What material are black screws made of？

When it comes to black screws, many customers are curious about how to make the surface of the screws black and what specific material the black screws are made of. Let's follow the steps of Anzhikou Screw Manufacturer to take a look:

In fact, there are generally two common materials for making the surface of screws black. One is iron material. Since iron screws have poor anti-rust and corrosion resistance, surface treatment is needed to enhance their anti-rust and corrosion resistance. The other is stainless steel material. Usually, stainless steel is made black through surface treatments such as high-temperature blackening, black electrophoresis, QPQ blackening, or vacuum black electroplating, etc. The cost is relatively higher compared to iron material.

The above two materials are the commonly used by customers for black electroplating treatment. Of course, we also can make brass, aluminum and titanium in black!
