor,lathe
f.Magnetic shielding apparatus

1 .good electromagnet character.Coercive force(Hc)low,high magnetic permeability. high saturation induction density Bs .stable magnet and no magnetic aging
2 high pure,electric pure iron,is full killed steel,refine,so the density is high,average,good,little gas, this is a reliable condition that customer simplify and cut down the anneal process of the parts.
3 cold drawn,hot roll,forge.Cold process,these is no problem such as lathe,drill,punch,bend,drawn.Hot process,such as forge,roll,there is little redsear sensibility,it is a good condition for doing in a large degree scope.
