Copper & copper alloy powder is a fine granular and crushed copper or copper alloy powder. Several processes are used to make this powder. One of the prominent methods entails molten copper/copper alloy sprayed under very high pressure to yield a fine granular powder. Several types of copper & copper alloy powders – 1-dimensional (ultrathin rods & needles), 2-dimesional (flake & dendritic), and three dimensional (spherical & nodular) – can be manufactured depending on the type of atomizing gas used to ‘blow’ the molten copper/copper alloy from a nozzle tip. Electrolysis and hydrometallurgy is another way of producing copper & copper alloy powder. These methods produce different types of powders. Copper & copper alloy powders can be manufactured in various particle sizes, ranging from 5 microns to more than 1000 microns, and shapes. Copper powder of purity more than 99% is available commercially. Components fashioned from these powders usually tend to have electrical conductivities of 85% to 95% IACS as either pressed or sintered. In some cases, higher conductivities, up to 100% IACS, can also be achieved by further densification. High electrical conductivity translates into high thermal conductivity. Thus, copper powder metallurgy parts offer substantial benefits in the production of electronic & electrical components, where electrical or thermal conductivity is a vital characteristic.

Copper & copper alloy powder is used in various applications. Copper base powders are used in applications such as abrasive wheels, fungicides, brake linings, dead & counter weights, paints, bushing, catalysts, heat sinks, bearings, brazing compounds, fuse parts, lubricants, and printed circuits. Copper & copper alloy powder is employed in various component manufacturing, wherein several powder metallurgy techniques are employed. Furthermore, the use of copper & copper alloy powder as biocide in marine paints is common. Thus, versatility of powdered copper & copper alloy is one of the major drivers of the market. The market for copper & copper alloy powder is driven by factors such as rise in demand in the electrical & electronics industry and industrial machinery manufacturing. It is also a preferred metal powder in rapid prototyping and powder metallurgy.

Based on type, the copper & copper alloy powder market can be divided into 1-dimensional shape (ultrathin rods & needles), 2-dimesional shape (flake & dendritic), and three dimensional shape (spherical & nodular). Based on manufacturing process, the market can be segmented into atomization, electrolysis, hydrometallurgy, and others. In terms of end-user industry, the copper & copper alloy powder market can be classified into automotive, aerospace & defense, building & construction, chemical, electronics & semiconductors, paints & coatings, agriculture, and others.
