Spaying powder is a metallic powder supplied by Hunan Research Institute Of Metallury And Material, based in Changsha, China. The product is offered in mixed‑grade ferrous and non‑ferrous compositions and is available in two mesh sizes, 150 mesh and 300 mesh, as stated in the source. Buyers receive the powder in bulk kilogram batches suitable for thermal‑spraying and powder‑metallurgy processes. The institute’s profile shows a harbour trust tier and a zero‑percent response rate, with no average response time recorded.
Typical particle size for 150 mesh powder lies between 100 µm and 150 µm, while 300 mesh material ranges from 45 µm to 75 µm, which matches standard classification for thermal‑spray feedstock. Bulk density for such mixed‑grade powders commonly falls in the range of 3.5‑4.0 g cm‑3, and a Hall flow rate of 12‑18 seconds per 50 g is regarded as acceptable flowability. Chemical purity is usually above 99 % with oxygen content below 0.2 % and moisture less than 0.5 %, ensuring consistent coating performance. Although the listing does not list specific certifications, powders intended for industrial use are generally required to meet ISO‑9001 quality management and relevant ASTM standards.
The powder is widely used for thermal‑spray coating of turbine blades, automotive components and aerospace parts, as well as for powder‑metallurgy sintering of wear‑resistant inserts. Typical purchasers are OEM manufacturers and specialised coating contractors who need consistent feedstock for high‑temperature deposition. Common trade arrangements involve FOB or CIF shipment from the port of Shanghai, with payment often secured through L/C or T/T, but exact terms should be negotiated with the institute. Buyers should also confirm lead‑time estimates and any required export licences for metal powders before placing an order.

Importers should first confirm that the institute holds any necessary export licences for metal powders and that the product complies with Chinese export regulations. Request a recent certificate of compliance and a detailed material safety data sheet to verify mesh size, purity and flow characteristics before committing to purchase.
Logistics for bulk metal powder typically involve freight calculations based on kilogram weight and volume. Buyers often select FOB or CIF terms from Shanghai and arrange payment through L/C or T/T, but the precise incoterm and payment schedule must be agreed with the supplier. Anticipate lead times that accommodate powder handling safety procedures and any required customs documentation for hazardous material imports.
Quality assurance commonly includes third‑party sampling to verify particle size distribution, bulk density and chemical composition. An independent laboratory test for oxygen and moisture content can confirm that the powder meets industry standards. Secure documentation such as a certificate of analysis, packing list and compliance certificates to streamline customs clearance and downstream processing.
