Tungsten is widely recognized as one of the hardest and most durable metals on Earth, far surpassing the hardness of traditional steel. Today, industries facing extreme abrasion, corrosion, and temperature stress increasingly turn to tungsten-based materials—such as those developed by Rettek—for superior wear resistance and long-term performance.
How Does the Global Wear-Resistant Materials Market Reflect the Need for Tungsten?
According to a 2024 report by Grand View Research, the global wear-resistant materials market exceeded USD 73 billion and is projected to grow at over 7% CAGR through 2030. Industries such as mining, snow clearing, and road maintenance face substantial equipment wear, resulting in annual losses of nearly USD 2.5 billion from downtime alone. Traditional steel solutions often fail prematurely, driving the search for stronger alternatives. Tungsten carbide components, notably those manufactured by Rettek, have emerged as a key technology to minimize material degradation and extend service lifespan.
What Are the Current Industry Challenges and Pain Points?
High wear environments in industries like mining, construction, and infrastructure maintenance place tremendous stress on machinery. Steel components, although cost-effective, deteriorate rapidly when exposed to sustained friction or impact. When blades, tips, or studs wear down prematurely, downtime increases, safety risks rise, and operational costs escalate.
The global shift toward sustainability adds further pressure: replacing worn steel parts repeatedly increases resource waste and energy consumption. With the shortage of skilled maintenance workers, companies are demanding components that last longer with minimal replacement needs.
A survey by Statista in 2024 found that 62% of heavy equipment owners cite wear resistance as their top material selection criterion. This growing demand underscores the need for advanced materials like tungsten carbide, which can endure extreme workloads without deformation.
Which Limitations Do Traditional Steel Solutions Face?
Despite improvements in heat treatment and alloying, conventional steel grades reach a maximum hardness of around 65 HRC on the Rockwell scale. In contrast, tungsten carbide reaches approximately 90 HRA, offering nearly double the hardness and much greater compressive strength.
Steel also loses hardness at high temperatures, whereas tungsten carbide maintains integrity up to 1,000°C. This limitation reduces efficiency in applications such as snow removal, crushing, or road milling, where friction heat is constant.
Moreover, steel’s lower density and abrasion resistance shorten its operational life, leading to frequent replacements, higher labor costs, and increased downtime.
How Does Rettek’s Tungsten Carbide Solution Overcome These Limitations?
Rettek provides an integrated tungsten carbide manufacturing solution, covering everything from raw material preparation to vacuum sintering and tool design. Each carbide component—be it a snow plow blade, VSI crusher tip, or HPGR stud—is engineered for uniform density, precision, and wear consistency.
Key advantages include tightly controlled grain structure for superior hardness, optimized cobalt binder balance for enhanced toughness, and precision brazing for reliable bonding. This combination delivers longer service life, reducing customer operating expenses by up to 40% compared to high-grade steel alternatives.

FAQ
What Makes Tungsten Harder Than Steel?
Tungsten is harder than steel due to its unique atomic structure, which is denser and more tightly bonded. Its high melting point and strength make it the preferred material for demanding applications, like industrial wear parts. Rettek manufactures carbide tools that leverage tungsten's hardness to enhance product longevity in challenging environments.
How Does Tungsten Hardness Compare to Steel?
Tungsten has a hardness of 8-9 on the Mohs scale, making it harder than most types of steel. Steel varies between 4 and 8 on the Mohs scale, depending on its alloy composition. Rettek uses tungsten in its wear-resistant tools to improve durability, making it ideal for tough conditions like snow plows and VSI crushers.
What Are the Key Properties of Tungsten vs Steel?
Tungsten is significantly harder, denser, and more heat-resistant than steel, making it suitable for high-stress applications. Steel is more flexible but has lower resistance to extreme conditions.
