Abstract
PURPOSE: To enhance the mechanical properties, plastic workability and corrosion resistance of a Cu-Sn-P alloy by adding a specified amt. of Zn to the alloy in melting to control consumption of the Sn and P and increase the deoxidizing effect of the P.
CONSTITUTION: In refining a phosphor bronze type Cu alloy consisting of Sn 0.5W9%, P 0.03W0.35% and the balance Cu, Cu is first melted in the air, and Zn is added in the form of a Cu-Zn mother alloy to allow Zn 0.05W1.0% to be contained. Sn and P are then added in the form of a Cu-Sn mother alloy and a Cu-P mother alloy to allow Sn 0.5W9% and P 0.03W0.35% to be contained, and the resulting molten alloy is cast. By adding the Zn degassing and deoxidation are performed to prevent oxidation consumption of the Sn and P added thereafter and to enhance the deoxidizing effect of the P. Thus, an ingot giving an end product with little cracks is obtd. while maintaining superior mechanical properties, plastic workability and corrosion resistance.
