Applications of Alumina Dispersion Strengthened Copper C15760:
Cuberyllium C15760(RWMA Class 20) is primarily designed for applications requiring the highest elevated temperature strength coupled with relatively high electrical and thermal conductivities. It exhibits a high degree of resistance to softening after exposure to elevated temperatures. Cuberyllium C15760 has sufficient cold working charateristics for heading, extrusion and some drawing and rolling operations.
| Recommended for: | Resistance welding electrodes |
| Welding electrodes |
| Solder gun tips and MIG contact tips |
For applications requiring brazed joints and /or extended high temperature exposure in hydrogen-containing atmospheres or vacuum, low Oxygen is availbale and recommended.
