HPHT Diamond Die Blanks (111)
Moresuperhard provides large diameter MCD (Monocrystalline Diamond) die blanks for wire drawing and other precision applications. Compared with regular sizes, large diameter die blanks present unique manufacturing challenges that only a few manufacturers worldwide can overcome.
Material: High-purity monocrystalline diamond
Orientation: <111>
Available Sizes: Up to Φ2.0 mm

Tungsten wire
Semiconductor bonding wires (gold wires, copper wires, and aluminum wires)
Medical wires
Stainless steel wires
Copper wires
Cutting wires
Special alloy wires
Precious metal wires Various other non-ferrous or ferrous metal wires
Large diameter stability: Excellent crystal uniformity, fewer internal defects.
Superior mechanical strength: High hardness and wear resistance ensure extended die life.
High surface finish: Capable of producing ultra-smooth wire surfaces.
Customizable: Dimensions available upon request.
111-facet synthetic single-crystal diamond is used as the die core, ensuring the produced dies have precise positioning and stable performance.
Extremely high hardness and wear resistance guarantee a long service life of the dies.
Single-crystal diamond has excellent heat dissipation performance, making it suitable for high-temperature processing technologies.
Single-crystal diamond is artificially synthesized, so its quality and consistency are guaranteed.
The die hole has an extremely high surface finish and low friction.
