Hard alloy, commonly referred to as tungsten steel in everyday language, is widely recognized for its application in the cutting edges of saw blades.  This material primarily consists of tungsten carbide and titanium carbide powders, with cobalt or nickel serving as binding agents.  It is manufactured into desired shapes through a sintering process.

The production of cemented carbide involves several key steps:

▼

The production process has,

1. Flour milling

Process the raw materials into powder form

2. Mixing materials

Mix the powder with the binder in a certain proportion

3. Forming

The mixed materials are then placed in the mold and pressed into the desired shape. Some are pressed into large pieces and then cut into small ones.

4.  Sintering

Sintering represents the most critical stage in the manufacturing process, significantly influencing the final quality of the cemented carbide.  Temperature and duration parameters are strictly controlled according to specific application requirements.

5.  Post-processing

Following sintering, the material undergoes additional machining or finishing operations tailored to meet product specifications.

Among industrially prevalent materials, cemented carbide ranks second in terms of hardness—surpassed only by diamond and followed by ceramic.  It should be noted that this ranking pertains specifically to conventional industrial materials;  ongoing advancements in materials science continue to yield novel substances, some of which exhibit hardness exceeding that of diamond.
