WHich IS better COPPER brass or ALuminum?

[dlinker]

anu b advantage and disadvantage between the two? by the toyota corolla 1997 XL manual car ko.. tnx tnx)

radiator po ba or evaporator

sa raditor mas ok ung copper

sa aircon evaporator mas ok para sa akin ung aluminum

for coins, copper looks better. if you want something harder than copper, brass will do. but for airplane wings, nothing beats aluminum.
but for radiators, evo says copper is better if you intend to keep the car for a long time.

for radiators, copper. you can always do an emergency repair using "Stop-Leak" radiator leak repair.

for air con condensers and evaporator, i'm old school when it comes to air conditioning so i'd also go with copper and brass. with decent gas welding skills anyone can weld copper or brass. with aluminum, good luck! bring the flame too close and all you will have is some scrap aluminum with a bigger hole than when you started. it takes years of practice and expert tutoring to learn how to gas weld aluminum. unfortunately all the condensers and evaporators out there are now all aluminum, so just throw away when damaged and buy a new one.

Valuewise aluminum radiators are a good deal. Repairability and durability under our conditions and water/coolant quality, copper/brass works best.

Actually for A/C's copper works better but they have become prohibitively expensive. But a copper evaporator will give you the added benefit of better cooling, and since copper and most of its alloys are naturally bacteriostatic, you don't get that dank locker-room smell from your A/C.

And as yebo said, it can be repaired. The problem in some cases when repairing aluminum heat exchangers even with the new alloys is that you end up annealing the adjacent areas of the joint/hole you're plugging, thereby weakening them.

Actually in "copper" radiators the tubes and tanks are actually made of brass. Copper would be too soft in those gauges to be of any structural use.

[yebo]

hard drawn copper naman mostly, much stronger than soft drawn copper.

^You're referring to A/C components.

No wonder old Benz evaporators are made of copper/brass. Very sturdy components.

That and copper was still very economical back then.

Aluminum, especially in heavy applications have been prone to stress fracturing too.
