All values should be regarded as typical, since these properties are dependent on the particular type of alloy, heat treatment, and other factors. the suitability of your design and the materials that you select. The properties of AZ91D magnesium include three common variations. Need an editable periodic table to edit? When magnesium is used as a deoxidizer, it helps to remove impurities in nickel-based alloys as well as gases that can negatively impact the melt. This metal is also considered a very soft material, as its malleability allows it to be worked into wires and cables. Automotive switches, relays, wire harnesses and cables are used in the electrical systems. It’s often used for electrical wiring purposes and electrical contacts for small and large applications. The addition of 0.1 to 0.7% magnesium to copper results in a cold workable solid solution strengthened alloy with good electrical conductivity.

Magnesium Removing Impurities and Adding Strength to Copper. The electrical conductivity and corrosion resistance in copper is enhanced by the magnesium. 2. Pure Magnesium: Thermal conductivity measures a materials ability to allow heat to pass through it via conductance. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Low-temperature electrical resistivity and thermal conductivity of binary magnesium alloys. The thermal conductivity values are calculated from electrical conductivity values. In addition, it has a moderately low electrical conductivity and a moderately low melting temperature. Copper with magnesium is commonly formed to create wires and cables for a wide range of industries. Applications include connectors, semiconductor, pins, stranded wire, contact parts for the lighting industry, contact elements, telecommuncation cables, (car) wire harnesses, flat wire, special screws, pressed parts, rivets, catenary trolley cables and conductors. 6. However, its strengthening effect is considerable. Embodied Carbon. for your casting suppliers. 22 kg CO 2 /kg material. Therefore, it is very suitable for the connection of electric components as well as for suspended cables. These may include test bars, chemical 3. Search for "Gelson Luz" in your favorite browser to learn more. Copper Magnesium has the highest tensile strength when compared to other alloys, making it the perfect alloy for contact wire in high speed lines with speeds well above 300 km/h. 1. values of this alloy. Practically resistant against stress corrosion cracking. The strengthening effect, however, is significant. Compared to copper, CuMg0,2 in cold work-hardened condition is characterized by significant higher strength, essentially better softening performance and outstanding behavior under reversed bending stresses. The reasons for large differences in the thermal conductivity of the three binary magnesium alloy systems are discussed. The low-temperature thermal conductivity was understood using κ = (A/T + BT2)−1 + CT2, which is found to be applicable in various binary and/or multi-component alloy systems. 7. Embodied Water. YOUR REVIEW, USE, OR POSSESSION OF THIS INFORMATION. You and you alone are responsible for Copper-magnesium is a solid solution alloy providing high strength with nominal reduction in conductivity relative to copper. M11916 is the UNS number. Resistant to atmospheric corrosion: formation of the a greenish protective patina due to the formation of copper basic salts (such sulphates, chlorides in marine environment, nitrates and carbonates). This Table gives typical values of thermal several common commercial metals and alloys. Before making a final decision on alloy selection consider The electrical conductivity and corrosion resistance in copper is enhanced by the magnesium. Atomic Mass 24,305 Learn more about the atomic mass. Thermal conductivity (k) 138 W/m*K: Linear thermal expansion coefficient (α) 2.38*10 −5 K −1: Specific heat capacity (c) 880 J/kg*K: Electrical properties; Volume resistivity (ρ) 49.3-49.9 nOhm*m: 5052 is an aluminium alloy, primarily alloyed with magnesium and chromium. Applications for Magnesium and Copper Alloys Most of the applications that have copper alloys with magnesium added focus on wire and cable features due to the conductivity and tensile strength of this alloy. Within the copper – magnesium - alloy - family, CuMg0,1 has the highest electrical conductivity. Alloying has a great effect on thermal conductivity. The growing use of electronic assistance systems constitutes a major step in this direction, which entails an increasing demand for signal cables. It is used to create telecommunication cables, conductor wires, and connector wires. While it cannot be used in welding applications, it can be used in soldering and brazing. Thus, the very good electrical conductivity of the material remains unaffected whilst its excellent mechanical strength persists. The magnesium helps to separate the impurities and bring them to the surface. 10 to 12 % IACS. The automotive industry heavily relies on copper and magnesium alloys when creating vehicles. This makes it a perfect fit for data cables and signal cables featuring very low diameters and cross-sections, but also a sufficient tensile strength. FOUNDRY (SPF) TO ENSURE ACCURACY, THIS INFORMATION IS PROVIDED FOR Catenary cables to provide lighting features also rely on copper and magnesium alloys.
