If light weight and high performance are your ambitions, then selecting aluminium for your HVACR application will provide you with equipment lighter than devices using copper tubes – and you will always benefit from the space saved.
Aluminium density is one third of copper. Eventhough tube walls need to be thickened to compensate aluminium mechanical resistance, weight savings over copper is more than 30% for equivalent burst pressure.
