Product Introduction

ND Wire Drawing Dies (Nature Diamond wire drawing dies), it’s die blank raw material diamond is la type diamond. These diamonds contain certain nitrogen impurities (0.1% order of magnitude), and these nitrogen impurities are combined into small aggregates.
With very high hardness and good thermal conductivity and photothermal properties, in the industrial field is widely used in conductor industry. Its physical properties are: density 3.515g/cm3; hardness: 1.25-10.76GPa.

Feature:

1. We select each natural diamond carefully to ensure the good quality of the die core, coupled with precise orientation when mounting

2. With special plastic polishing equipment and unique mold hole production process

3. It will ensure that each mold has precise size, perfect hole type, in the filament, ultra-fine wire or high-surface finish wire pull-out always has excellent performance.

Advantages:

1. High hardness and good wear resistance

2. High-efficiency, smoothness, and durability predicted

3. A wide range of grain and nib sizes

4. Perfect characteristics of crack-proof and good polishing of wire or tube surface

5. Fast delivery time at about 7-10 days after receiving your payments

Application

ND Wire Drawing Dies Application:

Recommended for drawing of all types of wire with high surface quality requirements: platinum-palladium wire, gold wire, silver wire, copper, aluminum, nickel, tinned copper, tungsten, copper-aluminum alloy and other non-ferrous metal wire.
