Metal Powders

For the past thirty years PSI Ltd has utilised its own atomisation technology to provide clients with a Powder Production Service. Those clients wanting to develop metal powder technology and applications are able to commission PSI to manufacture their specific alloy compositions to order.

PSI are responsive to clients’ requirements for trial batch or R&D quantities manufactured within short delivery times.

PSI use close-coupled inert gas atomisers with vacuum, inert gas melt chambers for the production of low oxygen, ultrafine, spherical powders.  We have the expertise to develop novel alloy compositions and manipulate the atomisation process for specific particle sizes and distribution.

For powders sensitive to exposure to air or moisture, inert gas glove box facilities are available. Particle size analyses are performed if required and the powders sieved according to clients’ requirements.

Novel powder development research can be conducted on clients’ behalf as are feasibility studies for scale-up projects. Naturally, we welcome the opportunity to meet our clients and discuss their powder needs, both immediate and longer term, in an atmosphere of confidentiality and common purpose.

 

PSI has the capability to produce a wide range of powders, here are a few examples:
