Description

Przedmiotem wynalazku jest stop miedzi o wysokiej odpornosci korozyjnej oraz odpornosci na scieranie, o bardzo dobrej podatnosci do przeróbki plastycznej na goraco i na zimno, przeznaczony zwlaszcza do wykony¬ wania monet, medali oraz galanterii metalowej. Stop wedlug wynalazku zblizony jest swym skladem chemicz¬ nym do znanego z polskiej normy PN-77/H-87025 oraz radzieckiej normy GOST 15527-70, zawierajacego wago¬ wo: 64,0-67,0% Cu, 5,0-6,5% Ni, reszte stanowi cynk.Znany jest takze z radzieckiej normy GOST 15527-70 stop LANK Mc 75-2-2,5-0,5-0,5 zawierajacy wago¬ wo: 73-76% Cu, 2-3% Ni, 0,3-0,7% Mn, 1,6-2,2% Al, 0,3-0,7% Si, reszte stanowi Zn. Zgodnie z wynalazkiem, stop miedzi, charakteryzuje sie tym, ze zawiera wagowo: 29-31% cynku, 4,5-5,5% niklu, 0,05-1,0% manganu, reszte stanowi miedz.Sklad chemiczny stopu wedlug wynalazku pozwala uzyskac stop o kolorze zlocisto-zóltym, o lepszej odpornosci na scieranie i na korozje od znanych stopów przy jednoczesnie bardzo dobrej odksztalcalnosci na goraco i na zimno oraz wysokiej odpornosci na tworzenie brudzacych, nieestetycznych nalotów. Stop wedlug wynalazku moze byc produkowany zarówno sposobem konwencjonalnym przez topienie w piecach indukcyj¬ nych i odlewanie do wlewnic statycznych jak równiez z zastosowaniem odlewania pólciaglego lub ciaglego, w przeciwienstwie do znanych stopów, które mozna odlewac tylko sposobem konwencjonalnym.Ponizej podano przyklad stopu wedlug wynalazku. Stop miedzi zawiera wagowo: 0,3% Mn, 5% Ni, 30% Zn, reszte stanowi Cu. Twardosc stopu w stanie zrekrystalizowanym wynosi 80 HB. Otrzymany stop nadaje sie do przeróbki w automatycznych prasach kuzniczych nie powodujac przedwczesnego zuzycia narzedzi, ponadto zachowuje przez dlugi okres czasu estetyczny, pozbawiony brudzacego nalotu wyglad.Zastrzezenie patentowe Stop miedzi zawierajacy miedz, cynk, nikiel i mangan, znamienny tym, ze zawiera wagowo: 29-31% cynku, 4,5-5,5% niklu, 0,05-1,0% manganu, reszte stanowi miedz. PLThe subject of the invention is a copper alloy with high corrosion resistance and abrasion resistance, with a very good hot and cold plastic working properties, intended especially for making coins, medals and metal accessories. According to the invention, the chemical composition of the alloy is similar to that known from the Polish standard PN-77 / H-87025 and the Soviet standard GOST 15527-70, containing by weight: 64.0-67.0% Cu, 5.0-6 5% Ni, the rest is zinc. Also known from the Soviet standard GOST 15527-70 LANK Mc 75-2-2.5-0.5-0.5 alloy containing by weight: 73-76% Cu, 2- 3% Ni, 0.3-0.7% Mn, 1.6-2.2% Al, 0.3-0.7% Si, the rest is Zn. According to the invention, the copper alloy is characterized in that it contains by weight: 29-31% zinc, 4.5-5.5% nickel, 0.05-1.0% manganese, the rest is copper. The chemical composition of the alloy according to the invention allows to obtain an alloy with a golden-yellow color, with better abrasion and corrosion resistance than known alloys, with a simultaneous very good hot and cold deformation and high resistance to the formation of dirty, unsightly raids. The alloy according to the invention may be produced by both the conventional method by melting in induction furnaces and casting into static ingot molds as well as by using semi-continuous or continuous casting, unlike the known alloys which can only be cast by conventional method. The following is an example of an alloy according to the invention. The copper alloy contains by weight: 0.3% Mn, 5% Ni, 30% Zn, the remainder being Cu. The hardness of the alloy in the recrystallized state is 80 HB. The obtained alloy is suitable for processing in automatic forging presses, without causing premature wear of the tools, and for a long period of time, it maintains an aesthetic appearance, free from staining tarnish. Patent claim A copper alloy containing copper, zinc, nickel and manganese, characterized by its weight: 29 -31% zinc, 4.5-5.5% nickel, 0.05-1.0% manganese, the rest is copper. PL
