The CVD wire-drawing die mold core is 100% of the diamond growth form in the oven, no additives and adhesive, it has the very high abrasion ratio, wear-resisting performance is good, high smoothness, wear uniform, etc. Because the CVD wire-drawing die temperature resistant up to 1000 ° C to 1200 ° C, the most ideal products is hot tungsten molybdenum wire. Specification range 0.06mm-2.00mm.
