    Those that sell cobalt platinum say it's great. It casts well (which
    is why the manufacturers like it), but that's about it. It is
    magnetic, which should give you some idea of what it's like to work
    with. It is all but impossible to solder or fuse with any degree of
    excellence. 

    Those that have to work with it will tell you it's a major pain in
    the behind. I personally won't touch it unless I absolutely have to.
    If you do have to work with it, keep it completely separate from any
    other platinum. It can contaminate your 900 Ir or 950 Ru it just like
    steel does.
