Advantages of Tungsten Carbide Standard Parts
Hardness
Tungsten carbide is one of the hardest materials known, ranking 9-9.5 on the mohs hardness scale. Only diamond ranks higher with a hardness of 10. The extreme hardness of tungsten carbide comes from tungsten metal particles being bonded with carbon atoms in a process called sintering. This hardness makes tungsten carbide highly scratch resistant and able to maintain its shape and finish even under extreme pressure and friction. Tungsten carbide's hardness allows it to be used in applications like cutting tools, drill bits, and wear-resistant parts.
Wear Resistance
The hardness and strength of tungsten carbide give it excellent wear resistance properties. While other metals like gold and silver lose mass and show signs of wear over time, tungsten carbide is able to maintain its original shape and finish even after years of frequent use and exposure to the elements. The durable crystalline structure of tungsten carbide prevents the loss of material through abrasion or corrosion. This makes tungsten carbide ideal for jewelry and accessories that need to retain their original polished look despite being worn every day. Tungsten carbide rings and watches do not show scratches, dents or other signs of aging like other metals.
Strength
In addition to hardness, tungsten carbide has very high strength-to-weight ratio, meaning it is incredibly strong for its weight. The unique crystalline structure formed by sintering tungsten and carbon particles imparts tremendous compressive strength that allows tungsten carbide to withstand high impacts and crushing forces without cracking. This strength makes tungsten carbide suitable for applications requiring toughness and durability like mining and construction tools as well as everyday accessories. Tungsten carbide jewelry can withstand accidental drops and impacts that would permanently damage rings or watches made of softer precious metals. Everyday activities like exercising, gardening and outdoor adventures are no match for tungsten carbide's strength.

The working principle of tungsten carbide is fundamentally based on its unique microstructure and properties. Tungsten carbide (wc) is a hard material that is typically bonded with a metallic binder, usually cobalt (co), through a process called sintering. This process involves heating the powdered mixture of tungsten carbide and cobalt to a high temperature, just below the melting point of the binder, allowing the binder to melt and fill the spaces between the tungsten carbide particles. As the material cools, the tungsten carbide grains are held in place by the hardened binder, creating a dense, hard composite material.
The high hardness of tungsten carbide stems from the strong covalent bonds between tungsten and carbon atoms, making it extremely resistant to wear and abrasion. The metallic binder, on the other hand, provides toughness and allows the material to withstand impact without shattering. This combination of high hardness and toughness is what enables tungsten carbide tools and components to perform exceptionally well in demanding industrial applications, such as cutting, drilling, and machining of hard materials, where they can maintain their shape and sharpness under high stress and heat.
Application of Tungsten Carbide Standard Parts
Construction
Construction requires the use of tools that are both powerful and durable in order to deal with the materials that most constructions are built of. It takes a very strong and resilient blade or drill bit, such those composed of tungsten carbide, to cut through tough materials like cement and asphalt. Due to its nearly indestructible nature, tungsten carbide is frequently used in construction products like drill bits and saws.
Ammunition
Tungsten carbide is widely employed in armor-piercing ammunition, either as a monolithic sintered type or as a tungsten carbide cobalt composite, especially when depleted uranium is unavailable or politically unpalatable. Tungsten carbide was only utilized to make machine tools and a small number of projectiles. It is an effective penetrator due to its great hardness and density.
Alloys
Alloys are made by combining metals with other metals or elements to produce electronics, building materials, industrial gears, and even aviation equipment. These alloys are created to have the particular characteristics, like as strength or heat resistance, required for each unique product and its usage. For building supplies and equipment, tungsten carbide alloys are a particularly well-liked option. These alloys are produced using around 17% of the total tungsten carbide utilized today.
Jewelry
A new and intriguing use for tungsten carbide is in the jewelry industry. Tungsten carbide jewelry may be as beautiful as any other item you might ordinarily wear if it is cut, produced, and polished properly. Tungsten carbide is a more affordable alternative for jewelry than the gold or silver we’re used to paying for and is also recognized for its remarkable and superior scratch resistance. Due to its durability, this metal is now ruling the market and is frequently used to make earrings, necklaces, and rings.
Surgical Instruments
Many of the prospective applications for tungsten carbide are still being found, and one of these new applications is in the medical arena. Tungsten carbide is frequently used to make surgical equipment because it improves performance and is corrosion-resistant. It increases the durability and strength of the surgical instruments. The surgical sector benefits from the features of tungsten carbide, such as its ability to be sharpened while preserving hardness.
Powder preparation
Powder preparation usually starts from the apt. The apt (ammonium para-tungstate) is calcined into tungsten oxide under high temperatures. Subsequently, the oxide is reduced to tungsten metal in a hydrogen atmosphere. The metal powder is then mixed with carbon and carburized under an inert atmosphere at high temperatures.
The tungsten carbide is intensely mixed with the binder metal cobalt, nickel, or iron, various grain growth inhibitors, and materials, which promote compaction, by wet grinding so that a homogeneous suspension is created. Afterward, the suspension is dried in a spray tower to produce a granulate with good flow characteristics. This granulate represents the basis for all forming processes.
Metal forming
The objective of the forming process is to obtain a near-net shape sample. Pressing is normally carried out at room temperature with pressures reaching up to several tons per square centimeter.
There are several ways of pressing blanks:
During isostatic cold pressing the powder is filled into an elastic flexible hose and pressed into a compacted form through high liquid pressure. The powder blocks which are produced in this way can then be processed mechanically. This method is mainly for producing tungsten carbide rods.
Extrusion pressing is mainly used with dies. Pressing can be used for manufacturing tungsten carbide inserts, tungsten carbide buttons, tungsten carbide tips, and so on.
Metal injection molding is a process used to produce more complex forms which cannot be produced by direct pressing. The paste preparation is similar to the extrusion process.
During pressing, the forming agency will be added for better compacting and must be evaporated before sintering.
Machining
For some tungsten carbide products in special shapes, this process is for better shaping. And all common machining methods like milling, cutting, drilling, or turning may be applied.
Sintering
The sintering process converts the blank into a homogeneous and dense carbide with a high level of hardness. The volume is reduced by up to 50 % during this process. Generally speaking, sintering always has four stages.
●Removal of the molding agent and pre-burning stage
In this process, the temperature should be increased gradually, and this stage happens below 1800℃. As the temperature increases, the moisture, gas, and residual solvent in the pressed tungsten carbide gradually evaporate. The molding agent will increase the carbon content of the sintering cemented carbide. In different sintering, the increase of carbide content is different. The contact stress between powder particles is also gradually eliminated during the increase in temperature.
●Solid-phase sintering stage
As the temperature is slowly increasing, the sintering continues. This stage occurs between 1800℃ and the eutectic temperature. The so-called eutectic temperature refers to the lowest temperature at which a liquid can exist in this system. This stage will continue based on the last stage. The plastic flow increases and the sintered body shrinks significantly. At this moment, the volume of tungsten carbide shrinks obviously.
●Liquid phase sintering stage
At this stage, the temperature rises until it reaches the highest temperature in the sintering process, the sintering temperature. When the liquid phase appears on the tungsten carbide, shrinkage completes quickly. Due to the surface tension of the liquid phase, the powder particles approach each other, and the pores in the particles are gradually filled with the liquid phase.
●Cooling stage
After sintering, the cemented carbide can be removed from the sintering furnace and cooled to room temperature. Some factories will use the waste heat in the sintering furnace for new thermal utilization. At this point, as the temperature drops, the final microstructure of the alloy is formed.
