Hubbard-Hall’s Black Magic is a high-performance alkaline nitrate black oxidizing solution, with a boiling point of 285°F and a salt concentration of approximately 6 lbs. per gallon. It creates a durable black iron oxide coating that enhances appearance, corrosion resistance, and lubricity. Key components include sodium hydroxide, sodium nitrate, sodium nitrite, and rectifiers, which work together to produce a uniform finish and handle contaminants. The rectifier plays a crucial role in managing impurities and maintaining solution quality.
- Achieves a durable, scratch-resistant black finish with moderate corrosion resistance.
- Reduces operating costs by minimizing dimensional changes and ensuring a uniform finish.
- Extends bath life and performance through effective rectification and maintenance practices.
