Backing Bonds for Laser Welding

Our backing bonds have been developed especially for laser-welding diamond tools.
They distinguish themselves by a high weld strength and a very precise welding seam.

These products provide a wide range of bonds for different sintering temperatures and with different compositions. We thus give you the possibility of selecting the optimum backing bond for every matrix powder.

  • attractive price
  • very good weld strength
  • big sintering range
  • sold in quantities between 1 kg and 50 kg
  • very precise welding seam
