Brass

[Dropout]

Hi All

Is there a preferred type of brass for routering/engraving. I need to quote on about 60 plaques size 13 by 4 inches. They will need to be plated afterwards.

Any advice is welcome.

in advance.

Ask for 'Engraver's Brass'/'Engraving Brass'...engraves well..

I'd love to hear how that goes. We have a CNC but always use Gemini for plaques. I've never thought of doing it ourselves. Please keep us updated.

We do a lot of brass plates/plaques on the router and engraver.

Cut them out and drill holes with the router, sometimes engrave them with the router as well as the engraver.

"leaded" brass engraves MUCH nicer than regular brass, we find the regular stuff leaves burrs on the edges of the lettering on our rotary engraver.

If your Going to have them Plated anyway I would use Aluminum. 5000 and 6000 Series Alum machines great.. Anything lower has a tendency to gum up your bits.

1mm...? we use only 3mm, and keep a sheet or two of the 2000 x 600 size engraver's brass on hand.
My experience with thinner stuff is the headaches & gremlins that sneak in are not worth the minor substrate cost saving- besides a plaque in real brass, as opposed to gold-coloured aluminium, looks better with some gutsy depth to it.

Chrome plating the plaque afterwards? yuk!
We chrome plate brass horse harness elements, but a plaque is different. They're meant to be read - a message understood - as opposed to being 'pretty bling'.
