Mines a couple years old now and good as new, they did a discount if you mentioned pistonheads when I got mine.

I was in a similar position a while back when my Griffith rad failed for the 3rd time in 17 years.
I was considering fitting an aluminium one until the local radiator specialist advised against it.
He explained that the copper/brass rad in the car can tolerate a fair degree of movement before failing by splitting whereas an Aly one is far less rugged and will split if moved a little as said above.
Which ever you chose leave plenty of room for movement in the bottom mounting lugs, I even put some weak springs underneath the lugs to help. It seems to have worked.

Henley Heritage fitted a replacement aluminium one to mine when it was 7 yrs old according to the history. 25k miles and 9 years later, it's still fine. (£370 + VAT for the radiator in 2007!)
Personally I think an aluminium one may be more robust / resistant to stone damage. The fins seem less flimsy than other copper ones I've encountered.

the big problem with alloy rads is that the conductivity of alloy is considerably lower than copper so for the same cooling effect the rad needs a larger surface area, which you can do in a chim make it thicker, second problem is they dont like flexing which is not good in our cars as the thing is flexing all the time particularly under track conditions, ally rads are popular in motorsport applications when building limited numbers the alloy rads are far easier to build plus they are usually fitted to a bespoke frame integrated with chassis so less chance of flex be advised just go for recore or new rangy rad.

Aloo-min-um for me too. Old rad was knackered and Powers fitted the aly one. So long as it is dead flat when tightened down, it will be okay. Dom says and Dom's warranty good enough for me.

Ignore us amateur keyboard jockeys by all means.
But take Engineer 1949 seriously.
I have yet to find any engineering matter about which he doesn't know everything.
He has, to my knowledge, built a Chimaera 4 litre SC from the ground up, and is presently engineering a very powerful Cerbera. And there's a complete Wedge rebuild in there somewhere too

Just like us keyboard warriors Anthony, experts also have differing opinions.But take Engineer 1949 seriously.

M'lud, the defence will now produce 2 experts who will argue that the prosecution witnesses are misjudged......
Op, not sure where you are located but I have a spare original if you want to get that refurbered and give me back your old one after if that helps? My last car had a couple of rads and it was due to poor fitting by the previous owner. Dan Taylor opened up the mounting holes and all good with the alloy rad he put in several years ago.
I changed this cars rad to alloy and if I have any problem with that in the future, it will be back standard for me.

To early yet (reliability wise) but went ally for the weight saving and there is quite a difference IMO cant comment on cooling differences as never had any before and its just the same now, both Phazed and I run the same rad so we will see his car obviously gives it more of a workout
