Our Radiator is made of AA5052 aircraft aluminum. Its different from other sellers T-3303 Series. In fact, AA5052 series Aluminum is much better than T-3303 series.
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.
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. It is widely used in the manufacture of aircraft fuel tanks, oil pipes, and sheet metal parts of transportation vehicles and ships, hardware products, and electrical-appliance casings.
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.
1. Made from Aircraft AA5052 grade aluminum for prolonged lifespan and with raw aluminum finish
2. Brazed core technology to guarantee optimum performance and dependability
3. All AA5052 Aluminum 2mm thick tanks and fittings,Ensure it's hard and durable
4. Billet Aluminum CNC machined fill neck rugged and durable
5. OEM style brass petcock drain much better than other plastic one on eBay
6. Carefully crafted to exceptional OE standards for precise fit
