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(ELEMENT) not more than 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.
