1. What is Silver-Coated Aluminum Powder?

Silver-Coated Aluminum Powder consists of an aluminum particle core covered with a controlled layer of silver. This structure combines aluminum's lightweight properties with silver's excellent electrical conductivity.

2. Why coat aluminum powder with silver?

Silver coating can significantly improve the surface conductivity and electrical contact characteristics of aluminum while maintaining a substantially lower density than using equivalent quantities of solid silver.

3. What silver coating levels are available?

Silver loading can be customized depending on the required conductivity, surface coverage, cost target, and application. REG Metals can provide different silver-to-aluminum ratios upon request.

4. What particle sizes are available?

Common particle sizes include:

• 1–5 µm
• 5–15 µm
• 10–30 µm
• 15–45 µm

Custom particle size distributions are available.

5. What applications use Silver-Coated Aluminum Powder?

Typical applications include EMI shielding, conductive coatings, conductive polymers, electronics, telecommunications, aerospace electronics, thermal management, and advanced composites.

6. Is Silver-Coated Aluminum Powder electrically conductive?

Yes. The silver coating provides a conductive surface and can improve electrical conductivity compared with uncoated aluminum powder, with performance dependent on coating coverage and loading.
