Aluminium for a radar arch?

I was going to do stainless steel, but I am having issues finding someone to bend it for reasonable costs.
I know aluminium does not keep a shine like stainless steel, but I guess I could paint it, like I am painting my masts, and the black would match. Any reason I could not use it? Would be for an arch, dinghy lifts, and cockpit.

Re: Aluminium for a radar arch?

My arch is ali. Carries my solar panels and I use it to hoist the dink at night.

About 9 years old now and although it has the odd scuff still looks good.

Re: Aluminium for a radar arch?

My friends Radar arch/davits after 15 years of service started to bend under the weight of the dinghy. He took it to a welder to try to get it straightened and reinforced, only to find the aluminum was deteriorating from the inside and was not weldable. Though I have seen a lot of them made from aluminum.

Welcome funset
Their are many types of aluminium, some grades are more suited for marine life then others, thats for sure. That one sounds like it corroded, some will do that when exposed to moisture for a long period of time.

Re: Aluminium for a radar arch?

There is a product that you wipe on aluminum and it instantly restores the finish to make it look brand new. Sonus Aluminum Restore, aluminum cleaner, metal spray polish, bare aluminum cleaner
