Infusing Innovation. Reducing Cost.

The development of Black-Magic®, the first single-bath blackening process for steel, initiated a string of innovations. One of the biggest innovations when using Black-Magic Infusion is your ability to reduce cost.

 

20%

Lower replenishment costs by 20% with chemistry that is less viscous with a lower concentration of salt

15%

Lower operating temperature (280◦ – 285◦ F) saves you up to 15% in energy costs

30%

Lower drag out by 30% with a thinner, wetter chemistry

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 enhanced corrosion protection.

Black magic liquid products are caustic-free, making them 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.

Room Temperature Black Oxide

Black Magic room temperature blackens 50% more than other black oxide processes. This chemistry is the best money-saving, in-plant process for blackening. It’s applied at room temperature and saves you energy and trouble. It finishes your steel and iron products with a uniform, black surface that is smut-free and safe to apply.  No heated solutions, no high capital outlay, it’s your online process for maximum productivity and savings.

Antiquing Solutions

The Mi-Tique® antiquing and metal coloring products are used to give an aged appearance to decorative hardware, bath fixtures, some jewelry, and other decorative accessories. Through chemical conversion, a variety of metals including copper, brass, bronze, nickel, silver, and pewter can be oxidized to produce black, brown, and green patinas. By varying time and concentration, users can achieve multiple shades of color from light brown to black. Tumbling, rubbing, or relieving the surface to highlight lettering or create contrast in designs, can create additional effects. See Hubbard-Hall’s Mi-Tique® 1792 antiquing solution in action.
