Copper Powder (Atomized Metal) - Weight: 1kg - By Inoxia

Product Information

To 0,1 g of fine copper powder obtained above, 0,3 g of a surfactant (sorbitan fatty acid ester, "LEODOL", a product of Kao Corporation) and 150 g of water were added, and this mixture was subjected to ultrasonic dispersion treatment. Thereafter, the obtained dispersion was analyzed for agglomerate particle diameter by means of a laser type particle size distribution analyzer. As a result, it was found that the agglomerate particle diameter (on the average) was about 3 µm. P.E. Matthews, "The Mechanical Properties of Brass and Developmental Nonferrous P/M Materials," Int.

Copper-lead alloys containing about 30% lead are stronger but have less satisfactory surface properties and are usually used with a thin lead-tin overlay.Copper and copper alloy powders have been used in industrial applications for many years. Probably the best known is the self-lubricating bearing which was the first major application and still accounts for about 70% of the granular copper powder used. This application takes advantage of the ability to produce a component with controlled interconnected and surface-connected porosity. The production of metallic filters also takes advantage of this ability.

Although these methods, which usually produce powders of relatively large particle diameters, have been advanced to produce finer copper powders; By controlling the manufacturing conditions or by sieving, the production efficiency is low and the fineness achievable by such methods is limited.

Therefore, the present invention, which provides a practical and novel process for the industrial production of fine copper powder, is of considerable importance. In addition to copper powder we can produce powders of copper alloys such as brass and bronze. Brass powder and bronze powder can be made in different grades based on your applications.
