Cast base-metal alloys are rarely used to make full metal crowns.
They are more commonly used as part of metal-ceramic crowns as bonding alloys.
When compared to high-noble and noble alloys, they are stronger and harder; they can be used in thinner sections (0.3mm as opposed to 0.5mm) however they are harder to adjust and are more likely to cause excessive wear on real opposing teeth.
Furthermore, there can be a problem with people with a nickel allergy.

Common base-metal alloys used in dentistry are:
Silver-palladium
Silver-palladium-copper
Nickel-chromium
Nickel-chromium-beryllium
Cobalt-chromium
Titanium
