We provide open cell metal foam, custom metal foam, and large-size metal foam solutions for energy storage, thermal management, filtration, electrolysis, aerospace, and noise reduction.

What is Porous Metal Foam?

Porous metal foam is a new type of engineering material characterized by its three-dimensional, highly interconnected open-cell or closed-cell structure. By introducing a large volume of gaseous pores into a solid metal matrix (such as nickel, copper, or silicon carbide), it combines the structural strength of metals with the unique physical properties of porous materials.

Core Functions

—High Porosity: Provides an extremely large specific surface area, making it ideal for heat transfer, catalysis, and filtration.
—Energy Absorption: Effectively absorbs impact and vibration energy, making it useful for explosion-proofing and dampening.
—Thermal & Acoustic Management: The metal framework allows for excellent heat conduction and sound wave dissipation.
—Lightweighting: Significantly reduces the weight of structural components without compromising metallic strength.

Technical Principles

Metal foams operate on the principle of structural engineering at the microscopic level. Instead of changing the chemical composition of the metal, the manufacturing process (such as electroplating on polymer foams, powder metallurgy, or sintering) creates a matrix of hollow voids. Think of it like a natural sponge made of solid metal: the interconnected ligaments provide structural integrity and conductivity, while the empty pores allow fluids, gases, sound, and heat to pass through with minimal resistance.

Huayan Intelligent Technology utilizes advanced sintering and deposition techniques to ensure precise control over PPI (pores per inch) and material density, offering customized solutions for demanding industrial environments.

Metal Foam Materials: A Deep Technical Comparison

Metal foam is not a single material. Its performance depends on the base material, alloy composition, pore structure, porosity, pore size, thickness, and operating environment. Selecting the right metal foam is about matching the structure to the actual engineering requirements.

Technical Properties & Applications

Detailed breakdown of the metal foams offered by HYM, focusing on where each material performs best based on structural and environmental requirements.

Nickel Foam

One of the most versatile open-cell metal foams. Its interconnected 3D pore network provides high surface area, fluid permeability, and electrical conductivity. Adjustable porosity (70–98%) and pore size (0.2–10 mm) for cryogenic hydrogen.

Sand-control filtration (H₂S, CO₂ resistance)
Hydrogen and cryogenic equipment (-253°C)
Gas diffusion & EMI shielding
Battery and electrochemical components

Copper Foam

Primarily selected when heat transfer and capillary performance are dominant. High-purity oxygen-free copper foam is specified as capillary wick material for vapor chambers. Config: 80–150 PPI, 70%–98% porosity.

Vapor chamber wicks & GPU cooling
AI-server thermal management
Heat spreaders & Liquid cooling

Engineering Selection Logic

Choosing Between Metal Foam Materials

The most useful way to select a foam material is to start with the dominant engineering requirement.

For Heat Transfer

Choose Copper Foam

When thermal conductivity and capillary transport are priorities. HYM vapor-chamber application uses high-purity copper foam as a capillary wick with 5–150 PPI and 70–98% porosity.

For High-Temperature Combustion

Choose Ni-Cr Foam

When the porous structure needs to function as a combustion or infrared-radiating surface. The specified NiCr burner configuration is designed for continuous operation at 700–1100°C.

For High-Temperature Filtration

Choose SiC Foam

When oxidation resistance, rigidity, and chemical stability are more important than electrical conductivity. Identifies molten-metal filtration, catalysis, and furnace applications.

For Electrochemical Applications

Choose Carbon Foam

Particularly suitable when electrical conductivity and high internal surface area are required. Listed applications include flow-battery electrodes and hydrogen-related equipment.

For Corrosion-Sensitive Filtration

Choose Nickel Foam

When an interconnected metallic filter structure must operate in demanding fluids. HYM specifies nickel foam for H₂S, CO₂, and high-salinity formation-fluid environments.

For Cryogenic Hydrogen

Choose Nickel Foam

HYM's application data specifically describes open-cell nickel foam for -253°C liquid-hydrogen systems, with adjustable porosity (70–98%) and pore size (0.2–10mm).
