We can produce the special type which you 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.

Applications
HIGH PURITY IRON is used largely as the basic material for (re-)melting of low-carbon,
stainless and acid-resistant steels, materials with a high nickel content, magnetic alloys as well as stainless and heat resistant steel castings in induction and vacuum furnaces.
HIGH PURITY IRON is also used in many applications of aviation construction, nuclear
technology, the production of magnets (pole cores, yokes and armatures), in automotive construction, as magnetic shielding, as welding rods and fuse wire, as gasket in the chemical and petrochemical industry, power station construction, as anti-corrosion anode and as galvanizing tank including equipment.

The purer a metal is, the better it conducts electrical current. Materials of the greatest
possible purity are therefore required for current-carrying components. Even fractions of a percent of C, Si, P, S, Mn and Cu, which are found in normal types of steel, impact the electrical conductivity, which corresponds to the reciprocal value of the specific resistance.
