More than twenty years dedicated to zinc-based materials — from Changsha to three production bases serving customers across China.
Hunan New Welllink Advanced Metallic Material Co., Ltd. (stock name "Welllink", code 920634) was founded in November 2002 and specializes in the research, development, manufacture and sale of zinc-based materials such as spherical zinc dust and zinc flake. On 24 November 2022 it listed on the Beijing Stock Exchange, becoming the first zinc dust company on the BSE.
The company runs three production bases: Hunan Welllink New Material Co., Ltd., Sichuan Welllink Advanced Metallic Material Co., Ltd. and Welllink Advanced Metallic Material (Nantong) Co., Ltd. Current annual capacity is 25,500 t in Hunan and 32,000 t in Sichuan, and the Jiangsu base will add 25,000 t when complete — 82,500 t a year in total (including capacity under construction), making Welllink China's largest zinc dust producer by capacity (excluding capacity that industry peers have under construction or planned).
Our spherical zinc dust is widely used in zinc-rich anti-corrosion coatings, sherardizing, the chemical industry, non-ferrous metallurgy, pharmaceuticals and pesticides, diamond tools and friction materials. Our zinc flake serves mainly the automotive, home-appliance, defense and new-energy supply chains as a key raw material for chrome-free zinc-aluminum, Dacromet and zinc-rich anti-corrosion coatings, protecting and finishing steel parts, steel structures and hardware.
Welllink builds strong R&D into every part of production and operation. It holds a series of core technologies and more than 80 national patents, 18 of them invention patents; has helped draft national and industry standards including Zinc-aluminum coatings — Technical specification (GB/T 26110-2025), Metallic coatings — Zinc diffusion coatings on iron and steel — Sherardizing — Technical requirements (GB/T 43884-2024), Diffusion corrosion-resistant coatings on iron and steel parts — Technical specification (pending approval), Zinc-rich primers (HG/T 3668-2020) and Safety code for zinc-aluminum coating operations (T/CSEA 17-2021); and has received more than 100 honors and qualifications, among them national Specialized and Sophisticated "Little Giant" Enterprise, National High-Tech Enterprise, Hunan Manufacturing Single Champion Product (zinc-based materials), Sichuan Specialized and Sophisticated SME, Hunan New Materials Pilot Platform, designated builder of a Hunan Manufacturing Innovation Center, and Provincial Enterprise Technology Center. It is a leading company in zinc-based powder materials, in R&D, market share and brand recognition alike.
Dear Friends,
Thank you for your interest in Hunan New Welllink Advanced Metallic Material Co., Ltd., and for taking the time to visit our website. I hope this visit will be the start of an acquaintance that grows into mutual understanding and lasting friendship.
I believe that every meeting of this kind is a rare piece of good fortune. In a world this vast, among so many people, our paths have crossed — and I hope that, in time, we will become long-term partners and true friends.
We were shaped by the culture of a large, long-established state-owned enterprise, and witnessed first-hand the triumphs and trials of its more than seventy-year history. We have also known the hardship of building a business from nothing, and the satisfaction of earning our place in the market and growing stronger year by year. Through it all, we have held fast to two time-honored Chinese maxims: "character comes before business" and "heaven rewards the diligent." They guide how we run the company, treat our employees, serve our customers and reward our shareholders, and they have made us a trusted and respected company in China's zinc processing industry — young but mature, steady but dynamic. Like you, we stay grounded and persevere through every step of the journey, while looking ahead with hope and confidence.
We firmly believe that integrity and mutual benefit are the foundation of lasting success, and they are the standard by which we choose our customers and partners. While we are eager to work with as wide a range of partners in China and abroad as possible, we focus above all on customers to whom we can add real value — those who share our commitment to integrity and mutual benefit, and who want to grow alongside us.
We are convinced that business success cannot be separated from high ethical standards. Profit matters to us, but what matters more is championing ethical business practices and professional integrity in an intensely competitive global market. An unwavering commitment to these principles is the cornerstone of who we are.
Competition in our industry is fierce. Our experience and technology are valuable, but quality and service matter most. They keep our products competitive and our customers satisfied, and they are our business philosophy put into practice. Through our professional expertise, we promise products you can trust; through our company culture, we promise to be people you can rely on.
Finally, on behalf of everyone at Hunan New Welllink, and personally, I would like to express my sincere gratitude to all the friends who have supported us over the years. To everyone considering working with us, I extend a warm welcome and my very best wishes.
I look forward to a future of shared success and lasting friendship.
To specialize deeply in our field, crafting high-quality products that offer the best value, and to keep creating value for our customers and our industry.
Win customers with sincerity and fine products — and win customers for our customers.
Welllink has received more than 100 honors and qualifications, including national Specialized and Sophisticated "Little Giant" Enterprise, National High-Tech Enterprise, designated builder of a Hunan Manufacturing Innovation Center, Hunan Manufacturing Single Champion Product (zinc-based materials), and Sichuan Specialized and Sophisticated SME.

With provincial and municipal innovation platforms including the Hunan Provincial Enterprise Technology Center, the Hunan New Materials Pilot Platform and a designated Hunan Manufacturing Innovation Center, the company has built up a body of original, in-house core technology and a complete R&D–pilot–production innovation chain.



We have developed our own pilot and production equipment for distilled ultrafine spherical zinc dust, atomized near-spherical and irregular zinc powder, and dry- and wet-process zinc flake. High-end precision instruments — ICP spectrometers, laser particle size analyzers, oxygen analyzers, full-spectrum spark direct-reading spectrometers, atomic absorption spectrophotometers, coating colorimeters, salt-spray test chambers, coating thickness gauges and fineness-of-grind gauges — support a quality control system covering the whole process from raw material to finished product.
Our technical team combines sound theory with hands-on experience rarely found in the industry, bringing together high-caliber specialists from several disciplines. The equipment and products it developed in-house for zinc flake and zinc-aluminum alloy flake have broken through foreign technology barriers, reached internationally advanced levels and replaced a share of imports.
