Spherical Silver Clad Copper Powder Description
Spherical silver-clad copper powder is a composite powder consisting of a copper core and a thin layer of silver. It possesses high temperature resistance and chemical corrosion resistance. It can be used as highly conductive thermal conductive fillers and electromagnetic wave shielding materials in polymer materials. Silver-coated copper powder's fine particle size can be used to develop high-conductivity ink for the printing of circuit board circuits. Silver-coated copper powder can be compounded into ceramics and other metal powder materials to improve the electrical and thermal conductivity of composite materials.

Spherical Silver-Clad Copper Powder FAQs
1. How is the conductivity of silver-clad copper powder?
Silver-clad copper powder achieves conductivity close to pure silver (>80% IACS). The silver coating provides excellent electrical properties, while the copper core maintains cost efficiency.
2. What are the advantages of silver-coated copper?
The silver coating combines high conductivity with copper's cost advantages. It prevents copper oxidation for extended material life and offers 30-50% cost savings compared to pure silver powder.
3. What can be 3D printed with silver-clad copper powder?
This material can be used to 3D print electronic components like sensors and RF parts, energy system components including battery electrodes and fuel cell elements, and complex thermal management structures. Note that metal 3D printing processes like SLM are required for these applications.
