Definitions
- the invention relates to a material for a metal band for the production of electricalnapsbauteiten according to the Merkmaien in the preamble of claim 1 and the use of such a material for an electrically conductive Metailband for the production of electrical contact components according to the features of claim 8.
- Contact components find a variety of applications in the field of electrical engineering and electronics. As mechanically interconnectable and separable fasteners whose main task is to produce an electrically conductive contact, in addition to the closing of circuits as well as direct couplings with electronic components can be realized.
- the respective design is based both on country-specific standards and on the requirements to be met in the area of application, In particular, in the form of hand-releasable electrical plug contacts thus increased demands are placed on their mechanical strength.
- High-quality plug contacts have a stable contact resistance, in which the preservation of the low contact resistance is in the foreground.
- a change in the contact resistance is usually due to the electrical breakdown of corrosion or foreign layers.
- Kontakfbaumaschine these often have a tin or chrome coating up to a silver or gold coating.
- JP 20G8 / 2 ⁇ S488 A a copper alloy for plug contacts is known, which has a zinc content (Zn) in wt .-% of 23% to 28%. Other constituents are represented by at least 0.01%, with silicon (Si) reaching a maximum of 3% while nickel (Ni) accounts for up to 5%.
- JP 2009/013499 A also discloses a copper material for plug contacts with a proportion of zinc (Zn) in wt .-% of 20% to 41%. The proportion of nickel (Ni) ranges from 0.1% to 5.0%, the Zinnanteii (Sn) is from 0.5% to 5.0%.
- DE 103 08 779 B3 shows a lead-free copper alloy and their use. Their constituents in wt .-% are for copper (Cu) at least 80% to a maximum of 70% and thus quite high. On the other hand, a content of nickel (Ni) of 0.01% to 0.5% is proposed, while the content of tin (Sn) is from 0.5% to 3.5%. A possible proportion of silicon (Si) may range from 0.01% to 0.5%.
- the high proportion of copper entails rather high purchase prices for the base material.
- the shares of the other alloying partners in terms of improved material properties still offer room for improvement.
- the present invention is therefore based on the object to improve a material for a metal strip for the production of electrical contact components in such a way that it meets the necessary properties for use for an electrically conductive material for the production of electrical contact components despite cost-effective shares of its individual alloying partners.
- a material for a metal strip for the production of electrical contact components, in particular of plug contacts proposed, consisting of a curable alloy with proportions in wt .-% of
- Zinc (Zn) from 19.0% to 40.0%
- Tin (Sn) from 0.1% to 1, 5%
- Nickel (Ni) from 0.6% to 3.0% and Silicon (Si) from 0.1% to 0.9% ..
- the material may optionally comprise at least one element from the following group:
- the remainder of the material is formed from copper (Cu) and impurities caused by melting. Furthermore, the proportion of Ni (Ni) may be at least partially replaced by cobalt (Co). Thus, nickel (Ni) may also be 100% and thus completely replaced by cobalt (Co). The ratio of the proportions of nickel (Ni) and / or cobalt (Co) to the element silicon (Si) ranges from 3.5: 1 to 7.5: 1.
- the etallband for the production of electrical contact components consists of the hardening alloy CuZn30Sn1 i1SiO ; Second
- the particular advantage lies not only in the high content of zinc (Zn) and the associated favorable production price in the increased strength of the material. Compared with copper, the increased strength is due to the formation of crystals of ivicite. The solidification achieved in this way is one of the possible strength-increasing processes in order to obtain a hard material from an otherwise relatively soft metal.
- the precipitation hardening with nickel (Ni) - SiHziden can achieve a significantly higher strength with good elongation and thus increased bendability. This is especially true in comparison with pure mixed-crystal-strengthened and cold-strengthened special brasses, such as, for example, CuZn25Sn1. This is also possible in high strength conditions such as B. at R780 (R m 780 IvlPa) still achieve an elongation at break ⁇ 5 o of> 3% (DIN 50125). The relaxation resistance is significantly better than that of CuSn4 and CuZn25Snl
- Zinc (Zn) from 25.0% to 33.0%
- Tin (Sn) from 0.5% to 1, 2% as well
- Nickel from 0.8% to 2.5%
- Zinc (Zn) from 27.0% to 31.0%
- Tin (Sn) from 0.5% to 1.2% as well
- Nickel from 0.8% to 2.0% and
- Silicon (Si) from 0, 1% to 0.6%.
- Ni nickel
- Co Co
- a ratio of nickel (Ni) and / or cobalt (Co) to silicon (Si) should be maintained from 3.5: 1 to 7.5: 1. Preferably, this ratio may be from 4.0: 1 to 5.0: 1.
- Phosphorus (P) from 0.001% to 0.05%
- Boron (B) from 0.02% to 0.5%
- Silver (Ag) from 0.02% to 0.5%
- Chromium (Cr) from 0.01% to 0.7%
- Magnesium (Mg) from 0.01% to 0.4%
- Iron (Fe) from 0.01% to 0.8% as well
- Arsenic (As) from 0.001% to 0.1%.
- the elements contained in the group may optionally be present in the present material.
- phosphorus (P) and / or boron (B) can be added in the stated amount, serving as a deoxidizer. Their presence causes the free oxygen (O) dissolved in the melt to become bound. In this way, the hydrogen disease is counteracted by preventing the formation of gas bubbles as well as oxidations of alloying constituents.
- phosphorus (P) serves to improve the fi lling properties of the present copper alloy during casting.
- manganese (Mn) When manganese (Mn) is added, its solidifying property on the copper alloy is primarily used. At the same time, manganese (n) also serves as a deoxidizer.
- the addition of aluminum (AI) increases the hardness of the material and its yield strength. The said positive increases go thereby without reducing the toughness of the material. Overall, the addition of aluminum (AI) serves to improve the strength, machinability, and wear resistance and oxidation resistance of the alloy at high temperatures.
- chromium (Cr) and magnesium (Mg) serves to improve the oxidation resistance at high temperatures. This can be better Results are achieved by mixing chromium (Cr) and magnesium (Mg) with aluminum (Al),
- zirconium improves the hot workability of the material.
- the invention shows a use of the copper material for an electrically conductive metal strip.
- the metal strip is used for the production of electrical contact components, in particular of plug contacts.
- the metaflband used in this way can be tinned on the surface.
- the metal strip used may comprise a tin-silver layer (SnAg).
