Direct factory export solutions tailored for high-humidity, high-reliability industrial applications across Bac Ninh, Thai Nguyen, Hai Phong, and Ho Chi Minh City industrial corridors.
As Vietnam firmly cements its role as Southeast Asia's primary hub for electronics assembly, electric vehicle (EV) manufacturing, semiconductor packaging, and green energy infrastructure, the requirement for high-purity, specialized raw materials has grown exponentially. Among these advanced materials, surface-coated aluminium powder serves as an irreplaceable foundation for thermal interface pastes, conductive adhesives, powder metallurgy, chemical synthesis, and anticorrosive industrial coatings.
Operating under the technical heritage of Toyo Aluminium K.K. Group since 2009, Hunan Ningxiang JiWeiXin Metal Powder Co., Ltd. (Toyal JWX) represents the pinnacle of Chinese manufacturing precision merged with Japanese quality control discipline. With an annual output exceeding 10,000 metric tonnes, our facility bridges the critical material gap for tier-1 OEMs and FDI enterprises operating across Vietnam's key economic zones.

Over the past decade, Vietnam has undergone an unprecedented transformation from a textile and light manufacturing center into a global technology assembly powerhouse. Heavy foreign direct investment (FDI) from South Korea, Japan, Taiwan, China, and the United States has turned Northern and Southern Vietnam into hyper-specialized industrial ecosystems.
Concentrated in Bac Ninh, Thai Nguyen, Bac Giang, and Hai Phong, giant complexes operated by Samsung, Foxconn, Pegatron, and Luxshare produce smartphones, laptops, display panels, and IoT devices. Coated aluminium powders are heavily utilized here as thermally conductive fillers in silicone gels and epoxy gap fillers to dissipate heat from microprocessors.
Anchored by domestic pioneer VinFast in Hai Phong, alongside major joint ventures (TC Motor, Honda, Toyota), Vietnam’s automotive sector is transitioning toward electrification. Coated powders provide fire-retardant thermal insulation for lithium-ion battery packs and feedstock for lightweight powder metallurgy (PM) structural components.
Vietnam’s solar module manufacturing plants require highly specialized aluminium pastes for back-surface field (BSF) metallization. Concurrently, Vietnam’s 3,260 km tropical coastline creates immense demand for advanced fluoropolymer-coated aluminium flake and spherical powders in marine anticorrosive coatings.
Uncoated atomized aluminium powder, while highly reactive and versatile, suffers from inherent limitations when processed in organic matrices, exposed to moisture, or stored in humid environments. The table below details the technical mechanisms through which Toyal JWX’s surface modification technology elevates functional performance.
| Coating Chemistry / Type | Core Mechanism | Primary Industrial Application | Key Performance Advantage |
|---|---|---|---|
| Silane Coupling Agents (e.g., Epoxy-silane, Vinyl-silane) |
Forms covalent chemical bonds between inorganic metallic aluminium and organic polymer matrices. | Thermal Pads, TIM Gels, Semiconductor Potting Resins | Reduces slurry viscosity by up to 45%, allowing higher filler loading (>85 wt%) without agglomeration. |
| Fatty Acid Modification (e.g., Stearic Acid / Oleic Acid) |
Creates a hydrophobic monomolecular layer around spherical or flake particles. | Powder Metallurgy Lubrication, Metallic Coatings | Improves dry powder flowability (Hall Flow <25 s/50g) and inhibits atmospheric oxidation during storage. |
| Inorganic Silica Encasement (Nano-SiO2 Shell Passivation) |
Forms an ultra-thin, highly dense, transparent ceramic barrier shell around the aluminium core. | Waterborne Industrial Paints, Solar Pastes | Zero hydrogen gas evolution in waterborne liquid formulations; extreme chemical stability in acid/alkali environments. |
| Fluoropolymer Shells (PTFE / PVDF Functional Coatings) |
Provides superhydrophobic, extreme-temperature dielectric separation. | EV Battery Thermal Insulation, Aerospace Composites | High breakdown voltage retention (>15 kV/mm) and flame retardancy in thermal run-away protection pads. |
Discover how Chinese technology and custom powder engineering solve real-world engineering challenges in Vietnamese factories.
Challenge: A tier-1 supplier of thermal interface materials in Bac Ninh faced high mixing torque and air entrainment when compounding 80% volume fraction aluminium powder into liquid silicone rubber (LSR).
Toyal JWX Solution: We supplied tailored ODM Fabricated Coated Aluminium Powder treated with a specialized silane coupling agent. The coated powder exhibited exceptional wettability, dropping matrix viscosity from 180,000 mPa·s to 95,000 mPa·s, allowing the plant to boost thermal conductivity to 4.8 W/m·K while maintaining high dispensing speeds.
Challenge: An auto-parts powder metallurgy manufacturer in Southern Vietnam experienced rapid oxidation and caking of raw aluminium powder inventory during monsoon seasons (relative humidity exceeding 90%).
Toyal JWX Solution: Transitioned the plant to fatty-acid passivated spherical aluminium alloy powder shipped in nitrogen-purged aluminum foil bags inside UN-approved steel drums. Active metal content loss after 6 months of local storage dropped from 4.2% down to less than 0.05%.
