Tungsten
carbide is a hard material composed of a metal matrix composite
where carbide particles act as the aggregate and a
metallic binder serves as the matrix. It is one of the
most successful composite engineering materials ever
produced. Its unique combination of strength, hardness and
toughness satisfies the most demanding applications.
Tungsten carbide is used in machining tough materials such as cast iron
or steel, as well as in situations where other tools would wear away,
such as mining tools and wear parts. Most of the time,
carbide will leave a better finish on the part,and allow faster
machining. Carbide tools can also withstand higher temperatures than standard
high speed steel tools.
tungsten carbide coal cutting bits in various grades and shape:
1) Mushroom Shaped Tips
Soft rock formations, See the flowing figure and table for the shape, various types and dimensions of the Columnar.
2) Columnar Shaped Tips
Medium Hard and hard rock formations, see the flowing figure and table for the shape, various types and dimensions of the Columnar.
suitable for use in products like Down The Hole Drilling Bits, Tricon Rock
Roller Bits, Special bits required for underground cable laying, etc. We can
supply the coal cutting in ground and
tumbled finish which facilitates perfect fitting in shank.
Advantages of Tungsten carbide mining button bits for coal mining
1.High wear&impact resistance
2.Advanced equipment.
3.A long life time
4.High performance
5.We can make various tungsten carbide road tips with different grades,high quality, in nice price.
6.Element Six products are highly wear- and impact-resistant, thanks to their strength, hardness and toughness. Improving tool life, cost efficiency and productivity can be as simple as moving from steel towards synthetic diamond or tungsten carbide.
