What metal composition is in percussion caps?

[Darth-Vang]

What metal is percussion caps made of? Pure copper? Gilding metal? Anyone knows? Just curious. As I intend to make my own percussion caps.

I use aluminum pop cans. Drink the pop and recycle the cans into caps.

Yeah, I know I can use pop cans. But I prefer copper. Plus I already made some copper percussion caps. I used the recommended .005” copper sheets or 36 gauge sheets. But I’m hoping to use the correct copper or alloys.

Hello Darth-Vang,

I can't tell you what they are made of,
but I do know Remington's seem softer than CCI's.

Methinks you're better off with copper. I don't think they will frag as much as brass caps. Original caps were copper and thicker than modern caps.
