This contact is characterized by its diagonal-wound spring shape. In addition to beryllium copper, which is commonly used for electrical contact materials, materials such as stainless steel, Inconel, and Hastelloy can also be selected, enabling the production of large-current and high-current connectors suitable for environmental conditions (high temperature and corrosion).
| Material | Temperature (℃) | Conductivity % (IASC) | Selection Guidelines |
|---|---|---|---|
| BeCu Alloy 25 | -273～180 | 14 | ～180℃ |
| SUS302 | -273～370 | 2.3 | General |
| SUS316 | -273～340 | 2.3 | Corrosion resistant |
| Titanium Grade 2 | -273～315 | 1 | High temperature & corrosion resistant |
| Hastelloy C-276 | -57～480 | 1.4 | High temperature & corrosion resistant |
| Inconel X-750 | -57～680 | 1.4 | High temperature |
The available shapes for production range from long reel-wound products, which are convenient for manufacturing RF shields and large flat high-current connectors, to donut shapes (with inner diameters ranging from a few millimeters to around 500 millimeters) that match the sizes of various large-current and high-current connectors. Additionally, various surface treatments like those applied to our large-current and high-current contact bands can also be applied.
