Nickel Powder Mixed with Cast Tungsten Carbide (PTA)
Ni60-based PTA hardfacing powder loaded with cast tungsten carbide for extreme abrasion.
This Ni60AA nickel-based PTA hardfacing powder contains evenly distributed cast tungsten carbide particles, with standard carbide ratios of 60%, 65% and customizable options.
Well-graded powder offers great flowability and stable feeding for all mainstream PTA equipment. Minimal carbide loss and good alloy wettability produce dense, crack-free hardfacing layers with adjustable thickness for batch surfacing or local part repair.
The coating combines carbides superior abrasion/erosion resistance and nickel matrixs toughness, corrosion & high-temperature oxidation resistance, performing reliably under heavy wear and moderate impact to lengthen component service life.
Suitable for mining, construction, oil, agricultural and power machinery, it strengthens and restores worn parts including conveyor blades, bucket teeth, crusher hammers and fan impellers to lower maintenance expenses.

How to Specify & Apply
Identify the Service Envelope
Determine the dominant wear mode (abrasion, erosion, adhesion, corrosion, oxidation), operating temperature and impact load. This narrows the grade selection to 2-3 candidates.
Match the Process
Each grade is validated for specific deposition processes. The "Application Process" field above shows HVOF, HVAF, APS, PTA, LMD, OFS or CAW compatibility.
Choose the Particle Size
Particle size controls deposit density and surface finish. Fine cuts (15-30um) for thin dense coatings; coarser cuts (45-90um) for thick build-up and high deposition rate.
Request a Sample
Most grades ship with a 1-2 kg sample for in-house process qualification. Our engineers will support parameter development on your equipment.
