Seawater corrosion resistant aluminum alloy heat exchange tubes

I heard that aluminum alloy tubes can be used as heat exchange tubes for seawater heat exchangers. I wonder which brand of aluminum alloy pipe has better corrosion resistance in 70-degree seawater? Thanks!

Domestic Henan Dechang Copper and Aluminum Profile Co., Ltd. produces aluminum alloy heat exchange tubes that are resistant to seawater corrosion. It is said that its resistance to seawater corrosion is close to that of titanium alloy.

Is there any reason to use aluminum alloy heat exchanger? In fact, the seawater corrosion resistance of graphite heat exchangers is higher than that of aluminum alloy and titanium heat exchangers. The heat transfer coefficient of graphite is also higher than that of titanium, and the equipment price is relatively low.

Thanks for the help! Excuse me, can you provide the specific brand and approximate price?
