Technical leadership

Over the years, Gränges has developed four specific competencies, that have contributed to the company’s technical leadership within heat exchanger materials: alloy development, cladding, rolling and thermo-mechanical processing, and slitting.

Alloy development
Gränges has excellent expertise in developing alloys and combinations with properties specifically adapted to each step of customers’ manufacturing processes – from forming to assembly and brazing.

Cladding
Cladding is a key capability that provides high added value and differentiates Gränges from manufacturers of rolled products for general use. The company produces single- and double-sided clad products, and symmetrical and asymmetrical products, with many different alloy combinations.

Rolling and thermo-mechanical processing
These are used to alter alloys’ microstructure to achieve desired properties of the end product. Gränges has extensive experience of thermo-mechanical processes, and their effect on the performance of materials in the brazing process.

Slitting
Gränges has market-leading competence and experience in slitting technologies that play an integral role in manufacturing heat exchanger materials.
