R&D Capabilities

FDHJ Alloy has gradually realized a strategic transformation from the domestic market to the international market.

It has successively passed the qualification certifications of international electrical production giants such as ABB,

Schneider, Omron, Benedictor, and Tyco, Austria, and successfully Entering the international high-end market,

the company has already conducted substantial cooperation with the above-mentioned enterprises. In the next few years,

on the premise of ensuring the growth of sales with domestic customers such as Chint Electric, Delixi, Hongfa, etc.,

the company will strengthen cooperation with international high-end customers to achieve expansion from the

domestic market to the international market.

Customers

Current customers are Schneider, ABB, Siemens, Mitsubishi, Tyco and other Fortune 500 companies, as well as

Eaton, Legrand, Chint , Hongfa and other well-known electrical companies at home and abroad, are exported to

more than 20 countries and regions in Europe, America and Asi
