Definitions
- the invention relates to a copper-nickel-zinc alloy, in which ⁇ - and ⁇ -phase structure consisting of nickel, iron and manganese and / or nickel, cobalt and manganese mixed silicides are incorporated as spherical or ellipsoidal particles, and the use of such a copper-nickel-zinc alloy.
- Alloys of copper, nickel and zinc are called nickel silver because of their silver-like colors. Commonly used alloys have between 47 and 64% by weight of copper and between 7 and 25% by weight of nickel. In turnable and drillable alloys usually lead up to 3 wt .-% lead are added as a chip breaker, in cast alloys even up to 9 wt .-%. The rest is zinc. As admixtures commercial nickel silver alloys may also contain 0.2 to 0.7 wt .-% manganese to reduce the Glühbrüchmaschine. Also, the manganese additive acts deoxidizing and desulfurizing.
- Nickel-silver alloys such as CuNi12Zn24 or CuNi18Zn20, are used in the optical industry, among others, for the manufacture of spectacle hinges.
- the progressive miniaturization of these products requires materials with higher strength.
- these products have high demands on the quality of the surface.
- Nickel silver alloys are also used to make jewelery and watch parts. These products are particularly demanding on the Quality of the surface.
- Even when pulled, the material must have a glossy and polished surface that is free from defects such as grooves or voids.
- the material must be very easy to machine and, if necessary, also be polishable.
- the color of the material must not change during use. Very similar requirements apply to materials used in medical technology or for the production of musical instruments.
- the publication JP 01177327 describes easily machinable nickel silver alloys with good hot and cold workability. These alloys consist of 6 to 15% Ni, 3 to 8% Mn, 0.1 to 2.5% Pb, 31 to 47% Zn, balance Cu with unavoidable impurities. Optionally, small amounts of Fe, Co, B, Si or P may be added to prevent grain growth on warming prior to hot working.
- the invention has for its object to provide a copper-nickel-zinc alloy with improved surface quality with high strength.
- the surface should already look like polished when pulled.
- the alloy should have a good machinability and excellent color fastness.
- the invention has for its object to provide a use for such a copper-nickel-zinc alloy.
- the invention includes a copper-nickel-zinc alloy having the following composition in% by weight: Cu 46.0 to 51.0%, Ni 8.0 to 11.0%, Mn 0.2 to 0.6%, Si 0.05 to 0.5%, Fe and / or Co each up to 0.8%, wherein the sum of Fe content and twice the Co content is at least 0.1 wt .-%, Residual Zn as well as unavoidable impurities, wherein in a microstructure consisting of ⁇ - and ⁇ -phase nickel-, iron- and manganese-containing and / or nickel, cobalt and manganese mixed silicides are incorporated as spherical or ellipsoidal particles.
- the invention is based on the consideration that the structure of nickel silver materials by alloying of silicon is varied so that silicide precipitates are formed.
- Silicides as intermetallic compounds have about 800 HV significantly higher hardness than the ⁇ and ⁇ phase of the matrix structure.
- manganese is added to improve the cold and hot forming capacity and to increase the strength.
- manganese acts deoxidizing and desulfurizing.
- silicon forms mixed silicides of approximate composition predominantly between (Mn, Fe, Ni) 2 Si and (Mn, Fe, Ni) 3 Si.
- mixed silicides of approximate composition (Mn, Co, Ni) x Si y , where x ⁇ y.
- mixed silicides can be formed which contain both iron and cobalt in addition to manganese and nickel.
- the mixed silicides are finely distributed as spherical or ellipsoidal particles in the matrix structure. The mean value of the volume-equivalent diameter of the particles is 0.5 to 2 ⁇ m.
- the microstructure does not contain large-scale silicides, which therefore easily break out of the matrix structure. This advantageous property is achieved in the alloy according to the invention in particular by the low levels of manganese and iron or cobalt.
- Both iron and cobalt act as nucleation sites for silicide formation, ie in the presence of iron and / or cobalt even small deviations from the thermodynamic equilibrium are sufficient, so that small precipitates are formed.
- These precipitation nuclei which may also contain nickel in the present alloy composition, are finely distributed in the microstructure. They are further silicides, which now also contain manganese, preferably on. The low manganese content of the alloy limits the size of the individual silicides. Small amounts of iron and / or cobalt in Combination with a small amount of manganese are therefore the prerequisite for the formation of mixed silicides.
- the minimum amount of iron or cobalt is defined by the fact that the sum of the iron content and twice the cobalt content is at least 0.1 wt .-%.
- the copper-nickel-zinc alloy according to the invention has an excellent surface quality. Even when pulled, the surface of the material is very smooth, silvery shiny and free of visible defects. The surface looks like it's already polished. Thus, the surface of a semi-finished product produced by a forming process, such as a drawing or rolling process from an alloy according to the invention in many cases already meets the quality requirements of the final product. Further processing to improve the surface is no longer necessary.
- the average roughness Ra of the surface of such a semifinished product is typically at most 0.2 ⁇ m. The average roughness Ra is determined over a measuring length of at least 4 mm.
- the surface quality of the copper-nickel-zinc alloy according to the invention is at least as good as the materials previously used in the optics industry.
- the strength of the copper-nickel-zinc alloy according to the invention is significantly higher than that of the materials used hitherto. This increase in strength allows the components to be made smaller and more filigree and thus meet the current design requirements.
- the tensile strength of the copper-nickel-zinc alloy according to the invention is between 700 and 900 MPa, depending on the degree of deformation of the material. In the hard state, it is at least 800 MPa.
- Workpieces made of a copper-nickel-zinc alloy according to the invention are characterized by a very high-quality surface and an attractive appearance, so that this alloy for the production of jewelry and watch parts are suitable. Furthermore, workpieces of a copper-nickel-zinc alloy according to the invention can be polished very well, whereby the visual impression of the workpiece can be further improved if necessary and the value of the product can be increased. Furthermore, the surface of the copper-nickel-zinc alloy according to the invention is readily coatable because of its excellent flatness.
- the surface quality of a copper-nickel-zinc alloy according to the invention is significantly better than that of lead-containing copper-nickel-zinc alloys of similar composition.
- a copper-nickel-zinc alloy according to the invention small amounts of lead of up to 0.1 wt .-% may be contained in the impurities, which are neither matrix effective nor have an influence on the formation of Mischsilicide.
- the lead content of a copper-nickel-zinc alloy according to the invention is preferably at most 0.05% by weight.
- a copper-nickel-zinc alloy according to the invention is particularly preferably lead-free.
- Another advantage of a copper-nickel-zinc alloy according to the invention is its high zinc content of about 40 wt .-%. This makes the material cheaper than, for example, the nickel silver alloys CuNi12Zn24 or CuNi18Zn20.
- a copper-nickel-zinc alloy according to the invention has a good machinability.
- the alloy can be well formed both warm and cold. The production costs of semi-finished products and end products are thereby reduced.
- the copper-nickel-zinc alloy according to the invention has a very good machinability, although it contains at most very small amounts of lead. Even at Pb levels well below the threshold of unavoidable impurities, a copper-nickel-zinc alloy of the invention is readily machinable.
- the reasons for the good machinability of the alloy are the finely divided mixed silicides, which act as chip breakers.
- either the Fe content or the Co content can be at least 0.1% by weight. This favors the formation of finely divided mixed silicides.
- the copper-nickel-zinc alloy according to the invention may have the following composition [in% by weight]: Cu 47.5 to 49.5%, Ni 8.0 to 10.0%, Mn 0.2 to 0.6%, Si 0.05 to 0.4%, Fe 0.2 to 0.8%, optionally up to 0.8% Co, Rest Zn as well as unavoidable impurities.
- nickel-, iron- and manganese-containing mixed silicides may be incorporated as spherical or ellipsoidal particles in an ⁇ - and ⁇ -phase microstructure.
- the selective alloying of iron produces very fine mixed silicides which have an advantageous effect on the surface quality of the material.
- the copper-nickel-zinc alloy according to the invention may have the following composition [in% by weight]: Cu 47.5 to 49.5%, Ni 8.0 to 10.0%, Mn 0.2 to 0.6%, Si 0.05 to 0.4%, Co 0.1 to 0.8%, optionally up to 0.8% Fe, Rest Zn as well as unavoidable impurities.
- nickel-, cobalt- and manganese-containing mixed silicides may be incorporated as spherical or ellipsoidal particles in a microstructure consisting of ⁇ - and ⁇ -phase.
- the deliberate alloying of cobalt produces mixed silicides which have an advantageous effect on the strength of the material with at the same time good surface quality.
- a further aspect of the invention includes the use of an alloy according to the invention for the production of consumer goods with high demands on the surface quality such as jewelry, watch parts, eyeglass hinges, musical instruments or devices for medical technology. Due to the excellent surface quality of workpieces made of an alloy according to the invention, this is particularly suitable for the production of jewelry, watch parts and musical instruments. Also advantageous in these applications is the high color stability of the alloy. The color fastness follows from the high corrosion resistance of the alloy. Devices used in medical technology must be easy to clean. The smoother the surface of the devices, the easier it is to remove unwanted substances. The combination of good surface quality and high strength predestines the copper-nickel-zinc alloy according to the invention for the production of spectacle hinges.
- Another aspect of the invention involves the use of an alloy according to the invention for the production of keys, locks, connectors or lead tips for ballpoint pens.
- the advantageous properties of a copper-nickel-zinc alloy according to the invention with respect to workability, namely good formability and good machinability come into play.
- the good corrosion resistance of the copper-nickel-zinc alloy according to the invention has an advantageous effect.
- a copper-nickel-zinc alloy according to the invention and three comparative alloys were melted and poured into bolts. From the bolts, wires and rods with an outer diameter of 4 mm were produced by means of hot pressing and cold forming.
- Table 1 shows the composition of the individual alloys in% by weight.
