  • Publication number: 20110089047
    Abstract: A cadmium-free, zinc-based alloy suitable as a sacrificial anode substantially consists of 0.4-0.6% by weight of aluminum, 0.02-0.03% by weight of indium, max. 0.001% by weight of cadmium, maximum 0.005% by weight of copper, maximum 0.006% by weight of lead, maximum 0.0005% by weight of tin, maximum 0.10% by weight of other metals, in particular nickel and thallium, and balance zinc having a purity of about 99.995% The alloy shows advantageous properties with respect to resistance to cracking and breaking during post machining of the casting, especially when producing sacrificial anodes having relatively small dimensions.

  • Patent number: 6280795
    Abstract: An alloy for galvanizing steel comprises, by weight, aluminum in the amount of at least 0.001% to 0.007%, preferably 0.002 to 0.004%, tin in the amount of at least 0.5% to a maximum of 2%, preferably at least 0.8%, and one of an element selected from the group consisting of vanadium in the amount of at least 0.02%, preferably 0.05% to 0.12%, titanium in the amount of at least 0.03%, preferably 0.06% to 0.10%, and both vanadium and titanium together in the amount of at least 0.02% vanadium and at least 0.01% titanium for a total of at least 0.03%, preferably 0.05% to 0.15%, the balance zinc containing up to 1.3 wt. % lead. In another embodiment, the alloy comprises, by weight, aluminum in the amount of at least 0.001%, tin in the amount of 0.5% to 2%, and vanadium and nickel together in the amount of at least 0.02% vanadium and at least 0.02% nickel to a maximum of 0.15% vanadium and nickel collectively. Titanium may be added in an amount, by weight, of at least 0.01% titanium to a collective maximum of 0.

  • Patent number: 4386051
    Abstract: A method for soldering aluminum or aluminum alloys is disclosed, together with an alloy useful in the method. The method includes heating, for example by using a torch, at least one aluminum piece to a temperature within the range of 90-150 degrees celsius, cleaning at least one heated surface thereof, for example by wire brushing, further heating the cleaned piece to a temperature within the range of 350-490 degrees celsius, and applying, for example by rub soldering, to the cleaned and further-heated piece a quantity sufficient to enable subsequent soldering, as required, of a tin/lead/zinc alloy consisting essentially of, by weight, from 1.7 to 2.2 percent aluminum, from 0.01 to 0.02 percent magnesium, from 45.9 to 50.4 percent zinc, from 14.2 to 34 percent tin, and from 16.6 to 36.7 percent lead.
