Vintage Heruka Chakrasamvara and Vajrayogini Tantric Buddhist figurine.  The figure is about 3-1/4" tall and weighs 3.9 ounces.  The metal appears to be brass but has some reddish tones as well.

Looking into the meaning of the piece, I understand it is used to transform and use desire as a means to eradicate attachment, hatred & ignorance in order to gain the supreme state of a fully enlightened Buddha.
