CMC Alloy Process - Ultrasonic Welding

CMC alloy process(copper molybdenum copper alloy) - ultrasonic welding as follow:

Ultrasonic welding is a solid-phase soldering method. In the static pressure, the longitudinal ultrasonic vibration in a periodic force on the composite metal laminates to be ALMT Japanese company Mo / Cu rolled into a strip, with its CMC alloy as an intermediate layer were prepared using a hot CMC alloy flat composite electronic packaging materials. As Mo / Cu Cu material was filled in between the molybdenum skeleton-like distribution network, making the product in a planar direction and a thickness direction of the same electrical and thermal conductivity than the alloy layer thickness ratio of CMC better.


And the middle of Mo-Cu alloy layer due to copper added, showing more excellent processing performance. Plansee, Austria produced Cu/Mo-30Cu/Cu (1:4:1) 3 layered composite material had a density of 9.5g/cm3, the planar direction of the thermal conductivity ≥ 260W /m·K, the thermal expansion coefficient of 8.0 × 10-6 ~ 10. 0 × 10-6/K, these properties are listed in table 1, even better than the layer thickness ratio of 1:2:1 alloy material superior CMC.

Rolling cladding technology and equipment is more mature, high yield, greatly reduce production costs, but also easy to implement large-scale industrial production, is a great potential for development of composite material technology. But rolling composite one-time investment, it is not conducive to small batch production.
