Applications |
·Angular shape, high hardness. ·For PTA application with blending Ni or Nickel base alloy powder ·Good wear resistant for oil drilling tool mineral tool. ·Used for producing WC base alloy powder |
·Spherical shape, highest hardness. ·For PTA application with blending Ni or Nickel base alloy powder ·Good wear resistant for oil drilling tool mineral tool. ·Generate more dense coating compared with FTC, and with better hardness and wear protection |
·Angular shape, single crystal organization. ·Good thermal stabilization, higher thermal conductivity. ·No hole and loose structure, dense, good corrosion resistant ·Good hardfacing material for diamond drill and metallurgy industry. |
