In 2017, the Fusium management company entered into business following the acquisition of TMA by the owners of Saguenay Foundry.

Saguenay Foundry has been operating under this name since 1980 and its current factory located in Saguenay has been in constant evolution since 1965.

TMA came to be after the 1997 creation of the magnesium technology institute (ITM) which originated in the City of Quebec.  In 2004, TMA moved to Trois-Rivières, its actual location.
