Description

The melting of gunmetal under the oxidising atmosphere decreases the hydrogen content and improves the mechanical properties of gunmetal. <br>  The auther recomends the following operations. <br>(1) Melt the cathode cupper in the crucible in oxidising atmosphere without flux up to 1,200°C or 1,250°C. <br>(2) Deoxidise the melt with 0.2% phosphor-cupper. <br>(3) Cover the surface of the melt with common salt of 0.2%. <br>(4) Add zinc. <br>(5) Tin followed. <br>(6) Draw out the crucible at about 1,300°C. <br>  By this process, the mechanical properties are impnoved to the following degree, the tensile strength 8%, the elongation 20%, the specific gravity 1.7% etc.
