wear-resistant copper alloy
UH13
- Corrosion resistance and wear resistance
It is a special high-strength brass bar with improved strength and wear resistance by solid solution strengthening and precipitation strengthening of Mn-Si intermetallic compounds.
Positioning map
Demand for higher-strength, more wear-resistant copper alloys is increasing as machinery and equipment continue to operate at higher speeds and performance levels. In addition, good machinability during production is also required. UH 13 is a lead-free copper alloy that combines high strength with excellent machinability, and can serve as a cost-effective alternative to stainless steel and bronze for components, contributing to overall cost reduction.
Main features
UH13 is characterized by high strength and excellent wear resistance.
