New Technology for Copper and Brass Radiators

Three new technologies so improve copper and brass radiator production are now being pursued in the U.S.A.: Automated core baking significantly improves the reliability of soldered joints; zinc-base solders cars provide much higher mechanical properties and lighter weight than conventional lead alloys, with no “blooming corrosion” or toxicity hazards; and mechanically clinched brass tank-to-header joints promise better reliability than conventional soldered designs. These technologies, ready for commercial exploitation, will make available copper and brass radiators that are lighter, more durable, more efficient and lower in cost than today's products
