自1937年以来, Hubbard-Hall has been setting the pace for the metal blackening industry. Using our chemistry, you are able to create a wide range of colors through chemical reactions. 一磅换一磅， 黑魔法® blackens 50% more than other black oxide processes. A true conversion coating, that yields an attractive, long-lasting finish that won’t peel, 片状或片状.
The development of 黑魔法®, 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.
- Lower replenishment costs by 20% with chemistry that is less viscous and has a lower concentration of salt
- Lower operating temperature (280◦ – 285◦ F) saves you up to 15% in energy costs
- Lower drag out by 30% with a thinner, wetter chemistry
