黒いネジというと、どうやってネジの表面を黒くするのか、黒いネジの材質は何なのか、気になるお客様も多いです。 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.通常、ステンレス鋼の黒色化は、高温黒化、黒色電気泳動、QPQ黒化、真空黒色電気めっきなどの表面処理によって行われます。コストは鉄素材に比べて比較的高価です。

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!
