I have a Black & Decker CMM1000 5HP 24V cordless lawn mower for years. I am seeking the DC electric motor brushings to replace the pair on the motor. This brushing is spring-loaded, and can be remove by unscrewing the plastic holder. The brush width is half inch. Can you tell me is the brushing material copper? See photo here:

I look everywhere at all the typical hardware stores in Silicon Valley, and they do not have this.

Where should I look for it?

Since you asked, no; brushes are made of carbon.

But looking at the brushing material, it seems metallic and like copper. How is carbon material conductive?

Carbon brush are conductive but have some resistance. Carbon is soft and wears instead of the copper commutator. They have a copper coating to conduct better in their brass (usually) holders.
