we supply electric steel(electric magnet pure iron),melt pure iron, alloy steel, permanent magnet, silicon iron, amorphous strips, stainless powder etc. The chemical composition and physics characteristics, such as the coercive force is better than the International Standard. Normally we have 3000.00 metric tons special steel (pure iron and alloy steel,stainless powder) in our warehouse. Our fabrication plant is equipped with large cutting machine, shearing machine, sawing machine, punch, lathe, mill machine, annealing furnace, and rattle barrel to meet the different needs of users. We check and audit the quality according to the quality certificate strictly.

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,C≤0.004%, 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.
