Description
Boron carbide powder F280 F320 F360 for metal coat
F280 F320 F360 boron carbide (B4C) powder is a high-performance hard ceramic filler specially developed for metal surface coating modification. Produced through high-temperature smelting, precise crushing and strict F-standard grading, this powder features uniform particle size distribution, high purity and stable mechanical properties. As one of the hardest industrial materials with ultra-high microhardness, it far exceeds conventional silicon carbide and alumina abrasives, making it an ideal functional additive for enhancing metal protective coatings.
Tailored for metal coating systems, F280 F320 F360 medium-fine grain size achieves a perfect balance between filling compactness and surface flatness. Uniformly dispersed in epoxy, polyurethane and anti-corrosion coating resins, it effectively fills microscopic pores of the coating layer, significantly improving overall density, bonding strength and wear resistance. It solves common defects of ordinary metal coatings such as easy abrasion, poor scratch resistance and short service life under harsh working conditions.
This boron carbide powder possesses excellent high-temperature resistance, acid and alkali corrosion resistance, and strong antioxidant capacity. It maintains stable physical and chemical properties under high-temperature friction, humid corrosion and long-term outdoor exposure. The unique self-lubricating and anti-wear characteristics greatly reduce surface friction coefficient of metal workpieces, effectively resisting mechanical impact, particle erosion and chemical erosion.
With low impurity content and outstanding compatibility with various coating substrates, F280 boron carbide powder avoids agglomeration and coating cracking. It is widely applied in wear-resistant and anti-corrosion coating reinforcement for mechanical equipment, steel structures, automotive metal parts and engineering components, delivering durable protection and effectively lowering overall maintenance costs.
