Do you mean black dyes or refer to black machining? If it is the former, there are a few to more than 1,000 dyes. If the latter depends on what material you are, 1000-6000 per ton is possible, depending on your material weight
What kind of profile you are, is it small or large? What is the surface area? How long? Is it electrolytic or black? Then you can get the price. It, if you are interested, you can contact me. I am in Suzhou's aluminum oxidation plant, which can be done by electrolytic coloring and dyeing.
Black anode oxidation is calculated according to square meters, about 10 yuan per square meter.
