notes 1. TAD is the malleable iron material of the amount of least carbon which gas gave.
2.1LSSP of notes is a reference value except Si.

[Feature]
TAD • Saturation induetion is high and Permeability is good, it is mostly used on the parts for direct-current magnetism circuits.
• Workability is good.
1 LSSP • Maxmum permeability is high and the magnetic property in an inside low magnetic field is excellent.
