Brass Materials for Cycles. I used these materials for an architectural project with a lot of post production in Photoshop, so the material nodes themselves are very simple (without even a displacement map or thelike). Therefore they will render quite fast, but for other projects you might want to add displacement maps, more shaders etc.
I think the useful part here are the included two different tiled brass textures of 3264x3262px. Have fun, and if you make something cool out of it, post it here!
Please note: 1) this is not a “renderable” test scene, you will have to append or link the material to your own file. 2) the weathering and scratches on the brass make a very vivid texture, as a consequence the tiling will look ridiculous if you overdo it
