Reasons for choose our AA5052 Aluminum Radiator:
1.Our
Radiator is made of AA5052 aircraft aluminum, AA5052 Aluminum major
alloying element is magnesium,has a higher strength and greater
corrosion resistance (including to salt water).
2.Higher density core:
cooling rows are spaced 3/8" apart,giving you 25% more rows within the
core than other aluminum radiators sold on eBay.
3.14-16 cooling fins
per inch,giving you approximately 1500 more cooling fins than other
aluminum radiators.AA5052 aluminum radiator core can be made more
efficient by changing the tube spacing and fin count. If the tubes are
placed closer together and the fins are packed in tighter a denser core
is created that throws off much more heat. A high efficiency core can
have tubes on 3/8" centers and fin counts increased to 14 to 16 FPI,That
may not seem like a big deal but the surface area is greatly increased.
Combined with all the additional fins between the tubes this provides
approximately 30% to 45% better cooling than the OEM radiator had.
The core of the
radiator is welded in vacuum brazing furnace, no epoxy.The Radiator are
100% welded by TIG.Stronger & Higher Capacity for Coolant than OEM
units,Made of High Quality Full AA5052 Aluminum Construction.aluminum
radiator is designed to provide maximum cooling efficiency to prevent
premature engine failure.
