application of trademark B-A:
a.make it in electric core.heel piece, gag bit inelectric appliance device,telecommunication
b.Electric core of electric iron
c.Electromagnetic part of instruments andmeters
d.Iron core and shell of direct-currentdynamo
e.Electric part or magnetic part forcar,tractor,lathe
f.Magnetic shielding apparatus
Charateristic
1 .goodelectromagnet character.Coercive force(Hc)low,high magneticpermeability. high saturation induction density Bs .stable magnet and no magnetic aging
2 high pure,electric pure iron,is full killedsteel,refine,so the density is high,average,good,little gas, this is a reliablecondition 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 aslathe,drill,punch,bend,drawn.Hotprocess,such as forge,roll,there is little redsear sensibility,it is a goodcondition for doing in a large degree scope.
