Magnetic powder DXF-5 series

Product overview
Magnetic Powder for Recording is a barium ferrite (BaFe12O19) based magnetic powder formulated for the preparation of magnetic cards and magnetic stripe products. It provides plate-like ferrite particles with narrow particle size distribution and stable temperature performance for reliable magnetic recording in stripe and ticket applications.

Applications

• Magnetic stripe credit cards
• Railroad tickets and season tickets
• Highway passes
• Telephone cards and prepaid railway cards
