The Different Types of Metal Blackening Solutions


Metal blacking is one of the many ways which we can quickly and effectively change the colour of metal. Typically used on steel and iron, blackening will provide a high quality and protective black finish, leaving you with a finished metal that it far more visually appealing.

If you would like to know more about this process, keep reading and we will tell you how it could benefit you.

What is Metal Blackening?

The process involves placing a metal object into a chemical solution, at a specific temperature for a set amount of time. The duration required is usually no more than 5 minutes as long as the correct temperature window is maintained.

At this point, the metal object is removed and left to dry where it will then be lightly abraded with a rough material to remove any excess solution and to make sure any creases have been properly filled.

What you will be left with is an aesthetically pleasing piece of metal, of the same quality of the base material, but featuring a few additional benefits such as corrosion resistance.

Why Use It?

The benefits to this process are numerous. Metal in its raw state is usually susceptible to rust as well as other undesirable effects. Furthermore, depending on use, some metals need to be heat treated or painted so they can be more effective in high risk environments such as within high rise buildings which are at greater risk of the spread of fire.

Other benefits include:

  • The preservation of tight manufacturing tolerances where other colour methods might change the dimensions of a metal.
  • A corrosion resistant surface that can absorb wax and oil to give protection from rust.
  • A black finish can enhance the aesthetic appeal of a variety of metal objects and equipment, increasing sales.
  • Blacking can provide an increase in safety by removing the ability of metal to reflect light, reducing glare and worker fatigue.

Solution Strength

Of course, not all blackening requirements are the same. For this reason, a variety of solution strengths are available which can be used to control the extent to which any metal object reacts to the blacking process.

Some of these solution types are water and oil based, whereas some contain conditioning agents and degreasing properties. The strength and type of the solution can be controlled to the extent that there will likely be a treatment suitable for any type of environment.

These solutions are regularly tested to ensure that they meet all of the required safety guidelines and legislation, leaving you safe in the knowledge that they are in fact safe.
