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

Charateristic

 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.

International standard

magnetic aging：keep 100 degree
for 100 hours or Condition is 790 degree after 2 hours, after cooling with the
furnace.

Appliance of trademark from B-B to B-C :

The raw material of all kinds precise alloy（super
alloy）,electric alloy,soft magnet,amorphous alloy
and permanent magnet such as NdFeB  etc.
