Kaltra deploys new aluminum alloy for microchannel heat exchangers

Kaltra completed the pilot study for a new, highly corrosion-resistant aluminum alloy, AA3F05, temper H112, to be used in its microchannel heat exchangers. SWAAT (Sea Water Acetic Acid Test as per ASTM G85 Annex A3) tests performed during the deployment phase demonstrated that AA3F05’s lifespan is more than double that of the currently used HA9153 alloy.
