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.
