Description
Premium Zinc Foam – 40–110 PPI Open-Cell Metal Sheet (Customizable)
Zinc foam is an advanced porous metallic material characterized by a three-dimensional open-cell network structure. Engineered for applications that demand a balance of lightweight form, electrical conductivity, large surface area, and customizability, zinc foam has emerged as a preferred material in cutting-edge industries, particularly in electrochemistry, energy storage, catalytic systems, and EMI shielding.
At Shaanxi Nickel Titanium Copper Metal Co., Ltd., we provide high-purity open-cell zinc foam sheets with adjustable porosity ranging from 40 to 110 pores per inch (PPI), ensuring compatibility with both standard and highly specialized engineering requirements.
🔹 What Is Zinc Foam?
Zinc foam belongs to the family of metal foams—a category of materials that exhibit cellular structures filled with pores. Unlike closed-cell foams that trap air inside sealed cavities, open-cell zinc foam maintains a fully interconnected structure that permits the passage of gases, liquids, and ions. This quality, combined with zinc’s natural electrochemical activity, makes it an excellent choice for zinc-air batteries, catalyst carriers, and functional filtration media.
The foam is typically manufactured by template replication, chemical vapor deposition, or powder metallurgy techniques, depending on the desired pore size and density. The result is a rigid yet lightweight sheet with exceptional surface area and excellent functional versatility.
🔹 Key Technical Features
-
High Purity: Zinc purity ≥99.9% ensures stability and reliable performance in electrochemical and thermal systems.
-
Customizable Porosity: Standard pore range from 40 to 110 PPI, but other ranges like 20–30 PPI (larger pores) can be developed upon request.
-
Excellent Electrical Conductivity: Makes it suitable as an anode material in metal-air batteries.
-
High Surface Area: Enables enhanced reaction efficiency in catalytic and electrode systems.
-
Open-Cell Network: Allows free passage of air, water, ions, and electrolytes—ideal for electroplating, filtration, or gas diffusion layers.
-
Corrosion Behavior: Zinc’s predictable corrosion pathway (sacrificial anode) is beneficial in galvanic environments.

🔹 Typical Applications
Zinc foam’s multifunctional properties make it suitable for both emerging technologies and traditional industries. Its most notable applications include:
🔋 Zinc-Air and Rechargeable Batteries
Zinc foam is widely used as a high-performance anode in zinc-air batteries due to its uniform current distribution and improved electrolyte flow. The high porosity enhances ion exchange, increases charge density, and minimizes polarization effects.
⚗️ Catalytic Substrates
Its open structure and high surface area make it an ideal support for catalytic metals like platinum or palladium. Zinc foam substrates are increasingly used in hydrogenation, oxidation, and reduction processes in chemical synthesis.
🌡 Heat Transfer and Thermal Dissipation
Zinc’s relatively low melting point and decent thermal conductivity allow zinc foam to act as a lightweight heat sink or fluid-phase heat exchanger, especially in compact electronics or cooling systems.
⚡ Electroplating and Metal Recovery
Due to its predictable redox behavior and electrical conductivity, zinc foam serves as a sacrificial material in electrochemical processes, helping in uniform plating, metal ion scavenging, or galvanic protection.
📡 EMI Shielding
Its structure disrupts electromagnetic radiation, while its conductivity allows for grounding—making it a lightweight, flexible alternative to solid metal enclosures in shielding-sensitive electronics.
