Import Aluminum Powder For Aac Blocks — Buy in Bulk from Supplier in China

This aluminum powder is engineered for Autoclaved Aerated Concrete block production, supplying the reactive aluminum needed to generate hydrogen gas during the mixing stage. The fine particle size ensures uniform gas distribution, producing a consistent cellular structure in the finished blocks. Originating from Hebei, China, the material is processed under controlled conditions to maintain stability and reactivity for AAC applications.

The powder is typically composed of 98-99.5% pure aluminum with a fine mesh size, often in the 200-400 mesh range, which is standard for AAC gas-generating agents. The petal-shaped or spherical particle morphology enhances dispersion in the slurry, while the low iron and silicon content minimizes impurities that could affect block quality. Industry practice for AAC aluminum powder typically targets a hydrogen generation efficiency of 85-95% under standard test conditions.

AAC block manufacturers source this grade primarily for its role in reducing bulk density while improving thermal insulation and acoustic properties. Buyers confirm bulk density, specific surface area, and reactivity rate before ordering, as these directly impact the block’s physical characteristics. The material is commonly packed in 25 kg or 50 kg bags with nitrogen-sealed inner liners to prevent oxidation during storage and transit.

Xinji Guangyuan Metal Powder Co., Ltd. operates from South Chaoyang Road in Xinji, Hebei, China, a region known for metal powder production. The supplier is classified under the imported tier with a harbor trust level, indicating a baseline of verified trade activity. The address places the company within Shijiazhuang’s industrial zone, accessible via major logistics routes to Chinese ports.

The company’s profile does not state a response rate or average response time, so buyers should directly contact the supplier for technical queries or order confirmation. No certifications, production capacity, or client references are provided in the listing, so these must be requested separately. The supplier’s focus appears to be on aluminum powders for industrial applications, with no additional product lines or company history disclosed.
