We can produce the special type which you ask 

We can add rare earth into the high purity iron for super alloy,welcome to ask

 

application:

 

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.
