We are working on a new aluminum fixture. It is basically an aluminum
spine with many 6061-T6 pins sticking out. Currently we drill the
holes inside the spine and hammer the 5/32" 6061-T6 pins inside. Is
there anyway to cast aluminum with many 6061-T6 pins embedded (they
will stick out after the casting)?


absolutely no practical way possible of doing what you ask.

....which was 'can I cast aluminium with aluminium chaplets'.

absolutely not. aluminium has such a heat transfer that molten
aluminium coming into contact with aluminium pins would soon have them
molten and fluid.
