application of
trademark B-A:
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??highsaturation
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.**4%?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?
