Definitions
- the invention relates to a copper alloy, in particular a lead and tellur990 copper alloy, as well as semi-finished products of such a copper alloy.
- copper Due to its natural qualities, copper is an indispensable material in many areas of industry and technology. Particularly where materials of the highest electrical and thermal conductivity are required, copper and copper alloys are of great importance. However, the use of pure copper is difficult then if parts are to be machined. The high toughness of copper, which is particularly valued in chipless shaping, proves to be a disadvantageous material property here. Essential for this is the long chip formation, which inhibits the workflow during drilling and turning and leads to heavy wear of the tool cutting. On CNC-controlled, but also on conventional automatic lathes, pure copper can normally only be processed or processed with uneconomically high expenditure of time, personnel and tools.
- lead and bismuth act in metallic form, while sulfur and tellurium act as intermetallic phase in the form of copper sulfide ⁇ CU 2 S) or copper telluride (Cu 2 e).
- copper sulfide ⁇ CU 2 S copper sulfide
- Cu 2 e copper telluride
- the low melting points of lead and bismuth limit hot workability, e.g. B. by extrusion, considerably, so that an economic processability on conventional manufacturing facilities not, or is given only limited.
- the invention is therefore based on the prior art, based on the object to show a copper alloy, which has at least the same or better machinability and cold and hot workability over the known copper alloys CuTeP and CuSP.
- a first solution to this problem is according to the invention in a copper alloy according to claim 1.
- a copper alloy based on copper with additions of manganese and sulfur as well as accompanying elements which does not require lead or tellurium but has good machinability is proposed.
- the copper alloy is made of copper containing, as alloying components, 0.05 to 0.80 wt.% Manganese (Mn), 0.10 to 0.80 wt.% Sulfur (S), optionally one or more elements derived from Selected from the group consisting of 0.002 to 0.05% by weight of phosphorus (P), 0.01 to 0.5% by weight of chromium (Cr), 0.01 to 0.5% by weight of aluminum (Al ), 0.01 to 0.5% by weight of magnesium (Mg), together with unavoidable impurities.
- Mn Manganese
- S S
- P phosphorus
- Cr chromium
- Al aluminum
- Mg magnesium
- the chip breaker in the CuSMn alloy according to the invention is a mixed phase consisting of copper suicide (Cu 2 S) and manganese sulfide (MnS).
- the manganese content is particularly preferably 0.10 to 0.20% by weight. Also preferred is a sulfur content which is between 0.20 to 0.60 wt .-%.
- a copper-based alloy according to claim 4. It consists of 0.30 to 1.50% by weight of calcium (Ca), optionally one or more elements selected from the group consisting of 0.005 to 0.05% by weight of manganese (Mn), 0.005 to 0.05% by weight of sulfur (S), 0.002 to 0.05% by weight of phosphorus (P), 0.01 to 0.5% by weight of chromium (Cr), 0.01 to 0.5% by weight % Of aluminum (AI), 0.01 to 0.5% by weight of magnesium (Mg) and the remainder copper (Cu) and unavoidable impurities.
- Ca calcium
- Mn manganese
- S sulfur
- P 0.002 to 0.05% by weight of phosphorus
- Cr chromium
- AI 0.01 to 0.5% by weight of aluminum
- Mg magnesium
- Cu copper
- the calcium content in the aforementioned copper alloy is between 0.5 to 1, 0 wt .-%.
- Phosphorus serves as a deoxidizer, which binds to the dissolved in the melt free oxygen and thus prevents gas bubbles (hydrogen disease) and oxidation of alloying constituents. Furthermore, phosphorus is added to improve the flow properties of the copper alloy during casting. Manganese refines the grain and improves its machinability in combination with sulfur.
- Aluminum increases hardness and mating limit without reducing toughness.
- Aluminum is an element that improves strength, machinability, and wear resistance as well as oxidation resistance at high temperatures.
- Chromium and magnesium are used to improve the oxidation resistance at high temperatures. Particularly good results are achieved when mixed with aluminum to achieve a synergistic effect.
- the inventively proposed two copper materials CuSMn and CuCa have a machinability that is equal to or better than CuSP.
- a machinability index of 90% for CuSMn, 86% for CuCa and 76 and 79% for the reference materials CuTeP and CuSP was determined.
- the materials have an electrical conductivity of between 35 to 55 MS / m, in particular in a range of 48 to 53 MS / m.
- inventively proposed copper alloys are free of toxic alloying elements and cost, since the alloying elements are available at low cost. It should also be emphasized that the scraps are reusable.
- a particular criterion of the two proposed copper alloys is that a processability with conventional manufacturing and processing machines is possible, in particular, the alloys have both a sufficient cold workability and a very good hot workability.
- CuSMn, CuCa and the reference materials CuTeP and CuSP were melted in a crucible induction furnace and cast into billets in the continuous casting process.
- the composition of the materials is shown in Table 1.
- the composition of CuSMn complies with claims 1, 2 and 3
- CuCa complies with claims 4 and 5.
- the composition of the reference materials meets the requirements of the EN and ASTM standards for the materials CuTeP and CuSP.
- the extruded round bolts were extruded without problems to press rods in an extrusion process with a heating temperature> 850 ° C and then pulled with a cross-sectional decrease of 10 to 15% to the final dimension of ⁇ j> 35 mm.
- Comparative machinability tests were performed in the form of drilling tests on the bars listed in Table 2. Preference has been given to machining by drilling, because the production of small holes (e.g., in burner nozzles) is the most difficult machining shape. If a material shows positive results here, turning or tapping is no problem either.
- Drilling tool 2 mm ⁇ solid carbide drill with internal cooling
- Drilling strategy Introduce 45 holes into rod sections at the front:
- the individual ratings have been added, with a maximum of 80 points are achievable.
- This overall assessment of machinability should be defined here as a machinability index, with 80 points corresponding to a maximum achievable machinability index of 100%.
- the new materials CuCa and CuSMn according to the invention achieve the following machinability indices in comparison to the reference materials:
- the alloying elements aluminum (AI), calcium (Ca), cobalt (Co), chromium (Cr), iron (Fe), magnesium (Mg), manganese (Mn), molybdenum (Mo), nickel (Ni) were investigated in each case.
- the proven materials CuSP and CuTeP served as comparison samples for the machinability tests. Qualitatively, the chip shape was measured when drilling 3 mm holes and the occurrence of drill breaks.
- the desired material properties or property combinations were achieved by the addition of manganese, to a proportion of 0.05 to 0.80 wt .-%, preferably 0.10 to 0.30 wt .-%, in particular 0.10 to 0.20% by weight and sulfur in a proportion of 0.10 to 0.80% by weight, in particular 0.20 to 0.60% by weight.
- the desired material properties are achieved with a copper-based alloy containing calcium as the alloying constituent in a proportion of 0.30 to 1.50% by weight, preferably between 0.5 and 1.0% by weight. contains%.
- the two copper materials CuSMn and CuCa shown have the aforementioned independent chip-breaking phases, namely the mixed phase comprising Cu 2 S and MnS or the electropatic phase CusCa.
- the copper alloy CuSMn has a CuTeP-comparable or even slightly better hot and cold formability with the copper alloy CuSP or the copper alloy.
- composition of the materials according to the invention CuSMn, CuCa and the reference materials CuTeP and CuSP
