Copper-magnesium wire FAQ: Frequently asked questions about our CuMg alloys
What are the special features of the copper-magnesium based materials SD01, SD02, SD03, SD04 and SD05?
Magnesium increases the strength of the copper and reduces the conductivity relatively slightly. By adding Mg in the range of 0.1 to 0.8 % Mg, the ratio of tensile strength and conductivity can be adjusted very precisely.
CuMg is suitable for electrical connections, for connector pins, conducting wire and for overhead telephone lines.
In recent years, CuMg has gained more and more importance as a material for contact wires and suspension cables for high-speed trains.
The CuMg family of alloys is used as a substitute for copper cadmium, which is already banned in many countries because of its toxic properties.
What are the special features of the copper-magnesium based material SF02?
Wires made of the copper-magnesium alloy SF02 belong to the low-alloyed copper materials that are characterised by very good electrical conductivity and excellent mechanical properties.
Compared to copper, SF02 in the work-hardened state is characterised by significantly higher strength, much better softening properties and excellent behaviour under reverse bending loads. SF02 offers good cold formability and deep drawability.
Due to its physical properties, this wire metal is predestined to be used in automotive wiring systems, e.g. with regard to miniaturised cross-sections of wire harnesses. SF02 does not contain cadmium. Like many other copper alloys produced by Sundwiger Messingwerk, SF02 belongs to the “green alloys” and can be recycled without any problems.
