CENTERLINE FEEDSTOCK POWDERS

 

CenterLine has formulated a variety of feedstock powders for surface repair and fabrication, corrosion protection, sealing, and cleaning applications. This site lists the more commonly applied of more than 100 powder formulations we have prepared. All of our powder materials have been selected to have the right combination of particle size, shape, and purity.

These low-pressure cold spray feedstock powders are quite unlike powders formulated for the high-pressure cold spray or thermal spray processes. Our powder blends may contain several constituents so that the coating deposit has properties tailored to a unique application.

Standard spherical and heavily oxidized powders will not provide acceptable equipment performance or reliable applied coatings. For results that you can count on, you should use only CenterLine powders in our machines. These powders are also available in price competitive bulk packages.

  
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.

Powder Characteristics & Preliminary Set-up Parameters

Metal Group Catalogue Number Description of Coating Characteristics Suggested Setup Parameters Other Process Considerations
Aluminum KSF-A017-1 Special size distribution blend of pure aluminum. Excellent deposition and smooth coatings. Can produce very thick deposits.
Hardness: 25-30 HRB		 Air Temperature: 375C Max.
Gun Pressure: 85-90 psi
 Gas temperatures approaching 375C or greater can cause premature nozzle clogging. Try intermittent use or lower gas temperature.
Aluminum KSF-A027 General purpose aluminum build up material containing aluminum, zinc and alumina. Good for repairing a variety of components. Medium hardness and good machinability. Can produce very thick deposits. Air Temperature: 425C
Gun Pressure: 85-90 psi		 Although very workable, this material can be challenging to grind down using conventional abrasive paper. Perhaps choose a softer blend or consult with SST for other recommendations.
Aluminum KSF-A050 Blend of aluminum and alumina. Very good deposition. Good for repairing a variety of components. Zinc free. Air Temperature: 450C
Gun Pressure: 85-90 psi		 Although very workable, this material can be challenging to grind down using conventional abrasive paper. Perhaps choose a softer blend or consult with SST for other recommendations.
Aluminum KSF-A27705 Aluminum silicon alloyed powder with 12% silcon (equivalent to aluminum 4047). Has potential to be a good choice as a brazing material. Air Temperature: 500C Max.
Gun Pressure: 85-110 psi.		 Higher temperature and pressure are key to achieve good deposition results.
Aluminum KSF-A21339 Pure fine aluminum powder. Excellent deposition and smooth deposits. Also very high density and excellent bonding. Air Temperature: 300C Max.
Gun Pressure: 85-90 psi.		 This material is very sticky and can easily cause nozzle clogging. Consider using a blended material before considering this. Temperatures as low as 200C will deposit material and avoid nozzle clogging but deposition will not be efficient. Consider using a shorter nozzle available from SST to avoid nozzle clogging.
Aluminum KSF-A053 A blend of aluminum, stainless steel and alumina. Builds up smooth and thick coatings. Has been used for aluminum mold repairs. Air Temperature: 500C
Gun Pressure: 85-90 psi		  
Aluminum Oxide KSA-22460 400 grit aluminum oxide. This light grit blast is an excellent general blasting media, particularily for sensitive surfaces and then substrates. This is not a high purity oxide and may not be suitable for applications with high sensitivity to purity (e.g. corrosion protection coatings) Air Temperature: 0 - 500C
Gun Pressure: 60 - 100 psi		  
Aluminum Oxide KSA-22456 80 grit aluminum oxide. This medium coarse grit blast is an excellent general blasting media for preparing most surfaces. This is not a high purity oxide and may not be suitable for applications with high sensitivity to purity (e.g. corrosion protection coatings) Air Temperature: 0 - 500C
Gun Pressure: 60 - 100 psi		  
Copper KSF-C075 A general purpose copper blend including aluminum and alumina particles. Bright color and very good deposition. Smooth and thick coatings can be produced. Good machinability and good bonding.
Hardness: 75-80 HRB		 Air Temperature: 500C
Gun Pressure: 85-110 psi		  
Copper KSF-C22843 Pure copper that can produce highly conductive and smooth coatings. Thick deposits (over 3 mm) may be difficult to produce.
Deposition Efficiency: 25% or greater		 Air Temperature: 450C
Gun Pressure: 85-90 psi		 A rough surface emerges as the coating gets thicker. Try reducing material feed rate to avoid roughness.
Nickel KSF-N22289 Pure nickel powder. Low deposition efficiency - See blended nickel powders for powders with specific performance characteristics. Air Temperature: 500 - 550C
Gun Pressure: 90 - 145 psi		  
Nickel KSF-N056-1 A general purpose nickel blend recommended for cast iron repair.
Hardness: up to 80 HRB		 Air Temperature: 500 - 550C
Gun Pressure: 90 - 145 psi		  
Nickel KSF-N039 A very good nickel blend choice with high hardness for applications needing a more durable coating. Can be built up to thick coatings and has a smooth spray finish.
Hardness up to 25 Rc		 Air Temperature: 500 - 550C
Gun Pressure: 90 - 145 psi		  
Nickel KSF-N006 A good general purpose nickel/oxide blend. An economical choice.
Hardness: up to 288 HRB		 Air Temperature: 450 - 550C
Gun Pressure: 90 - 145 psi		  
Stainless Steel KSF-S008 Stainless steel 316 blended with aluminum. Hardness is up to 3 times greater than a pure aluminum deposit.
Hardness: 70-75 HRB		 Air Temperature: 475C Max.
Gun Pressure: 85-90 psi		 If nozzle clogging occurs, reduce temperature.
Zinc KSF-Z23093 Pure zinc with excellent deposition, smooth coatings and good bonding. Air Temperature: No Data
Gun Pressure: 85-90 psi		 Zinc tends to be very sticky and nozzle clogging could occur at excessive temperatures. Reduce temperature to avoid clogging.
Zinc KSF-Z022 Blend of zinc and copper. Very thick and smooth coatings can be produced. Has been used to repair kirksite tools.
Hardness: up to 65 HRB		 Air Temperature: 450C
Gun Pressure: 85-90 psi
