Tungsten Carbide Wear Parts Carbide Wire Guide Dies / Tube Guide For Extrusion Carbide wire guide is made of tungsten carbide for its extremely hard and wear-resistant features, with sophisticated equipment for precision grinding and polishing, coupled with advanced production and processing technology, the inner and the outer diameter of the hole and tolerance R at less than 0.01mm, the surface roughness over the trough reached Ra 0.025 and above, it requires high hardness, smooth surface in use to reduce injury and other enameled wire. Selected carbide grades are YG6X, YG6, YG8, YG15 and so on. Its service life is 10 times than steel wheels. Introduction of Carbide Wire Guides: High hardness (86 ~ 93HRA, equivalent to 69 ~ 81HRC); Hot hardness (up to 900 ~ 1000 �°C, keeping 60HRC); Good wear resistance There are V-groove, R-groove, U-groove trough over other. V-groove with 90, 110 , 120 , and other specifications, R-groov ranging from R0.2 to R25. Diameter 500mm available.
