Silver coated copper product performance and features:

1. Silver coated copper particle size is small, can reach to micron level.

2. Silver coated copper has several kinds of topography, such as spherical, flake, dendrite and so on.

3. Silver coated copper powder has excellent conductivity, can replace silver’s parts of the application.

4. Silver coated copper has good oxidation and dispersion, and can be used in low-temperature slurry and high conductive slurry.

Silver coated copper powder selection recommendations:

1. With the same silver content, the thickness of silver for bigger size silver coated copper is greater then the smaller size silver coated copper. So the bigger size silver coated copper powder has better good oxidation resistance. For example,for a silver content of 30% silver coated copper, the silver layer thickness for 5um is 372nm, while for 1um, the silver layer thickness is 75nm, and therefore, 5um silver coated copper has good conductivity than 1um.

2. The flake powder’s contact area is larger than the spherical one, therefore, the copper flake powder’s conductivity is better than copper spherical. For example: 5um silver coated copper flake’s contact area is bigger than the silver coated copper spherical one, so the flake powder’s conductivity is better than spherical one.

3. Silver coated copper is widely used in the field of low-temperature slurry.
