Advanced products in close cooperation with Alecoil

Gränges is focused on rolled products for heat exchangers and selected niche applications. Gränges offers a comprehensive range of clad and unclad rolled aluminium products applications with a high degree of functionality and performance.

Depending on the specific needs of a given application, Gränges offers multi-layer products with up to five layers. This variety provides virtually unlimited possibilities  for customised solutions based on carefully selected alloy combinations, delivery conditions, cladding thickness and geometries.Leading-edge technology and true industrial craftsmanship ensure materials with consistent quality.  Over the years, Gränges has developed a large number of products with improved end-characteristics, increased stability and enhanced sustainability. Many of these products are based on new concepts such as SSR fin and TRILLIUM Gränges’ focus on technology,  manufacturing processes, and material properties contribute to creating lighter and more designable materials that increase economic efficiency and reduce environmental impact.
