Company description:

we supply Pure iron, High Purity Iron Billet,soft iron, iron remelt ingot,electric steel(iron),electric magnetic iron,ultra low carbon magnetic iron,soft magnetic iron bar SUYB-1, SAE AMS 7707C Iron,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. Trademark B-A Chemical composition(%,max) C 0.003 Si 0.01 Mn 0.20 P 0.012 S 0.006 Al 0.15-0.50 Cr 0.02 Ni 0.01 Cu 0.02 Trademark B-AA Chemical composition(%,max) C 0.002 Si 0.006 Mn 0.12 P 0.007 S 0.001 Al 0.15-0.50 Cr 0.02 Ni 0.01 Cu 0.005 Trademark B-B Chemical composition(%,max) C 0.003 Si 0.01 Mn 0.13 P 0.009 S 0.006 Al 0.03 Cr 0.01 Ni 0.01 Cu 0.02 Trademark B-C Chemical composition(%,max) C 0.002 Si 0.01 Mn 0.03 P 0.006 S 0.005 Al 0.01 Cr 0.01 Ni 0.01 Cu 0.01 Type(mm): Medium plate and steel billet(8-250),plate coil(12-25),straight round steel(dia6.5-dia300),round steel coil,cold drawn plate coil(0.5-2.5) etc. We can produce the special type which you ask 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,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. International standard trademark coercive force Hc A/m(oe) not more than coercive force aging Hc A/m(oe) not more than Max.magnetic conductivity H/m(Gs/Oe)* not less than magnetic strength T(Gs) not less than B-A 48.0(0.6) 4.8(0.06) 11.3 (9000) B200 B300 B500 B1000 B2500 B5000 B10000 1.20 (12000) 1.30 (13000) 1.40 (14000) 1.50 (15000)　 1.62 (16200) 1.71 (17100) 　1.80 (18000) magnetic aging:keep 100 degree for 100 hours or Condition is 790 degree after 2 hours, after cooling with the furnace. Appliance of trademark(from B-B to B-C): The raw material of all kinds precise alloy,electric alloy,soft magnet,amorphous alloy and permanent magnet(such as NdFeB) etc.
