This series of products is copper powder produced through atomization and special anti-oxidation treatment. The powder has an irregular morphology, high purity (Cu > 99.5%), excellent flowability, formability, and high green strength. The resulting powder features irregular, porous particles that offer both flowability and compressibility, making it highly suitable for powder metallurgy (PM) molding. The powder grades for powder metallurgy are designed with controlled dimensional change characteristics, allowing bearing manufacturers to select the appropriate grade for the desired dimensional control during production. It is primarily used in industries such as self-lubricating bearings (Cu-Sn mixed powder), powder metallurgy, metal graphite carbon brushes, and friction materials.
