Company Description

we supply electric steel, electric
magnetic iron, ultra low carbon magnetic iron bar,soft magnetic iron bar
SUYB-1, Pure iron(SAE AMS 7707C Iron,ingot iron,high purity iron billet,soft
iron ,ASTM A848 alloy 1, The chemical composition and physics characteristics,
such as the coercive force is better than the International Standard. 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.

electric appliance device,telecommunication



b.Electric core of electric iron



c.Electromagnetic part of instruments and

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, 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
.
