Coating Materials
PTA&Laser Clad Powder
After nearly 10 years of development, we have developed a variety of PTA and laser cladding powders. These powders involve various process techniques such as atomization, mixing, spheroidization, and more.
 
Basically, PTA and laser cladding powders are divided into iron-based alloy powders, such as stainless steel, nickel-based alloy powders, cobalt-based alloy powders (Stellited series) and CWC blended powders. CWC blend powders play an important role in hard surface processing in PTA technology.
