2021 The Latest Antique Retro Copper-coated Stainless Steel Sheet&Trims


Stainless steel antique copper is a more popular decorative material at present.

Which is mainly obtained by the old and retro treatment of stainless steel through special processing technology. 

Stainless steel antique copper can bring a retro, heavy, and simple atmosphere 

Which is very high-grade and rich in culture. 

Therefore, it is widely used in copper doors, copper decorations, bronze carvings, retro furniture copper accessories. 

Four treasures of the study, antiques, and copper Handicrafts, incense burners, copper handles, reliefs, showcases.

Curtain walls, sculptures and other fields have been well received and loved by customers. 

The use of stainless steel antique copper has many advantages: 

The production and processing cost of stainless steel antique copper is much lower than that of copper. 

So the processed products have a greater price competitive advantage, and the same effect can be achieved with less cost; copper is harder Low. 

It is difficult to use in a large area, and the hardness of stainless steel antique copper is much higher; the chemical properties of copper are relatively more active than stainless steel. 

Stainless steel antique copper is much better than copper in corrosion resistance, wear resistance, waterproof and rust resistance, and has a longer service life.



The color of stainless steel copper plating: bronze, bronze, red copper, brass, blackened bronze


There are generally two processes for copper plating on stainless steel: the first is vacuum plating. 

Then plating is a process that uses electrolysis to attach a metal film to the surface of a metal or other material. 

It can prevent corrosion, improve wear resistance, electrical conductivity, reflectivity and enhance aesthetics.

The second type is water plating, which is the most used at present, stainless steel water plating: 

It does not rely on external power supply in the aqueous solution, and relies on the reducing agent in the plating solution to perform chemical reduction reactions. 

So that metal ions are continuously reduced on the autocatalytic surface. 

Process method for forming metal plating. Its processing flow is first to dewax and degrease the workpiece to be plated. 

After activation, the alkaline copper is electroplated first. The electroplating time is about 10 minutes. 

After being discharged from the tank, it is washed, neutralized and activated, and then copper bright electroplating is performed. 

The plating time is more than 20 minutes. When the plating layer is thick enough, it is washed, activated, and electroplated with nickel and black directly. 

The plating time should be uniform black on the surface of the workpiece.

Then washed with water, dried, and processed. Copper bright electroplating workpieces can also be blackened after washing. 

Generally, they are soaked in 5% potassium sulfide aqueous solution and turned repeatedly. 

When the surface of the workpiece appears black or brown, remove the workpiece, wash it, dry it, and wait. 

Processing. Then, the workpiece that has been plated with black nickel and gun color or blackened is polished with a nylon wheel. 

According to the requirements of the patina, the degree of polishing is grasped. 

When the workpiece reaches the desired effect, the electroplating varnish is sprayed, that is.

We say The fingerprint-free processing and then drying and packaging are enough.
