Description
Gjenstanden for BRD utlegningsskrift nr. I.962.76O er anvendelsen av en loddelegering, bestående av <*>l til 20% silicium og 0,01 til 10%, fortrinnsvis 0,05 til 2% av hvert av elementene wismut, strontium, barium og/eller antimon, resten aluminium og fremstillingsbetingede forurensninger, som loddemiddel til flussmiddelfri lodding av aluminiummaterialer i en ikke oksyderende atmos-fære resp. i et lavt vakuum. The object of BRD explanatory document no. I.962.760 is the use of a solder alloy, consisting of <*>1 to 20% silicon and 0.01 to 10%, preferably 0.05 to 2% of each of the elements bismuth, strontium, barium and/or antimony, the rest aluminum and manufacturing-related contaminants, as solder for flux-free soldering of aluminum materials in a non-oxidizing atmosphere or in a low vacuum.
Gjenstanden for BRD off. skrift nr. 2.1^3.965-6 The item for BRD off. writing No. 2.1^3.965-6
er et lodderniddel til f lussmiddelfri lodding av aluminiummaterialer, bestående av ^ til 20% silicium og 0,01 til 10%, fortrinnsvis 0,05 til 2% wismut, strontium, barium og/eller antimon, resten aluminium og fremstillingsbetingede forurensninger, hvis trekk består i at istedenfor eller sammen med wismut, strontium, barium og/eller antimon er det tilstede et innhold av beryllium i mengder fra 0,00001 - 1,0, fortrinnsvis 0,0002 - 0,1%. is a soldering iron for flux-free soldering of aluminum materials, consisting of ^ to 20% silicon and 0.01 to 10%, preferably 0.05 to 2% bismuth, strontium, barium and/or antimony, the rest aluminum and manufacturing-related impurities, whose features consists in that instead of or together with bismuth, strontium, barium and/or antimony, a content of beryllium is present in amounts from 0.00001 - 1.0, preferably 0.0002 - 0.1%.
Disse loddelegeringer har fått god innpass i praksis. These solder alloys have found good use in practice.
De stiller imidlertid ved lodning dessuten for-holdsvis store krav til nærvær av en ikke oksyderende atmosfære resp. et lavt vakuum. However, when soldering, they also make relatively high demands on the presence of a non-oxidizing atmosphere or a low vacuum.
Til grunn for oppfinnelsen ligger den oppgave å tilveiebringe loddelegeringer til lodding i en ikke oksyderende atmosfære resp. i et lavt vakuum, hvor det er mulig å nedsette nevnte krav. The invention is based on the task of providing soldering alloys for soldering in a non-oxidizing atmosphere or in a low vacuum, where it is possible to reduce said requirements.
Oppfinnelsens gjenstand er således anvendelse av The object of the invention is thus the application of
en loddelegering, bestående av H - 20% silicium og 0,01 til 10%, fortrinnsvis 0,05 til 2% av hvert av metallene wismut, strontium, barium og/eller antimon, eventuelt 0,00001 til 1,0, fortrinnsvis 0,0002 til 0,1% beryllium samt istedenfor eller fordelaktig sammen med disse elementer 0,0001 til 1%, fortrinnsvis 0,005 til 0,1% natrium, kalium og/eller litium, resten aluminium og frem- a solder alloy, consisting of H - 20% silicon and 0.01 to 10%, preferably 0.05 to 2% of each of the metals bismuth, strontium, barium and/or antimony, optionally 0.00001 to 1.0, preferably 0 .0002 to 0.1% beryllium and instead or advantageously together with these elements 0.0001 to 1%, preferably 0.005 to 0.1% sodium, potassium and/or lithium, the rest aluminum and
stillingsbetingede forurensninger som loddemiddel til flussmiddelfri lodding av aluminiummaterialer i en ikke oksyderende atmosfære resp. i et lavt vakuum. Forsøket har vist at ved anvendelse av disse loddemidler behøves det ikke mer å stilles så strenge krav som tidligere med hensyn til loddeatmosfærens oksygeninnhold resp. vakuumets høyde, mens det er oppnåelig like eller bedre resultater, som resp. som ifølge overnevnte søknader. position-related contaminants such as solder for flux-free soldering of aluminum materials in a non-oxidizing atmosphere or in a low vacuum. The experiment has shown that when using these solders, there is no longer any need to set as strict requirements as previously with regard to the oxygen content of the soldering atmosphere or the height of the vacuum, while equal or better results are achievable, as resp. as per the above applications.
Tilsetningen av alkalimetalier har vist seg spesielt gunstige.med hensyn til korrosjonsbestandighet av de loddede forbindelser, spesielt ved tilgang av fuktighet.. Dette gjelder i fremragende grad fremfor alt, når det foruten alkalimetall til loddemidlet dessuten settes beryllium. The addition of alkali metals has proven to be particularly beneficial with regard to the corrosion resistance of the soldered connections, especially when moisture is present.
Når man vurderer korrosjonsbestandigheten .med tall fra 0 til 5, idet med'0 er å forstå det tall som id»f>"H; resp. praktisk talt ikke er - oppnåelig, så er prøvene med tilsetning av. beryllium og alkalimetall å vurdere med 1, prøvene uten beryllium, me.n med alkalimetall med 2, og slike uten innhold av alkalimetall og beryllium med 3-When evaluating the corrosion resistance with a number from 0 to 5, with 0 being understood as the number that id»f>"H; or practically not - achievable, then the samples with the addition of beryllium and alkali metal are to be evaluated with 1, the samples without beryllium, i.e. with alkali metal with 2, and those without alkali metal and beryllium content with 3-
Det har vist seg hensiktsmessig å tilmåle den samlede mengde av legerlngselementene wismut, strontium, barium, antimon, beryllium og natrium til maksimalt 10%. It has proven appropriate to measure the total amount of the alloying elements bismuth, strontium, barium, antimony, beryllium and sodium to a maximum of 10%.
