摘要： The invention relates to an aluminium composite material having at least one core layer of an aluminium core alloy and at least one corrosion protection layer arranged on the core layer. The aluminium composite material has improved corrosion resistance, in particular avoids coarse detachments under corrosive conditions, through use of a corrosion protection layer with the following composition in wt %: Si≤0.10%, Fe≤0.6%, Cu≤0.2%, 0.9%≤Mn≤1.2%, Mg≤0.10%, Cr≤0.3%, Zn≤0.1%, Ti≤0.1%, the rest Al and unavoidable impurities, individually at most 0.05%, in total at most 0.15%. The invention furthermore relates to a method for producing an aluminium composite material, a use as well as a heat exchanger or a component of a heat exchanger.

摘要： The present disclosure provides an aluminium material for the manufacture of high-strength, soldered components, including an aluminium alloy. After soldering, the aluminium material is in materially-bonded contact with at least one solder layer. The object of providing an aluminium material is to provide not only good soldering properties and formability, but also high strength. This is achieved because the aluminium alloy of the aluminium material has a solidus temperature, and the aluminium material has an increase in yield strength compared to the state after soldering and cooling.

摘要： The present invention relates to a hydrogen-storing composite material which is convertible essentially reversibly between a storing state and a non-storing state, wherein the reaction enthalpy in this conversion reaction can be set in a targeted manner to a value between 15 and 80 kJ/mol of H2, preferably 25 to 40 kJ/mol of H2. Hydrogen-storing composite materials are characterized in that, in the storing state, they comprise at least one complex metal halide of alkali metal or alkaline earth metal and an element of main group three of the Periodic Table of the Elements and also at least one complex metal hydride of alkali metal or alkaline earth metal and an element of main group three of the Periodic Table of the Elements, or in the storing state at least one metal halohydride of alkali metal or alkaline earth metal and an element of main group three of the Periodic Table of the Elements, and in the non-storing state, at least one alkali metal halide or alkaline earth metal halide and a metal of main group three of the Periodic Table of the Elements.
