AA5052 Aluminum is an Al-Mg alloy with good corrosion resistance, excellent reliability and cold work ability and strength. The main alloying element of AA5052 is magnesium, which has good forming and processing properties.
This AA5052 Aluminum Radiator is designed to provide maximum cooling efficiency to prevent premature engine failure. Its light-weight, and high-heat transferring aluminum features a tube and fin design that, dramatically increases surface area that enables the heat to dissipate more efficiently. This AA5052 Aluminum Radiator is at least 30%-45% more efficient than stock ones. Most importantly, it has a much higher capacity for coolant than stock ones, which means that your cooling system will be more efficient and will be more resistant to temperature surges in racing applications.
