The present invention provides a method for producing AlMn strip or sheet for making components by brazing, as well as the products obtained by said method. In particular this method is related to fin materials used in heat exchangers. The fins can be delivered with or without a cladding depending on application. Rolling slabs are produced from a melt which contains 0.3-1.5% Si, 0.5% Fe, 0.3% Cu, 1.0-2.0% Mn, 0.5% Mg, 4.0% Zn, 0.3% each of elements from group IVb, Vb, or VIb elements, and unavoidable impurity elements, as well as aluminum as the remainder in which the rolling slabs prior to hot rolling are preheated at a preheating temperature of less than 550 C., preferably between 400 and 520 C., more preferably between 450 and 520 C. to control the number and size of dispersoid particles, and the preheated rolling slab is hot rolled into a hot strip. The strip is thereafter cold rolled into a strip with a total reduction of at least 90%, and the cold rolled strip is heat treated to obtain a 0.2% proof stress value that is 50-90% of its proof stress value in the as cold rolled condition to a proof stress value in the range between 100 and 200 MPa. The strip may alternatively be produced by twin-roll strip casting. The composition of the melt tailors the microstructure development during the complete processing to give the desired post braze properties and performance during brazing in combination with adequate delivery properties of the strip. In particular the high post braze strength combined with a good sagging resistance and low susceptibility to liquid core penetration during brazing, as well as a relatively good formability in the delivery condition prior to fin forming.

The invention relates to a multilayer plain bearing element (14) composed of a composite material comprising a supporting layer (2), a binding layer (3) connected to the supporting layer (2), and a bearing metal layer (4) connected to the binding layer (3), wherein the binding layer (3) is composed of aluminum or a first, soft-phase-free aluminum-based alloy and the bearing metal layer (4) is composed of a second aluminum-based alloy containing at least one soft phase, and the binding layer (3) and the bearing metal layer (4) are connected to each other by means of a fusion-metallurgy connection in such a way that a binding zone arranged between the bonding layer (3) and the bearing metal layer (4) is formed, wherein grains (9,10) are formed in the binding zone and a continuous grain boundary course between the binding layer (3) and the bearing metal layer (4) is formed in the binding zone.
