On October 17, 2025, Hunan Bohou New Materials Co., Ltd. launched Fe10W, a new alloy material that provides a domestically produced solution for upgrading wear-resistant components in construction machinery, effectively addressing the industry’s longstanding pain points of traditional materials being “hard yet brittle” and “tough but not wear-resistant.”
In extreme operating conditions such as mining and infrastructure projects, components like excavator buckets often need to be replaced frequently due to wear, leading to skyrocketing maintenance costs. The Fe10W alloy achieves a perfect balance between hardness and toughness through optimized composition and microstructural design: its measured hardness reaches 63–68 HRC, comparable to that of high-grade tool steels; its impact resistance exceeds that of nickel-based tungsten carbide by more than ten times, and its microstructure is fine and uniform. Combined with advanced PTA surfacing technology, this alloy can form a smooth, dense coating that ensures long-lasting and stable wear resistance.
Practical application data show that buckets made from this material have several times longer service life in mining and rock-crushing operations, significantly reducing equipment downtime during sand and soil excavation, and markedly lowering overall maintenance costs. Industry insiders point out that this breakthrough marks China’s heavy industry sector reaching an internationally advanced level in wear-resistant materials and holds the potential to reshape industry standards.

The Lanzhou Institute of Chemistry, Chinese Academy of Sciences, has achieved a breakthrough in high-temperature wear-resistant technology; a new type of ceramic achieves “negative wear.”

Wodun wear-resistant pipe provides protection for a 30,000-ton dredger, overcoming the challenge of deep-sea abrasion.

An innovative technology aimed at addressing the challenge of wear in critical industrial equipment—the low-friction, ultra-wear-resistant nanodiamond coating material—has recently achieved successful engineering demonstration applications.
