TRANSCRIPT
TYPICAL DC MAGNETIC PROPERTIES*
DESCRIPT IONCarpenter VIM VAR Core Iron is a low carbon magnetic iron produced using vacuum induction melting plus vacuum arc remeltingpractices. Other elements commonly found in low carbon irons are held as low as possible to ensure good DC magnetic properties. This double melting technique controls the distribution of nonmetallic inclusions to a minimum length and frequency so thatthin wall sections will not contain leaks due to internal discontinuities.
APPLICATIONSCarpenter VIM VAR Core Iron is often used in the manufacture of soft magnetic components where vacuum integrity is neededsuch as in power tubes and microwave devices. In addition, relays, solenoids, and magnetic pole pieces for scientific instru-ments may be made utilizing the qualities of VIM VAR Core Iron. AKA: Carpenter Consumet Core Iron1.
