I am looking for a list of investment casting companies/foundries (no
sand casting companies/foundries, please, since these are doing
lower-end products that I am not interested in) in China that are
specialized in making cast products out of superalloys, titanium,
nickel or aluminum (anything but iron or steel).

These companies should deliver products into at least one the
following industries:  aerospace (e.g., for structures or engines),
defense (e.g., as components for land vehicle, projectiles, armament),
medical products (e.g., for prostheses, hip joints), equipment for
process industries (e.g., components for chemical plants or oil
refineries), oil & gas exploration (e.g., as components for drilling
equipment, pipeline fixtures), automotive/trucks (e.g., as wheels for
turbo chargers).

I expect a list of at least 25 companies (in an MS Excel spreadsheet)
with their name, product lines, industries served, address, web
address, and any observations you'd find noteworthy, ideally any
information regarding their size (revenues, number of employees,
production capacity).

Is a duplicate question except asking for 10 companies.

Thanks for your comment. As noted, the questions are indeed similar,
but with focus on two distinct geographical markets: this one focuses
on China, the other one focuses on Japan.
