Vim Var Core Iron Soft Magnetic Alloy

Carpenter VIM VAR Core Iron (aka Carpenter Consumet Core Iron¹) is a low carbon magnetic iron produced using vacuum induction melting plus vacuum arc re-melting practices. 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 that thin wall sections will not contain leaks due to internal discontinuities.
