I bought 2-280 PE EK kits 1.5 years ago
Came with 280CE radiators
Never looked into what the radiators were made of...
But noticed this after someone posted it
Not that the corrosion was caused by the radiators maybe silver kill coil and nothing else to prevent corrosion.
But kind of got me wondering about the materials ek used to make their radiators
Copper fins is that the 90% claim ?
Or are the tubes or water channels copper with coatings like maybe nickel.... or aluminum with some type of coatings inside ?
Or are the inner channels aluminum and black paint outside ?
I read also ek saying don't use harsh chemicals to flush system out
Is that to protect the radiators and or nickel plating in other stuff like water blocks.. ?
By the way I don't want to debate cooling efficiency copper verses ek rads so just an honest question of materials used by ek in their radiators.
