ELBA and Rielka is a family-owned company, with expertise passed down over three generations.

ELBA was created in 1949 to import electrical components for the post-war reconstruction in France.

RIELKA was created in 1957 to produce and assemble contact rivets in France.

The two companies have developed to complement their network of industry partners and expertise in the electrotechnical industry.

Louis Hardy and George Hardy, built and structured ELBA and Rielka.

Anne-Laure Hardy bought the group in 2012 with the objective to perpetuate the acquired skills and to find a unique positioning in a market that is both demanding and competitive.

In 2013 we moved to a purpose built site at Aulnay sous Bois in 2013. This marked the beginning of a new era of development that allows us to respond more efficiently to the specific requirements of our customers.

In 2016, we gained qualification for the very demanding and specialised process of induction brazing for aerospace components.

In 2018, an ambitious automation project is about to come to life. To be continued
