Rear Heater Tubes

96 Chrysler Grand Voyager LE - 3.8l 75000 mi - with the auxiliary rear heat and air option. I would like to replace the tubes that feed the rear heater core at the fire wall - they are pretty rusty in spots - the assembly is expensive from chrysler. On my '92 I used heater hose, but the '96 goes over the exhaust... Is there any reason why they do not use copper for these lines originally? Just because steal is cheaper? Copper will corrode too - not sure if it would corrode faster. I assume antifreeze is copper compatible since radiators and heater cores have or used to have copper in them?

The only improvement would be to have them made in stainless steel which would be quite expensive .
