K10 K40 Tungsten Steel Bar For Cutting Tools In Processing Industry
Tungsten Steel Bar is mainly made of tungsten carbide and
cobalt alloy powder through metallurgical mixing, crushing, ball
milling, pressing and sintering. The main components are WC and Co.
The content of tungsten carbide and Co in tungsten steel bar of
different purposes is different, and it has a wide range of uses.
In a wide range, cemented carbide has good hardness and toughness,
has become the most widely used cemented carbide material, and is
widely used in engineering and tool products.
Feature of Tungsten Steel Bar
1. Using low-pressure sintering technology, the quality is stable
and reliable: the maximum sintering pressure can reach 100kg / F,
effectively eliminate the internal pores of the alloy, and obtain
high hardness and high strength blanks with good compactness.
Advanced temperature control system can effectively reduce quality
fluctuation.
2. The overpressure automatic pressure relief extrusion equipment
can produce various types of bars: the full-automatic extrusion
equipment imported from Germany can adjust the pressure according
to different requirements, which is conducive to the production of
different types of bars.
3. High precision finish grinding of bar can achieve mirror effect:
the CNC grinder is adopted, with the highest polishing rate, which
can quickly remove the damaged layer during polishing, improve the
surface finish, and achieve the mirror effect at the highest.
Precision of fine grinding rod: diameter tolerance D ≤± 0.03,
length tolerance L ≤± 0.5.

Application of Tungsten Carbide Bar
Tungsten steel bar is mainly used to make various metal and
non-metal cutting tools, such as PCB micro drill, drill bit, end
mill, reamer, etc. it is used to process aluminum alloy, stainless
steel, heat-resistant alloy steel, nodular cast iron, nickel base
and titanium alloy, non-ferrous metal and other products. Tungsten
steel bars are also widely used in stamping tools and
wear-resistant tools, such as plug-ins of various shapes, silicon
steel sheets and cold-rolled plates, punches, thimbles and punching
needles of stainless steel.
