DAPTM-AM Series - Metal Powders for 3D Printing -

High Thermal Conductivity Powders for Molds DAPTM-AM HTC45

DAPTM-AM HTC45 is SKD61-based powder adjusted to a composition suitable for additive manufacturing of die-casting molds.

Hardness suitable for die-casting molds can be obtained by just directed energy deposition.

Feature

• DAPTM-AM HTC45 has spherical shape, low oxygen content and high flowability produced by gas atomization.
• DAPTM-AM HTC45 is cobalt free material, the same as SKD61.
• The hardness suitable for die-casting molds of 45-48HRC can be obtained by directed energy deposition, and no post-heat treatment is required.
• The high thermal conductivity of the overlay portion enhances the cooling effect of the mold.
  In addition, thermal stress can be reduced and heat checking can be effectively suppressed.

Major application

• Repair of die casting molds

for As-3D printed DAPTM-AM HTC 45

DAPTM-AM HTC 45 has a higher hardness than maraging steels after overlay weling.
Its high thermal conductivity suppresses heat checking.
