    G'day Daniel - a small point perhaps, but Tony Eccles of APECS
    Investment Casting in Melbourne Australia is the bloke who developed
    these alloys 30 years ago  - Tony holds the patents and it's my
    understanding that U.P.M.R. operate under license from APECS. 

    There is useful technical information about these alloys heRe:

    as well as some historical stuff. 

cheers
