    Abstract: The invention relates to a solder powder for connecting components made of aluminium or aluminium alloys by brazing, in particular a brazing powder for connecting heat exchanger components. The solder powder consists of powder particles on an aluminium-silicon base having a weight fraction of more than 12% by weight of silicon, wherein the powder particles have been produced by a rapid solidification and contain uniformly distributed silicon primary crystal precipitations in the eutectic aluminium-silicon alloy structure. Coating with such a solder powder leads to a uniform distribution of the silicon on the surface of the component coated with solder powder and thus to the same good soldering results.

    Abstract: The tamperproof closing device for a receptacle having a threaded collar comprises a screw cap (1) consisting of a bottom (8) and a cylindrical skirt (9) having inner threading for co-operation with the corresponding threading (5) on the collar (2) and extended by a tamperproof ring (13) which is attached by frangible means (20). The collar has a plurality of outer radial notches arranged at the base thereof. Said notches are circumferentially oriented and the ring comprises a plurality of inner radial reliefs (15) whose profile is complementary to that of the notches (7). The orientations and dimensions of the notches (7) and reliefs (15) are determined in such a way that the second items can pass onto the first items in the direction of screwing as a result of elastic deformation of the constitutive material and can prevent the same from occurring in the opposite direction. The reliefs (15) are formed on an annular lip (14) which is turned back and originates from the tamperproof ring (13).

  • Publication number: 20030029533
    Abstract: An aluminum alloy article containing the alloying amounts of iron, silicon, manganese, titanium, and zinc has controlled levels of iron and manganese to produce an alloy article that combines excellent corrosion resistant with good formability. The alloy article composition employs a controlled ratio of manganese to iron and controlled total amounts of iron and manganese to form intermetallic compounds in the final alloy article. The electrolytic potential of the intermetallic compounds match the aluminum matrix of the article to minimize corrosion. The levels of iron and manganese are controlled so that the intermetallic compounds are present in a volume fraction that allows the alloy article to be easily formed. The aluminum alloy composition is especially adapted for extrusion processes, and tubing that are used in heat exchanger applications.
