2. 50%-70% Tungsten Carbide Content

Products in the 50%-70% tungsten carbide range provide a versatile middle ground, combining moderate conductivity with improved mechanical strength and erosion resistance. These composites are ideal for medium-duty applications, resisting welding under arcing conditions while maintaining consistent performance over cycles.

Market Insight: Demand for this category is steadily increasing in industrial and commercial settings. For example, it’s widely adopted in molded case circuit breakers where balanced properties are essential for safety and longevity.
Trend: With the growth of automation in manufacturing, these contacts are gaining traction in Asia-Pacific markets, supporting the expansion of electrical panels in emerging economies focused on infrastructure development.

3. Above 70% Tungsten Carbide Content

High tungsten carbide content above 70% delivers exceptional hardness and arc quenching capabilities, suited for heavy-duty, high-interruption applications. These contacts excel in environments with severe arcing, offering superior resistance to material transfer and pitting.

Market Insight: Above 70% carbide contacts are the fastest-growing product segment, particularly in high-voltage systems. They are critical for applications demanding maximum durability, such as in power distribution and protection relays.
Trend: As global electrification accelerates, manufacturers are scaling production of these high-content variants to meet demands from renewable energy installations and electric vehicle charging infrastructure.
