More than 90% of aftermarket manufacturers use the T-3303 series Aluminum, because it is cheaper and easier to get the material. However, T-3303 aluminum has many disadvantages, such as poor polishing effect, softness, easiness to scratch and corrode, poor heat dissipation effect. If the T-3303 aluminum radiator is operated in high pressure and high temperature for a long time, the leaking problem would occur very soon.Aluminum is an Al-Mg alloy with good corrosion resistance, excellent reliability and cold workability and strength. The main alloying element of. Is magnesium, which has good forming and processing properties. 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. 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.
