Alloy Rad Cores

[Gizmo.Y]

Anybody on here in the know with a supplier for Alloy Radiator Cores?

I Contacted Alisport, And they wanted £240 for a 20x10" Core! Surely they can't be that dear?

yep i think that is about right . i can put you in touch with a pall of mine that specialises in alloy radiators and intercoolers. he dose allsorts of things from fast custom cars to old F1 cars and everything in between . he is very very good.

One off UK made rad cores ain't cheap, not enough info (core thickness, number of rows, all in or + VAT etc) to know if that price is in the ballpark or a bit spendy

Suppliers of rad cores have been discussed a bunch of times, a search of the forum will get more names but Pace Products and NAR Group are gonna be mentioned multiple times

Hello all,

are aluminium radiators better at removing heat than copper, (like for like) or is the benefit a weight reduction one?

possible a cost issue aluminum over copper ?

AIUI it's mostly swings and roundabouts everything else being equal*... copper has waaaaaay better thermal conductivity but the solder used to join all the bits together doesn't. Ally rads are brazed with aluminium so conductivity between the tubes and fins etc is better. The cost advantage of aluminium is mostly negated due to the differences in production... a soldered copper core can be made using simple kit like an acid bath and a solder bath. Ally cores don't really lend themselves to simple methods for low volume/one offs, googling nocolok cab furnace will get more info about the controlled atmosphere brazing methods used

* Can make ally rads with more tube surface area which tips things in the favour of ally i believe
