I recently saw a TV "how to" show about finishing copper with Ferric Chloride (etchant) mixed with water and another mixture of copper nitrate (oxidizer) plus zinc chloride and water. Also, the right alloys of aluminum can be anodized without losing substantial shine - most dentists' lights and outdoor lighting reflectors, and many telescope mirrors are anodized aluminum.Ī. Aluminum can be clearcoated lots of people polish their aluminum car wheels then clearcoat them. Could anybody tell me if there is a coating one can apply to stop brushed aluminium anodising outside and keep up it's sheen.Ī. Will this patina hold up to the elements? Jim Johnson I have a project in which an aluminum piece will be outside. Hint: make the copper sulfate is very diluted. Reaction: turn the gray stuff to black and a little bit of red shade. Reaction to aluminum: turns the aluminum gray. Solution a: sodium hydroxide and zinc oxide Rubber gloves protective chemical gloves Try this, just make sure your wearing neoprene Here is an old school way of coloring aluminum man. Hope it helps and good luck! Goran Budija
Instead of oil you can use 2-20% shellac solution too. Simple and effective solution-oil it very very slightly with any edible oil(according to old books olive oil is best),then heat it to 300-400 ☌ (use hot air gun). Copper prices are sky rocketing so I was wondering if there is a glaze, transparent metal paint or some inexpensive way to add a new COPPER look to aluminum (no patina. If I was GM of the Universe it would be a shooting rime to color aluminum zippers to make people think they are copper or brass :-)
#ALUMINIUM BRONZE PATINA ZIP#
The white salty growth, the corrosion pits, and general galling made it impossible to zip after just a weeks, and I always had WD-40 running over the window and down the paint in a vain attempt to render it functional at the same time the brass zippers on my boat were working fine. I bought a replacement convertible top for my Geo Tracker which came with an aluminum zipper disguised to look like a brass one.
Please be very careful about trying to make aluminum look like copper or brass because it doesn't function like it :-( But I don't think you'll find any method of getting a consistent color without completely unreeling it and doing continuous web processing. You can coil anodize & dye it to achieve the effect. I would like the chime finish to be durable and to look good in the garden. A bronze, copper, yellow, red, green, olive, black, brown or combination of colors would work. Ideally some chemical I could put on them and heat to produce some earth tone color or colors. I would like to add color with out painting or anodizing. So far I have been turning them on a lath while holding sandpaper on them to give them a brushed stainless steel look.Then I spray them with a coat of silicone oil to preserve the look. I am building some wind chimes out of aluminum tubing. I have brushed aluminum tube to patina in earth tone You can post an RFQ what what you are seeking at Depending on how close it needs to look, anodized aluminum with an "oxidized copper" colored dye or paint/powder will do it. Less expensive, but looking exactly like real copper (because that's exactly what the surface is) would be copper plating. As copper is expensive I am trying to find an aluminum fabricator who will build the surround and then attempt to apply a finish to make it look like copper that is oxidized.Ī. I am hoping to have a metal surround for my existing brick fireplace. Please tell us what it is (and how many) you want to patinate because this site serves hobbyists who want to make one, and manufacturers who want to make millions, and answers will be different for different needs. But read their instructions on-line before buying or starting the project because sometimes it's a two or three step process with a ground coat, then a main coat, then a reactive coat that patinates the main coat, etc. That is done by "painting on" a coating of copper and its reaction products.įurther down the page you'll see responses to Jasper L where commercial products are linked. Although a passable job can be done with paint if you're speaking of a roof or gutter, and you can buy that painted aluminum sheet metal, for closer-up stuff you'll probably want a real copper patina.
