Type mm :
Medium plate and steel billet 8-250 ,plate coil 12-25 ,straight round steel dia6.5-dia300 ,round steel coil,cold drawn plate coil 0.5-2.5etc.
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 densityBs .stable magnet and no magnetic aging

2high 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.
3cold 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.
