Hot Black Oxide

Hubbard-Hall’s Black-Magic® line of hot black-oxide products is frequently used to produce a true durable black oxide conversion coating on steel, stainless steel, and copper alloys. These essentially dimensionless coatings create very decorative, highly durable, black finishes that leave an absorbing oxide layer for oils and waxes that will provide for enhanced corrosion protection.

Black magic liquid products are caustic free, making it a safer chemical for your operators.  All chemical systems, such as hot black oxide have inherent risks and safety concerns, but knowledge and good housekeeping can help you maintain your process and safety.
