Electropoli reinforces its Zinc-Nickel production capacity!
In the context of REACH regulations, the aeronautics, defense and space (ADS) sectors are accelerating their transition to more environmentally-friendly technologies.
At Electropoli, we are supporting this development by increasing our production capacity, with the support of major customers and thanks to the qualifications obtained in recent years.
Our Isigny-le-Buat site is now equipped with four Zinc-Nickel treatment lines, complementing our certified processes: Surtec 650, electroless nickel and liquid paint.
A further step towards guaranteeing our customers a secure supply, in line with the most stringent market requirements!
On February 20, 2025, Nicolas DELAHEGUE, President & CEO of the Electropoli Group, was invited to attend the Economic and Commercial Exchange and Innovation Cooperation Meeting between Changzhou and Shanghai, organized as part of New Year's Week. Held along the banks of the Huangpu River in Shanghai, this event brought together over 200 key stakeholders from the industrial, scientific, financial, and cultural sectors, as well as representatives from the world’s 500 largest companies, chambers of commerce, and state-owned enterprises. This gathering was an opportunity to foster collaboration and explore synergies between Changzhou and Shanghai.
A speech by Changzhou Mayor Zhou Wei highlighted the city's commitment to deepening cooperation and stimulating innovation. Our partnership with the Changzhou Xitaihu Science & Technology Industrial Zone strengthens our commitment to developing cutting-edge surface treatment technologies in the electric mobility and aeronautics sectors.
Electropoli France achieved a new qualification in Electroless Nickel treatment according to Pr-1200, issued by Safran for our site in Isigny-le-Buat.
This certification, obtained in May 2025, strengthens our position in the aeronautics sector.
🎯 Objectives of this qualification:
• Expand our range of treatments and target new aeronautics markets, particularly connectors
• Enable dual treatments: Ni Chemical + Zinc Nickel on the same part
• Process a wide variety of materials: steel, stainless steel, copper, aluminum, titanium
• Adapt to parts of all sizes, from connectors to 1-meter-long axles
🧪 Demanding R&D work
This qualification required:
• A comprehensive series of standard tests: corrosion, embrittlement, adhesion, thickness, porosity, conductivity
• Advanced characterization to meet Safran's exacting standards
This new recognition confirms Electropoli's expertise in high value-added surface treatments and our ability to support major aeronautics contractors.

- 🔬 APOLLO Project: Towards a new generation of sustainable, high-performance industrial surface treatments
Electropoli is honored to be taking part in the APOLLO (Aluminum Protection through cOnversion without harmfuL hexavaLent chrOmium) project, a strategic initiative led by IRT M2P in collaboration with industrial partners and academics. Launched in June 2024, this project is part of a strict regulatory framework, imposed by the European REACH regulation, and aims to transform surface treatment methods for aluminum alloys in order to meet today's environmental and industrial challenges.
🎯 Objectives of the APOLLO project
The APOLLO project has two main aims:
1️⃣ Enhancing the robustness of TCP (Trivalent Chromium Process) treatments:
Improving corrosion protection performance, particularly in demanding environments such as aerospace and defense.
Optimization of surface preparation steps to ensure uniform and reproducible application of conversion layers.
2️⃣ Developing a chromium-free alternative:
Based on promising formulations, such as those based on potassium permanganate, which offer comparable performance to current CrIII- or CrVI-based treatments.
🌍 Industrial and environmental challenges
The APOLLO project is not limited to a simple technological improvement. It also aims to:
Guarantee compliance with European standards while preserving the competitiveness of manufacturers.
Protect workers' health by eliminating hazardous substances.
Reduce the overall environmental impact of surface treatment processes.
📈 Prospects and benefits
APOLLO marks a crucial step in the transition to sustainable processes. The expected results include:
Robust industrial qualification of TCP solutions.
Wider adoption of chromium-free alternatives.
Better control of processes within the supply chain.
Together, we are moving towards an industry that is more respectful of the environment and better prepared for the challenges of tomorrow.
The future of surface treatment is being built today with ELECTROPOLI and APOLLO.
