Need Aluminum finish that looks like stainless steel
Q. We are manufacturers of aluminium fittings for washroom areas, mainly from 6063 extruded sections. We have seen a finish which gives the aluminium the appearance of stainless steel in colour. In order to remain competitive we need to emulate this finish urgently. Can anyone advise us of the process?. Components are all small (150 mm x 20 mm 20 mm maximum)

A. Sir,
We are anodizers of aluminum. A few years ago we had a job which needed to match SS - we had set up a custom anodize dye which matched the color of SS very well - I believe we bought the dye from US Specialty Color or Clariant. The name of the dye was "Stainless Steel". This is your best option.

A. The aluminum can be brushed before anodizing and will retain the brushed finish through the anodizing process. There are anodizing dyes reputed to impart a steel or stainless steel look.

A. Hi Daniel. The way to do this yourself is to mechanically polish & buff the aluminum, then clearcoat it. It will be whiter than the blue-ish color of stainless steel, but it can look nice.
It is impractical to chemically bright dip the tubes because it requires a highly toxic, almost boiling mixture of nitric and phosphoric acid, followed by anodizing them, and dyeing and sealing them. This is an industrial process that can't be done at home by a consumer.

Aluminum finish to look like matte-polished stainless steel
Q. We are manufacturing furniture made from aluminum pipes. Our buyer has requested us to find a way/technique to finish aluminum parts to look like matte-polished stainless steel pipes. Is there any chemical process or anything at all that can achieve that?

A. Try a matte anodize with a dye to approximate the color of stainless steel. I think letters 1720 and 31135 cover this same topic.
Good luck.

Ed. note: Those two threads are now incorporated into this one; Jim is referring to David's response to Tony, and Ted's response to Nilesh, above.
A. You should try a process called Alfisteel from a company called Alufinish in Germany. It produces the closest colour to stainless steel I have seen.

Making an aluminum casting look like stainless steel
Q. I work for an aluminum die caster, producing aluminum A380 castings for the automotive, electronics, appliance, furniture and defense industries. We have been chromating, painting, anodizing, and otherwise finishing our parts for years.
However, we recently came across a customer requirement for which we have been unable to find a cost effective solution. The part we produce is a handle that mates to a stainless steel component. For aesthetic reasons, our customer wants the parts to match. No consideration will be given to making the stainless component look like the casting.
Unfortunately, our time is SHORT. We have been seeking help from our customer for months, assuming that they have had this done before and could help us find the appropriate source/process. Now that sample parts have been delivered, our customer understands the magnitude of the problem. We now understand that they have NOT done this before. We have about a week to find a solution.
We realize that paints can be formulated to match fairly closely, but with our customer's requirement, we are finding that it has to be formulated from scratch, potentially taking months. We don't have that time.
Is there a cost effective process out there that can make die cast aluminum LOOK like stainless steel? The alloy contains about 9.5% silicon, and tends to cause some finishing options to darken as a result. We need a process that can be uniform and repeatable - AND match the look of the mating component.

A. Electroless Nickel (EN) might be the closest match. Not easy but totally doable for a good plater specializing in plating EN on aluminum. G. Marrufo-Mexico

A. You probably also want the protective equal of stainless steel, therefore, the best alternative, however long it takes, is definitely powder paint that has been blended to match.

Aluminium pipe polishing to look like steel
Q. Hello.
I want to know if it is possible, how can we give aluminum pipe the look of steel? Please tell me if you can?

A. Good day Sikander.
You wish to "give aluminum pipe the look of steel? Please tell me if you can?"
Steel can be polished, it can be stainless--very bright, smooth, lustrous, or it can be black pipe.
What is it that you need to accomplish? What type of aluminum are you processing? You can electroplate the aluminum with nickel and chrome, etc.
More info would be helpful.
