CENTERLINE FEEDSTOCK POWDERS

 

CenterLine has formulated a variety of feedstock powders for surface repair and fabrication, corrosion protection, sealing, and cleaning applications. The following lists the more commonly applied powder formulations we have available. All of our powder materials have been selected to have the right combination of particle size, shape, and purity.

Our low-pressure cold spray feedstock powders are quite unlike powders formulated for high-pressure cold spray or thermal spray processes. Our powder blends may contain constituents in the design that ensure that the coating deposit has properties tailored to a particular application(s).

Note that standard spherical and heavily oxidized powders will not provide acceptable equipment performance or reliably applied coatings. For results that you can count on, you should use only CenterLine powders with CenterLine Cold Spray equipment. 

CenterLine powders are available in the following price competitive bulk packages:

          Package #                   Container Volume                   Container Size
              10                               200 ml                              250 ml

Safety Considerations
• Handle powder with care, wearing the recommended protective equipment.
• Do not ingest or smell powder.
• The powder should be stored at room temperature in its original container.
• Do not reuse already sprayed powder.
• Do not use contaminated powder or powder that you suspect as being contaminated.

 

Note: Effective May 1, 2009, CenterLine is adopting a revised powder blends part numbering system.  Below is a partial list of currently available powders with reference to the original catalogue number and the revised number.  Please continue to check our site for additional updates. Note that the listed suggested setup parameters apply exclusively to CenterLine’s SST Cold Spray equipment and are based on compressed air operation. The detailed parameters are not necessarily applicable to other cold spray processes.
