Iron Powder for Thermal Conductivity Paste & Heat Dissipation Materials

Iron powder is a fine granular material made of elemental iron or iron alloys, with properties of good compressibility, high magnetic permeability, excellent thermal conductivity and certain reactivity. Its main uses include powder metallurgy (manufacturing mechanical parts), magnetic materials, welding electrodes, metal additives, chemical catalysts, food fortification (iron supplement), and environmental remediation (removing heavy metals from wastewater), serving as a core raw material to enh

The major producing and exporting countries include China, Germany, the United States, Japan, and Russia. These regions occupy a dominant position in the global iron powder market due to abundant iron ore resources, advanced smelting and processing technologies, and mature industrial chains.

Key quality standards to consider include iron content, particle size distribution, apparent density, compressibility, flowability, and impurity content (such as sulfur, phosphorus, and silicon). It is also necessary to comply with international standards such as ISO, ASTM, and GB, and ensure stable chemical composition and low harmful impurity content to meet different industrial application requirements.

Iron powder is usually packed in 25kg moisture-proof woven bags with inner plastic liners (to prevent oxidation and moisture absorption) or 1000kg jumbo bags. Packages are clearly marked with product grade, particle size, iron content, batch number and net weight. Bulk orders are delivered by container shipment, and the container is often lined with moisture-proof film to ensure the quality of iron powder during transportation.

Common incoterms include FOB (Free On Board), CIF (Cost, Insurance and Freight), and EXW (Ex Works). The specific selection depends on the negotiations between buyers and sellers regarding transportation responsibilities, insurance coverage, and cost allocation, with FOB and CIF being the most widely used in iron powder international trade.
