AM Powders are shipped to you with test certificate

Uniquely compared to other metal powder suppliers, Carpenter Additive offers AM powder manufactured by several different methods. Each process has distinct advantages and disadvantages. The common processes are explained below. However, for specific enquiries, including information on our range of pre-blended Tungsten Carbide containing Cobalt and Nickel matrix AM powders, please contact us directly.

Carpenter Additive is committed to adding quality to the AM process by supplying well defined powders and services that support your needs, along with the certifications to prove it.

Methods for AM Powder Manufactured Production

GAS ATOMISATION

GAS ATOMISATION

Considered the most common method of metal powder production, elemental feedback is melted under an air or inert gas blanket, or under vacuum. The chamber is then backfilled with gas to force molten alloy through a nozzle where high velocity air, N, HE or AR gas impinges onto the flowing melt and breaks it up. This powder is mostly spherical, with some asymmetrical particles and satellites present and is mostly used for NI, CO and FE alloys, also available for TI and AI alloys.

WATER ATOMISATION

WATER ATOMISATION

Similar to gas atomization, water is instead employed as the atomizing medium. This method is used mostly for unreactive materials such as steels as it produces irregular shaped powder particles.

PLASMA ATOMISATION

PLASMA ATOMISATION

A relatively new technique that produces high quality and extremely spherical metal powder, plasma atomization feeds wire feedstock into a plasma torch that, with the aid of gases, atomizes the powder. Size ranges from 0 – 200 micron. This atomization is limited to alloys that can be formed into a wire feedstock.

EIGA

EIGA

EIGA works with all metal alloys, but is most economic with reactive alloys like Ti. Feedstock, in the form of bar, is rotated and melted by an induction coil and a film of molten metal flows downwards into a gas stream for atomization. Therefore, material does not come in contact with either crucible or electrode during process. Powder size is 0 to 500 micron and morphology is similar to gas atomised. EIGA is cost-effective, clean, ideal for small batches and produces small diameter powder.

PREP

PREP

Prep is similar to the EIGA process, but the rotating feedstock bar is melted when it comes into contact with a plasma. Metal powders are extremely spherical but yields are limited below 100 micron.

CENTRIFUGAL ATOMISATION

CENTRIFUGAL ATOMISATION

Centrifugal atomization is a smart compromise between gas and plasma atomization: it’s a simple process not currently in wide-spread use. The process generates powder that is more spherical and has lower entrapped gas porosity than Gas Atomization, but not to the quality of Plasma Atomization or PREP. Additionally, it’s more cost effective than both PREP and Plasma Atomization. Best suited to larger batch sizes of less reactive low melting temperature alloys, Centrifugal Atomization can also make Nickel superalloys.

PLASMA SPHEROIDISATION

PLASMA SPHEROIDISATION

Carpenter Additive uses high-energy plasma to produce highly spherical and dense AM metal powders. Additionally, the process uses plasma to transform agglomerated powders produced by spray drying or sintering techniques, or angular powders produced by conventional crushing methods, into spherical powder. Powder is gravity fed from the top and it is sprayed through the plasma by using various nozzle types depending on specific powder characteristics. Individual powder particles are completely melted and solidify in a spherical shape.

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.

The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham.
