What Material Is Best For Bushings?
Oct 27, 2026| 1.Copper-based (Tin Bronze CuSn10, Most Versatile Preferred)
• Advantages: Low friction coefficient, excellent thermal conductivity, resistant to seizing, good break-in performance, corrosion resistance, low noise, high PV value limit, suitable for medium to high speeds, small to medium loads, frequent start-stop cycles, and inconvenient oil replenishment in oil-impregnated bushings using powder metallurgy technology ..
• Disadvantage: High price
• Application: motors, fans, office equipment, precision transmission
2.Iron-Copper Base Fe-Cu-C (Cost Performance King)
• Advantages: Higher strength than pure copper-based materials, significantly lower cost than copper-based materials, acceptable wear resistance, and a balance between load-bearing and self-lubrication
• Disadvantages: Poor thermal conductivity and anti-galling performance compared to pure copper-based materials, prone to rust, requiring anti-corrosion treatment
• Applicaion: household appliances, automotive wipers, low-speed medium-load structural components
3.Iron based Fe-C (cheapest)
• Advantages: High strength, lowest cost, thermal expansion coefficient close to steel shaft
• Disadvantages: High friction coefficient, easy to rust, poor bite resistance, use with caution at high speeds
• Applicaion: low-speed heavy-duty, intermittent work, cost sensitive models
4.Stainless steel powder metallurgy (304/316)
• Advantages: Strong corrosion resistance, suitable for humid, water, food, and pharmaceutical environments
• Disadvantages: difficult pore control, poor self-lubricating performance, high cost, usually combined with solid lubrication (graphite/PTFE), rarely used for ordinary oil containing bushings
