Product Description
Tungsten carbide button are a widely used tool in the mining industry, essential to help extract and break rocks. They are produced using high-quality material and advanced technology, ensuring their durability and high performance. As a manufacturer in China, we offer high-quality Carbide Mining Buttons to merchants all over the world at a competitive price.
Our advantage of making tungsten carbide button bits is that we are using HIP sintering for minimizing the porosity of carbide blank for increasing the transverse ruputure strenth (TRS). It is very suitable for high quality requirment for making carbide bottons to be ued in high and medium pressure DTH Drilling. As its unique working performance, tungsten carbide button bits are widely applied to oil filed drilling and snow removal, snow plough machines or equipments.
Tungsten carbide button characteristics
1. Cemented carbide/tungsten/spherical button
2. Wearing resistance good
3. Best suited to hard rock
4. Abrasive to very abrasive
Application:
Carbide Buttons are made from Tungsten carbide powder and cobalt powder, it has very high hardness, toughness and were resistance, wildly used in mining, excavating and construction tools. DTH drill bits industry need huge quantity carbide buttons, which are pressed into face and side of the DTH bits head.
