Ashtadhatu (lit.'eight metals'), also called octo-alloy, is an alloy often used for casting metallic idols for Jain and Hindu temples in India.[2][3][4]

Ashtadhatu Shakti of 8th century, in Shri Shakti Devi temple, built by Raja Meru Verman of Bharmour, in Chhatrari, Chamba, Himachal Pradesh.[1]

The composition is laid down in the Shilpa shastras, a collection of ancient texts that describe arts, crafts, and their design rules, principles and standards. Ashtadhatu is used because it is considered extremely pure, sattvic of Sattva, in Hinduism, and does not decay, and it is also restricted to the gods Kubera, Vishnu, Krishna, Rama, Kartikeya, and goddesses, Durga and Lakshmi.[5]

Its traditional composition is gold, silver, copper, lead, zinc, tin, iron and antimony or mercury.[6][7][8] In genuine Ashtadhatu, all eight metals are in equal proportion (12.5% each).

Sometimes an alloy idol is termed Ashtadhatu, even when its exact composition is not known. Because the metals were mixed in equal proportions, the casting was very rough and needed to be thoroughly polished. Due to their sacredness and rarity, these pure idols are often stolen.[9]
