Abstract (en)
[origin: WO2009043993A1] The invention relates to an extruded product, in particular a tube, made from an alloy of composition (%, by weight): Si: < 0.30, Fe: < 0.30, Cu: < 0.05, Mn: 0.5 - 1.2, Mg. 0.5 - 1.0, Zn: < 0.20, Cr: 0.10 - 0.30, Ti < 0.05, Zr < 0.05, Ni < 0.05, others <0.05 each and <0.15 in total, remainder being aluminium. The invention further relates to a method for producing extruded tubes with said composition, comprising casting a billet, optional homogenisation thereof, the extruding of a tube, the drawing of said tube, in one or more passes and continuous annealing at a temperature between 350 and 500°C with a temperature rise of less than 10 seconds. Said tubes are used to advantage in cabin air-conditioning systems for motor vehicles using CO2 as refrigerant gas.
