Definitions
- the invention relates to the use of a silver-iron material with further additives for electrical contacts.
- the essential requirements for an electrical contact material are high erosion resistance, low welding force and low contact resistance.
- For air-tight switching devices in low-voltage technology e.g. Ag / SnO2 is particularly good for switching currents of 100 - 3000 A due to its high erosion resistance and protection against welding.
- For lower loads e.g. the composite material Ag / Ni has proven itself. Compared to fine silver, it has an increased erosion resistance without causing a significant increase in contact resistance.
- Another frequently used composite material is Ag / W, which is characterized by its high resistance to erosion. With frequent switching in air, however, a cover layer of silver tungstate forms, which leads to an increase in the contact resistance.
- the object is achieved according to the invention by using a silver-iron material with 3 to 30% by weight of iron and one or more of the following additives: manganese, copper, zinc, antimony, bismuth oxide, molybdenum oxide, tungsten oxide, chromium nitride in a total amount of 0. 05 to 5 wt .-% dissolved.
- These materials surprisingly achieve a reduction in the contact resistance and thus the contact heating, without the inherently good security against welding being impaired.
- the improvement in contact heating is up to 43% compared to Ag / Fe-90/10.
- the improvement is achieved by favorably influencing the formation of the Fe oxide layers that form. While the material Ag / Fe-90/10 has a continuous oxide layer without additives, this oxide layer is influenced by the additives mentioned in such a way that there is a low contact resistance combined with good security against welding.
- a material with 3 - 20% Fe and one or more of the additives Mn, Cu, Zn, Bi, Bi2O3, MoO3, WO3 and / or CrN in a total amount of 0.2 to 2% by weight is particularly suitable. It has also proven useful to add to the silver, in addition to 3 to 20% by weight of iron, either 0.2 to 2% only of metallic additives or 0.2 to 2% of only non-metallic additives.
- materials that, in addition to 3 to 20% iron, 0.2 to 2%, contain only one of the additives manganese, copper, zinc, antimony, bismuth oxide, molybdenum oxide or tungsten oxide, the rest silver.
- they preferably contain 0.2 to 2% zinc and optionally 0 to 2% copper, tantalum and / or antimony, the rest silver or 0.2 to 2% molybdenum oxide, the rest silver.
