Tungsten carbide is highly resistant to water. It does not rust or corrode when exposed to moisture, making it suitable for wet environments. This resistance comes from its chemical composition and dense atomic structure, which prevent water molecules from penetrating or reacting with the material. Whether used in cutting tools, industrial parts, or jewelry, tungsten carbide can safely encounter water without damage.
While tungsten carbide itself resists water, the binder metal—usually cobalt—can be vulnerable to corrosion if exposed to harsh chemicals or prolonged moisture. This could lead to slight surface discoloration or weakening over time, especially in industrial settings with acidic or salty water. However, under normal conditions like rain or sweat, tungsten carbide remains stable and unaffected.
In jewelry, tungsten carbide rings and accessories retain their shine and strength even after regular exposure to water, such as washing hands or showering. They do not tarnish or lose hardness. That said, exposure to chlorinated pool water or harsh cleaning agents should be minimized to protect the binder and maintain the ring’s appearance over the long term.
To keep tungsten carbide in top condition when exposed to moisture, follow these simple tips:
Clean Regularly: Use mild soap and warm water to clean tungsten carbide items. Avoid harsh chemicals or abrasive cleaners.
Dry Thoroughly: After exposure to water, dry items completely to prevent any buildup of moisture around the binder metal.
Avoid Chemicals: Limit contact with chlorinated water, bleach, or acidic substances that could corrode the binder.
Store Properly: When not in use, store tungsten carbide pieces in a dry place to reduce moisture exposure.
Inspect Periodically: Check industrial parts for signs of corrosion or wear, especially if used in wet or humid environments.
These practices help maintain tungsten carbide’s durability and appearance, ensuring it performs well over time even in wet conditions.
Tip: For industrial tools exposed to moisture, selecting tungsten carbide grades with higher binder corrosion resistance enhances longevity and reduces maintenance needs.

Finally, tungsten carbide rings maintain their shape and color. They won’t bend, warp, or tarnish easily, ensuring the ring looks great for a lifetime.
Although tungsten carbide is tough, proper care helps preserve its appearance:
Clean gently: Use mild soap and warm water. Avoid harsh chemicals or abrasive cleaners that could damage the binder metal.
Dry thoroughly: After cleaning or exposure to water, dry the ring completely to prevent moisture buildup.
Avoid harsh environments: Limit contact with chlorinated pools, bleach, or acidic substances. These can corrode the binder over time.
Store safely: Keep tungsten carbide jewelry in a soft pouch or separate compartment to avoid scratches from other pieces.
Handle with care: Though resistant to scratches, tungsten carbide can crack or shatter if dropped on hard surfaces or hit with strong force.
Following these simple steps ensures your tungsten carbide jewelry retains its shine and strength for years.
Tip: When buying tungsten carbide rings, choose reputable jewelers who offer warranties and accurate sizing, since rings cannot be resized after purchase due to the material’s hardness.
Tungsten carbide is a top choice for cutting tools and dies because of its incredible hardness and wear resistance. It keeps cutting edges sharp longer than steel, which means tools last much longer and maintain precision. Industries like automotive, aerospace, and metalworking rely on tungsten carbide inserts, end mills, and drill bits to machine tough materials efficiently.
For dies used in stamping, extrusion, and forming, tungsten carbide offers excellent durability. It withstands high pressure and abrasive wear, reducing downtime due to tool replacement. Compared to steel dies, tungsten carbide dies resist deformation and maintain dimensional accuracy, improving product quality.
One standout feature of tungsten carbide is its ability to keep hardness at high temperatures, often up to 1,000°C (1,832°F). This makes it ideal for applications involving heat, such as high-speed machining and metal cutting, where friction generates intense heat.
Unlike many metals that soften or lose strength under heat, tungsten carbide tools retain toughness and resist wear. This stability reduces tool failure and improves efficiency in processes like milling, drilling, and turning. It also lowers costs by extending tool life and minimizing production interruptions.
Mining and drilling industries depend heavily on tungsten carbide for parts exposed to extreme conditions. Drill bits, cutting tips, and wear plates made from tungsten carbide can cut through hard rock and abrasive materials without wearing down quickly.
Its toughness and hardness help equipment operate reliably in harsh environments, such as underground mines or oil fields. This durability reduces maintenance needs and downtime, boosting operational productivity. Tungsten carbide’s resistance to impact and abrasion extends the lifespan of mining tools, making it a cost-effective choice.
Tip: When selecting tungsten carbide for industrial tools, consider the specific binder content and grain size to balance hardness and toughness for your application’s demands.
Recycling tungsten carbide involves recovering valuable materials from used tools, inserts, and scrap parts. The process typically starts with collecting and sorting tungsten carbide scrap. Then, the scrap undergoes crushing or grinding to reduce size. Afterward, chemical or physical methods separate tungsten carbide grains from the cobalt binder and other metals.
One common method is the chemical recycling process, where the scrap is treated with acids or alkalis to dissolve the binder metal. This leaves behind pure tungsten carbide powder, which can be reused to manufacture new products. Another approach is thermal recycling, where scrap is heated to high temperatures to remove the binder, allowing tungsten carbide to be reclaimed.
Recycled tungsten carbide powder often matches the quality of virgin material. It can be mixed with fresh binder metal and sintered to create new tools or components. This closed-loop recycling reduces waste and conserves natural resources.
Recycling tungsten carbide offers significant environmental advantages. Mining tungsten ore consumes large amounts of energy and disrupts ecosystems. Recycling reduces the demand for new mining, helping preserve natural habitats and decrease pollution.
Energy savings from recycling are substantial. Producing tungsten carbide from recycled powder uses about 70% less energy than starting with raw ore. This reduction lowers greenhouse gas emissions and cuts operational costs.
Recycling also minimizes landfill waste. Tungsten carbide tools and parts last long but eventually wear out. Instead of discarding them, recycling turns waste into valuable raw material, promoting a circular economy.
By recycling, industries reduce reliance on tungsten imports, which often come from geopolitically sensitive regions. This supports local manufacturing and supply chain stability.
Economically, tungsten carbide recycling is highly beneficial. Scrap carbide holds significant value, often selling between $5 to $10 per pound (example figures). This makes recycling a profitable venture for manufacturers and scrap dealers.
Recycling reduces raw material costs for manufacturers. Using recycled tungsten carbide powder lowers expenses compared to purchasing virgin material. This cost saving can improve competitiveness and profitability.
Additionally, recycling supports job creation in collection, processing, and resale sectors. It also fosters innovation in recycling technologies and waste management practices.
For businesses holding tungsten carbide scrap, partnering with experienced recyclers ensures fair pricing and efficient processing. This turns end-of-life tools and scrap into revenue streams rather than disposal costs.
Tip: Partner with certified tungsten carbide recyclers who provide transparent grading and fair pricing to maximize the economic and environmental benefits of your scrap materials.
Despite tungsten carbide’s outstanding hardness and wear resistance, it has a notable downside: brittleness. Unlike metals such as steel or titanium, tungsten carbide does not bend or deform under heavy impact. Instead, it can crack or shatter if dropped or struck with sufficient force. This brittleness results from its ceramic-like crystal structure, which is very hard but lacks ductility.
In practical terms, this means tungsten carbide rings or tools can break when subjected to sharp impacts or sudden shocks. For example, a tungsten carbide ring dropped onto a hard surface may chip or crack, unlike a gold ring that would simply dent. In industrial settings, improper handling or accidental collisions can cause tungsten carbide components to fracture, leading to downtime or costly replacements.
Manufacturers try to balance hardness and toughness by adjusting the cobalt binder content. More binder improves impact resistance but reduces hardness. Less binder increases hardness but makes the material more brittle. Finding the right balance depends on the application’s demands.
Tungsten carbide is more expensive than many common metals, primarily due to raw material costs and complex manufacturing processes. The powder metallurgy method involves precise mixing, pressing, and sintering at high temperatures, which adds to production expenses.
For consumers, tungsten carbide jewelry offers great value for its durability and scratch resistance, but initial costs are higher than stainless steel or titanium alternatives. In industrial applications, the long tool life often justifies the upfront investment, but budget constraints can limit its use in some projects.
Additionally, tungsten carbide’s brittleness may lead to unexpected replacement costs if the material breaks under impact. This risk sometimes requires extra care in handling or additional protective measures, indirectly increasing overall expenses.
Machining tungsten carbide is challenging due to its extreme hardness. Conventional metalworking tools cannot easily cut or shape it. Specialized equipment with diamond-coated or cubic boron nitride (CBN) tools is necessary for grinding and finishing tungsten carbide parts.
This difficulty raises production time and costs, especially for complex shapes or custom designs. In jewelry, the hardness limits resizing options; tungsten carbide rings cannot be resized by stretching or compressing. Instead, customers must reorder the correct size or use sizing beads.
In industrial manufacturing, machining limitations restrict design flexibility. Complex geometries or intricate details require advanced techniques like electrical discharge machining (EDM) or laser cutting. These processes add to tooling expenses and production lead times.
Tip: When selecting tungsten carbide for your application, weigh the trade-offs between hardness and brittleness carefully, and plan for machining challenges to avoid costly surprises.
