It can be turned; how well it works depends on the specific alloy, the tool, and your machining practices. Here's a little info:
"Turning
The use of tungsten carbide tipped tools is considered desirable. It is most important
that the work should be held rigidly and that tools should be properly supported, with
minimum overhang from the tool post. To obtain the best results, equipment must be
kept in good condition, as excessively worn headstock bearings and slides will give rise
to tool chatter and rapid tool breakdown. The first roughing cut on a casting should be
deep enough to penetrate the skin, and a steady flow of soluble oil is essential for both
roughing and finishing cuts. The work must be kept cool during precision machining; if it
is allowed to heat up, difficulty will be experienced in maintaining accuracy.
Suitable designs for tungsten carbide roughing and finishing tools are illustrated in
Figure 1, and speeds and feeds recommended for use with these tools are given in
Table 9. High efficiency with carbide tipped tools is attained by using a light feed, a
moderately heavy depth of cut and the highest cutting speed consistent with satisfactory
tool life. " https://www.copper.org/publications/...num_bronze.pdf
