Applications for aluminium anodizing other than windows/doors


I run an aluminium colour anodizing plant in India. We anodize aluminium extrusions. I am looking to reduce our dependence on the aluminium window/door business. What other high volume markets exist for aluminium anodizing? Are these markets willing to outsource their anodizing requirements?

I'm looking for experiences fellow anodizers have in other countries.

I see finishers in this country diversifying into new technologies, such as powder coating, rather than finding new markets for their existing process lines. I saw one case where an aluminum box, which had previously been anodized, was switched over to powder coating, so it is important to see if your window/door business might move in this direction.

I presume, if you do extrusion work, that you have a large size plant & handle mostly long lengths. I run an anodize facility just outside of NEW YORK CITY , USA, and we do the same as you plus hundreds of other markets. What types of anodize do you do there:

We do all types of anodize including:

etc, there are so many markets. I could write forever.

We also do aluminum chromating as a pretreatment for paint & powder. And, magnesium finishing for aircraft & aerospace industries.

Incidently, many years ago, my father, the founder of our company almost moved to India to setup an anodize plant for a large company there.

Please contact me with any more questions or comments.

It's always nice to talk with a fellow finisher, especially someone far away who isn't a competitor.

I am finding it extremely difficult to source a company that can manufacture a three part casing for a hand held keyboard/ monitor in precision casted aluminium.

Our run will be in the region of 3-400 to start with and most companies in UK and US either are not interested or are prohibitibly expensive.

I have a storm damaged anodized aluminium standing seam roof that needs repair. Unfortunately the anodized sheet (12"x10') is no longer available and we might have to coat the entire 30,000 sq. ft. roof with polyurethane or acrylic to cover the repair.

Does anyone out there know where we can purchase anodized roof panels? thanks, Max Holder

Can't swear to it, Maxwell, but a call to Southern Aluminum Finishers might be worthwhile.

Would you happen to know if any companies that construct subsea equipment, such as in the Oil & Gas Industry, are using anodized aluminum in a long term marine environment? Also, is there any variation in the anodization process that may make aluminum a suitable material in long term marine environments? I'm not familiar with the anodization process and I'm curious to know if there are different types suitable for different applications.

Hello sir,

I am a student and currently doing a project on anodising processes and its applications. And with regard to to this I would like to know the varous applications of sulphuric acid anodising, chromic acid anodising, hard anodising, black anodising, chromating on aluminium alloys, black chromating nickel plating, electroless nickel plating, black alloy nickel plating, gold plating. I understand that you are an expert in these matters and it would be of great help if you can provide some information on the above as early as possible. You can as well give me the sources where I can get the information.

I look forward for your response.

Yours sincerely,
