Nickel coated copper powder is a kind of mixed powder, which is composed of two metals, nickel and copper. It has excellent electrical conductivity and electromagnetic shielding properties, and is widely used in conductive rubber, conductive coating and other fields. The following are four aspects of nickel-coated copper powder:

Product introduction

Nickel-coated copper powder is a kind of mixed powder with nickel as the core and a layer of copper coated on the surface. Its particle size is generally less than 100 microns, and the shape is spherical or irregular. The preparation method of nickel-coated copper powder usually includes three steps: preparation of copper-coated nickel alloy, preparation of copper alloy micropowder, preparation of nickel-coated copper powder. It is necessary to pay attention to safety issues in the preparation process to prevent toxic and harmful gases from chemical reactions.

Product characteristics

Nickel coated copper powder has the following advantages:

1. Good electrical conductivity: nickel and copper are good conductors, so nickel-coated copper powder has good electrical conductivity and can be used to make conductive rubber, conductive paint and other products.

2. Excellent electromagnetic shielding performance: Because nickel-coated copper powder has good absorption and reflection of electromagnetic waves, it can be used to make electromagnetic shielding materials.

3. Corrosion resistance: nickel and copper have good corrosion resistance, so nickel-coated copper powder is not easy to rust in a humid environment.

4. Environmental protection and non-toxic: nickel coated copper powder non-toxic and tasteless, in line with environmental requirements.

Application fields

Nickel-coated copper powder is widely used in the following fields:

1. Conductive rubber: nickel-coated copper powder can be used to make conductive rubber, which is used to manufacture shells and buttons of electronic products.

2. Conductive coating: nickel-coated copper powder can be used to make conductive coating, coated on the surface of various materials, to achieve conductive and electromagnetic shielding effect.

3. Electromagnetic wave shielding materials: nickel-coated copper powder can be used to make electromagnetic wave shielding materials to prevent electromagnetic wave interference and radiation.

4. Composite materials: nickel-coated copper powder can be combined with other materials to make a variety of functional composite materials.

Summary

Nickel-coated copper powder has excellent electrical conductivity and electromagnetic shielding properties, and is widely used in conductive rubber, conductive coatings and other fields. With the continuous expansion of the electronic products market, the demand for nickel-coated copper powder will continue to increase. In the future, with the continuous progress of technology, the performance and application fields of nickel-coated copper powder will also be further expanded.
