Description

Niniejszy wynalazek dotyczy stopu, któ¬ rego glównym skladnikiem jest olów i któ¬ ry nadaje sie wszedzie tam, gdzie od stopu wymaga sie twardosci, ciagliwosci, malego oporu tarcia, odpornosci na dzialanie po¬ wietrza i latwej topliwosci, a wiec np. do wyrobu pamewek, zamiast metalu bialego i bronzu, do wyrobu kul strzelniczych, plyt akumulatorowych, czcionek, pokrycia ka- blów, a takze do lutowania i innych celów.Wynalazek polega na tern, ze do olowiu dodaje sie bar, w ilosci nie przekraczajacej 10%. Dla polepszenia wlasnosci takiego stopu olowiu i baru, ze wzgledu na topli¬ wosc, lejnosc, ciagliwosc i t. d., dodaje sie jeszcze jeden lub kilka lekkich metali jak wapn, stront 1 sód, przyczem zawartosc tych dodatkowych skladników razem nie powinna równiez przekraczac 10% .Stosowanie dodaitku lekkich metali do olowiu miekkiego i1 twardego, to znaczy o- trzymanego przez dodamie np. antymonu lub cyny, jest znane, lecz w niniejszym wynalalzku stosuje sie te dodatki1 do twar¬ dego olowiu, powstalego przez dodanie ba¬ ru, który mozna w mniejszej lub wiekszej czesci zastapic wspomnianeimi metalami lekkiemi, aby wplynac na zmiane pewnych wlasnosci nowego stopu.Takie stopy olowiu i baru z dodatkiem lub bez domieszki metali lekkich, sa tward¬ sze od stopów z taka satma zawartoscia wap- niaj i maja w porównaniu ze stopami zawie¬ rajacemi walpien te zalete, ze sa odpornfej-£ JO* szc iii, (izi^tól& atftiosferyczne, twardziej ciagliwe i mniej sklonne do wydzielMii& skladników.Przyklad 1.

PLThe present invention relates to an alloy whose main component is lead and which is suitable wherever hardness, ductility, low frictional resistance, air resistance and easy fusibility are required of an alloy, e.g. pellets, instead of white metal and bronze, for the manufacture of bullets, battery plates, fonts, cable coating, as well as for soldering and other purposes. The invention consists in adding a bar to the lead, in an amount not exceeding 10%. In order to improve the properties of such an alloy of lead and barium, one or more light metals such as calcium, strontium and sodium are added for reasons of meltability, castability, ductility, etc., while the content of these additional components together should also not exceed 10%. It is known to use a light metal additive to soft and hard lead, that is to say, made by the addition of, for example, antimony or tin, but the present invention uses these additives for hard lead formed by the addition of a bar which can be replace a greater or lesser part with the mentioned light metals in order to change some properties of the new alloy. These lead and barium alloys, with or without light metals, are harder than alloys with such a satma calcium content and have, compared to alloys, They contain the advantage that they are resistant to the disease (and atphospheric, tougher and less prone to the secretion of components. Example 1. Produce io hp. alloys containing 2.3% barium, 0.8% barium, 1.7% barium, further alloys containing 0.75 bar + 0.1% calcium, or 1.05% barium + 1.66% calcium. All the alloys were charasktel-lead and were completely air-resistant ^ Example 2. Feet that had grown 6% of Barium was allowed to be cast into sticks of 2 mm in diameter and nif * # alleviated the effects of the weather during ^ \ v | glu months. Alloys containing S%% of Barium had similar properties and was more resistant to weathering than an alloy with 3% calcium. Example 3 Alloys containing 2.05% barium, 0.8% calcium and 0.25% sodium, tested for strength , showed: 820 kg / cm2 at the liquid limit, 2270 kg / cm2 tear strength, and 28 kg Brineir hardness. At the same time, a normal white metal (70% tin) was tested, which showed the same liquidity limits, but its resistance to the tearing was 400 kg less. The base alloys of the invention are therefore perfectly suited for the production of bearing bushings.

When using any jifcko alloys of theo-theo metals, or for other purposes, it must be ensured that the content of barium and other constituents does not exceed! 5%. Similar properties to lead and bairo alloys, also have lead and strontium alloys. The hardness of lead and strontium alloys is nSeco lower compared to lead and barium alloys, but higher than lead and calcium alloys. Of course, lead and strontium alloys may also contain other light metals, and also contain 10% or more. according to the present invention. PL
