Aluminium-scandium alloys: the key to maximizing performance in heat exchangers.
Manufacturing industrial heat exchangers using aluminium-scandium alloys potentially requires less force during the extrusion process and produces a unit with a superior thermal exchange capacity.
Heat exchangers designed with aluminium-scandium alloys turn out to be more mechanically resistant after brazing, allowing you in turn to reduce the tube thickness or increase the temperature or pressure used in operation.
In some cases, aluminium-scandium can improve the burst pressure resistance of your heat exchanger by up to 80%.
Scandium addition has proven to provide a series of positive effects when it comes to the aluminium alloys used in the heat exchanger manufacturing industry. Not only does it help increase the unit’s mechanical properties, but it potentially ensures a more efficient transfer of heat.
With aluminium-scandium, you’re manufacturing tubes that are resistant to recrystallization and microstructure growth which occurs during the brazing process (short exposure of up to 600⁰C), which cannot be done with traditional aluminium alloys.
Superior thermal conductivity, increased mechanical resistance allowing you to reduce the size of the tubes and the weight of the unit, and greater burst pressure resistance to help you avoid costly production line defects; aluminium-scandium is the key element to stand out from the competition.
