To improve the fracture resistance of a dental casting alloy without giving rise
to undue hardness thereof it is proposed that the dental casting alloy substantially
consists of

| 28-34 |
wt % |
Cr, |
| 5-9 |
wt % |
Mo, |
| 1-3 |
wt % |
W, |
| 0.9-1.3 |
wt % |
Si, |
| 0.15-0.3 |
wt % |
Mn, |
| 0.1-0.3 |
wt % |
N, |
| 0.1-0.3 |
wt % |
C, |
| 0.1 |
wt % |
Ni, |
|
- manufacturing impurities,
- remainder cobalt,
- the ratio of the content of Mo to that of W being in the range of from
about 3:1 to about 5:1 and the ratio of the content of Si to that of Mn being in
the range of from about 3:1 to about 9:1.
