Advantages

Main advantage: mechanical strength of K65 material; because of this, the K65 product series for 120 bar can be made with comparatively thin walls
K65 tubes can be brazed to K65 fittings manufactured by IBP Conex | Bänninger
The light weight of pipelines made of K65 means not only a significant saving in material, but also easier handling, for example when mounting the tubes on ceilings
Excellent processing properties which are similar to those of copper
High tensile strength and yield strength even after brazing and at high temperatures
Processible on existing machinery: brazeable, bendable and expandable
Excellent corrosion resistance
