ultrafine copper powder

PJ-139 is a new type functional basic metal powder material produced by wet chemical reduction method, particle size control and antioxidant treatment and so on talent technology. It combines the advantages of traditional copper powder and nano-copper powder. Product Features 1) The particle size is between 0.5um and 1.5um(about 18000 mesh) which overcomes the particle size control bottleneck of traditional copper powder (about 2500 mesh) and with more obvious copper based functional powder features compared with nano-copper powder. 2) Produced by wet chemical process technology,the purity is high up to 99.9%. 3) Spheroid particle, easy to be dispersed. 4) Prominent anti-oxidant ability: There is no obvious oxidation kept in the air for 15 days in normal temperature or dried at 200 centidegree. Typical Quality Index Appearance deep red-brown paste Specific gravity 2.5 2.7g/cm3 Particle size ≤1.5um Copper powder content ≥67.5% (the other content are safe and non-toxic water soluble anti-oxidative materials) Water soluble salt ≤0.02% Oxygen content ≤0.10% Application As a new type functional basic metal powder material,due to the great anti-oxidant ability, it is widely used in the fields of powder metallurgy, diamond tool, welding electrode, frictional and lubricant material, catalyst, conductive and anti-electromagnetic coating, conductive ink, conductive copper paste, machine precise process, medical and biological and so on.
