Verdict: pick brass for the listings here: the Sunkoo 99.9% pure brass sheets for plates and tags, or the Rainteam solid brass coins for commemorative pieces, with the protective coating removed before engraving.

What the brass listings state
The two listings here are both brass, so they show what a brass engraving listing looks like. The Sunkoo states 99.9% pure brass in 4 by 8 inch sheets, 20 gauge and 0.8 mm thick, film-protected on both sides. The Rainteam states solid brass, non-electroplated brushed, in 40 mm coins, 3 mm thick, with a protective coating the listing says to remove before engraving.
Neither listing states a warranty term or a safety listing. The Sunkoo names engraving, stamping, jewelry making and model building; the Rainteam names stamping, etching and laser engraving for coins and medals.
The bronze side
No bronze listings are featured here, so there is nothing to score on that side. If your project calls for bronze, check the listing for the same attributes these brass listings state: the alloy, the thickness, the surface finish and whether a coating must come off before engraving. A listing that states none of those leaves the choice unclear.
Choose brass if
- You want plates or tags: the Sunkoo sheets are 4 by 8 inches, 0.8 mm, stated 99.9% pure brass.
- You want coins or medals: the Rainteam blanks are 40 mm solid brass with an acrylic box each.
- You want stated engraving prep: the Rainteam listing says to remove the protective coating before engraving.
Choose bronze if
- Your project calls for bronze rather than brass.
- The bronze listing states the alloy, thickness and finish as clearly as these brass listings do.
- You have checked the listing for any coating to remove before engraving.

FAQ: lasers and CNC
Can you laser engrave brass?
Yes, per these listings. The Sunkoo sheets are stated for engraving and the Rainteam coins for laser engraving, with the note to remove the protective coating first.
Can you laser engrave bronze?
These listings are brass, so they say nothing about bronze. Check the bronze listing for the alloy and finish, and confirm engraving use the way the Rainteam listing states laser engraving.
Do I need to remove the coating before engraving?
For the Rainteam coins, yes: the listing says removing the protective coating before engraving gives better results. The Sunkoo sheets arrive film-protected; the listing does not state engraving prep.
Brass sheets or brass coins?
Sheets for plates, tags and jewelry blanks; coins for commemorative pieces. The Sunkoo 2-pack covers larger flat work, while the Rainteam 10-pack covers batches of coins.
What should a metal listing state?
Alloy or purity, thickness, size and surface finish, like the 99.9% pure brass, 0.8 mm thickness and film protection on the Sunkoo listing. A listing that states none of those leaves the choice unclear. See our how to choose a laser engraver guide.
