Flux melting subduction zone
WebIn modern subduction zones, subduction rates vary by a factor of 30, and average ages of the slab vary from 5 Ma to 145 Ma, yet no correlation is … WebA good flux helps the solder alloy flow on the metal surface. Just as the flux itself spreads onto the surface, the solder alloy must also. A good flux will lower the surface tension …
