Features of new IP black (PVD)
- Ion plating coating (PVD) with the highest blackness ever (Lab color space about L*35)
- Hard coating that can withstand bending tests and impact tests
- Incomparably superior wear resistance compared to wet plating
- High corrosion resistance that does not discolor or corrode even during long-term CASS tests and salt spray tests

Comparison of wear resistance performance with other black platings
| Evaluation method (PVD processing on SUS304 0.5mm thick plate) | New IP black | Black Sn-Ni plating | Black Ru plating | |
| Wear resistance performance | Reciprocating wear test Abrasive material: sand eraser Weight: 1.0Kg | No bare material exposed after 2,000 times | 250 times exposes the base material | 150 times exposes the bare material |
