合金层硬度：HB30~40
JF20 high percentage of tin with aluminum alloy bushing
JF20 high percentage of tin with aluminum alloy bushing is backing on low carbon steel, pressed with AlSn20Cu as liner. It has fairly good performance in anti-fatigue and good load capacity, anti-corrosion and smooth sliding movement. 
It usually used as engine bearing with middle or low power, air compressor bushing. It is a good substitution for Babbit material.   
Liner material: AlSn20Cu 
Load capacity: 30N/mm2    
Temperature Max: 150℃ 
Liner hardness: HB30~40
