Main products group

Gränges offers a full range of rolled aluminum products for heat exchanger manufacturers, and up to 3, 000 product specifications. Including 200 active alloy combinations. Leading-edge technology and true industrial craftmanship ensure material with consistent quality. The products can be divided into four main groups: Clad tube, Clad fin, Unclad fin and Clad plate.

Clad tube

Tube products for both welded and folded tube designs supporting the continuing trend for downgauging and incressing demands on corrosion resistance, brazeability and strength.

Clad fin

Clad fin developed for excellent brazeability to withstand core dissolution and high-temperature sagging,and to enable downgauging for lighter heat exchangers.

Unclad fin

The most basic heat exchanger material. Unclad fin comprises only one alloy without clad layers and is used for applications such as radiators, heaters, charge air coolers and evaporators.

Clad plate

Consists of a core alloy clad with braze clad on one or two sides. The rolled product is stamped or shaped by the customer depending on the application and used in most kinds of heat exchanger applications, either for coolant plates or manifolds.
