Phosphor Bronze Disk (Cu94/Sn6)

Phosphor Bronze Disk (Cu94/Sn6) offers a robust balance of wear resistance, elasticity, and corrosion protection in a circular precision-cut form. The tin-phosphorus alloy structure ensures excellent load-bearing capability and long-term dimensional stability, making it suitable for use in mechanical linkages, bearing faces, and electrical contact interfaces. The disk geometry enables seamless installation into rotary mechanisms, test assemblies, and compact mechanical systems. Common industrial uses include thrust washers, gear spacers, and rotating contact plates in aerospace, marine, and electronics sectors. In research, this form is employed in fatigue characterization, corrosion environment simulations, and prototype testing for precision mechanical components. The combination of material resilience, dimensional accuracy, and corrosion resistance ensures high reliability in demanding operational contexts.
