Gränges’ research and development portfolio

Some examples of current research projects that Gränges also offers commercially to its customers are listed below.


A product developed in collaboration with Sandvik. The material makes the brazing process possible without the need to add flux salt. This allows customers to overcome many limitations and high costs related to the traditional brazing process, where the application of flux salt is needed.

Strong-sagging-resistant fins

This technology allows customers to downgauge fin materials and/or apply tougher brazing cycles without compromising quality and performance.

Exhaust gas re-circulation (EGR)

Requirements for lower engine emissions are continuously increasing. Engine exhaust can be extremely corrosive due to its high acid content (sulphur). Gränges is focusing on material validation in this area.

Gränges’ research and development efforts have resulted in 52 patent families and 168 patents (as at December 31, 2016).
