Welded aluminum tubes have been the mainstay of the aluminum radiator and heater core processes for the last 30 years or more. Whether your aim is to get the highest strength tube that is still CAB brazable, or the most corrosion resistance possible, Arconic has the perfect alloy for your application.
Arconic's patented approach using titanium for corrosion resistance allows for two separate corrosion mechanisms to protect your tubes for a long life material solution. If even more corrosion resistance is required, a multi-layer material can be used to provide best-in-class corrosion resistance.
Both Arconic's standard long-life and multi-layer materials are available with variable levels of magnesium to meet strength and brazability requirements.
