Choose Cold Blackening for Durability and Appearance


What does it mean to blacken steel?

To understand this process completely, it’s necessary to dig back into history a bit to what was referred to as “bluing” in years past. This traditional method of protecting against rust also gave guns their recognisable blue/black appearance. This can be distinguished from more modern black coatings, also called metal blacking or blackening.

This finishing operation changes the chemical composition of metal surfaces and creates a barrier that helps the metal resist rust. It’s considered cost-efficient compared to plating or painting and is preferred in many cases because it fills small spaces in the metal’s surface for better protection. Today, there are companies that specialise in this process and related metal protection techniques.

Room Temperature

Cold blackening steel is one of the key advancements in metal protection. While companies and skilled individuals have been using a similar process for many years, the major change comes with the word “cold.” Today, it’s possible to get the benefits of this method with a process conducted at room temperature. This easy-to-use immersion process does not alter the dimensions of the component being treated, which is essential to manufacturers of precision-engineered products.

Those who produce components in the tooling industry and the machine manufacturing industry appreciate that this process results in no dimensional change so tight tolerances can be maintained. In most cases, plating and painting cannot deliver these results. In addition, cold blackening produces a black surface that absorbs oil, wax, and rust-preventative sealants for additional protection from corrosion and moisture.

Those who operate machinery or use other blackened components also appreciate the glare-reduction capabilities of the process. While these attributes are essential, this blackening process also adds a durable black finish that enhances the appearance and value of any manufactured product or component. All these benefits are important to tooling manufacturers, independent engineers, and others who are interested in the highest-quality products and outstanding value for their investment.

Simple, Fast

If you’re in this category of potential customers, you’ll also appreciate the fact that the solutions used in this unique process are designed to be “topped up” and not replaced. It’s also a time-efficient method because the solution is ready for use any time. There’s no need to prepare because tank lids can be removed and the components blackened right away. The solution covers at a high per-litre rate so the cost per unit or component is much lower than with conventional blacking methods.

You’ll also benefit from the decades of experience when you work with the leading provider of cold blackening. This process is proving to be much safer than hot blacking and, as mentioned, it’s more time-efficient and cost-efficient.
