摘要： Extruded tubes for heat exchangers have improved corrosion resistance when used alone and when part of a brazed heat exchanger assembly with compatible finstock. The tubes are formed from a first aluminum alloy comprising 0.4 to 1.1% by weight manganese, up to 0.01% by weight copper, up to 0.05% by weight zinc, up to 0.2% by weight iron, up to 0.2% by weight silicon, up to 0.01% by weight nickel, up to 0.05% by weight titanium and the balance aluminum and incidental impurities. The fins are formed from a second aluminum alloy containing 0.9 to 1.5% by weight manganese or an alloy of the AA3003 type, this second aluminum alloy further containing at least 0.5% by weight zinc.

摘要： A new aluminium alloy containing (in wt.%): 0.2 - 0.5 Fe; 0.7 - 1.2 Si; 1.2 - 1.6 Mn; up to 0.3 Mg; up to 0.5 Cu; up to 0.2 Zn; up to 0.1 Ti is used to make the fins of heat exchangers particularly car radiators. The finstock has high post braze strength and thermal conductivity, and has a sufficiently electronegative potential as to be capable of acting as a sacrificial anode for the heat exchanger tubes. By virtue of the absence of Sn, In and Cr, these heat exchangers can be scrapped and melted for re-use.

摘要： This invention relates to a method of making a composite aluminium brazing sheet, which method comprises: providing a core sheet of a first Al alloy and a cladding sheet of a second Al alloy, wherein a) the composition of the first Al alloy is different from the composition of the second Al alloy, b) the thickness of the core sheet is greater than the thickness of the cladding sheet, and c) the hardness of the core sheet is different than the hardness of the cladding sheet, cleaning facing surfaces of the core sheet and of the cladding sheet; and cold rolling the core sheet with the cladding sheet so as to roll bond them to make a composite aluminium sheet. Also disclosed is a brazing sheet comprising a core layer of a first Al alloy containing Mg and a cladding layer of a second Al alloy.

摘要： A capsule (100) comprising upper (101) and lower (102) parts each having a dished formation (105, 106) and a peripheral rim, the rims being secured together so that the formations (105, 106) are at least partially in register with one another to provide at least one vented chamber (100a), means in at least one of the parts (101, 102) to communicate between the interior of the chamber (100a) and the exterior thereof and the lower part (102) having its exterior so formed as to enable it to be held in stable engagement with a surface but so that a fluid may pass freely between those parts (101, 102) of the exterior of the lower part (102) and the surface that are not in intimate engagement.
