I've done some research myself and only found ones with plastic tanks. I think it has to do with expansion rates and leak problems because of this. I know Corvettes and Cadillacs had problems with their all-aluminum radiators.

There is only one reason for a rad to explode. Too much pressure, be it rad cap or blown head gasket. If the rad cap holds too much pressure or not enough causing steam to build up, either one is a problem.
A stuck thermostat could cause overpressure also.

Replaced the t stat and rad cap and water pump and re sealed them all right before the radiator exploded. And it doesn't eat any water at all. But got a new radiator and it don't over heat anymore so I guess problem solved lol
