Electroplated copper is a thin-film material that is coated with a layer of copper on the surface of other materials, usually by electrolytic deposition. Pure copper is a material made entirely of copper, the higher the purity, the better the electrical properties.

I. Definition of Electroplated Copper and Pure Copper

Electroplated copper is a thin-film material that is coated with a layer of copper on the surface of other materials, usually by electrolytic deposition. Pure copper is a material made entirely of copper, the higher the purity, the better the electrical properties.

Second, the nature of copper plating and pure copper differences

1. Different hardness

Pure copper is softer than electroplated copper, while electroplated copper is harder. Therefore, in some applications that require a harder surface material, such as electronic circuit boards, copper plating is more advantageous.

2. Different conductivity

Copper is a good conductor, but the conductivity of copper plating will be slightly less than pure copper, this is because the dense structure of the copper plating surface will reduce the conductivity.

3. Different corrosion resistance

Electroplated copper relative to pure copper has better corrosion resistance, this is because the electroplated copper surface will form a layer of protective oxide layer, can play a role in corrosion. Pure copper is susceptible to the effects of oxidation, turning dark red.

Third, the application of copper plating and pure copper scene

1. Electronic circuit board manufacturing

Electronic circuit boards usually use electroplated copper to protect the lines and electrical connections, thus providing good conductive properties and corrosion resistance.

2.Furniture Decoration

Furniture made of pure copper is more elegant in appearance, while electroplated copper furniture is more robust. The choice can be made according to the actual needs.

3. Kitchen appliances

Since copper can inhibit the growth of many bacteria, pure copper is widely used in the manufacture of kitchen utensils, which not only adds to the aesthetics, but also contributes to hygiene and health
