SHEET NON-FERROUS METALS 



789 



Alloy C Phosphor-Bronze Sheet. — The alloy C rolling series were 

 made from five bars of metal having the average composition shown 

 in Table VII. This material was rolled to all even hardness numbers 

 from 2 to 10 numbers hard, for all even B. & S. gage numbers from

Fig. 16— Relation of Tensile Strength to Percentage of Reduction by Rolling of 

 Alloy A Phosphor-Bronze Rolling Series. 



No. 14 to No. 36, inclusive. The physical properties of this material 

 are given in Table XVI. The Rockwell hardness-tensile strength 

 relationship is shown in Fig. 17 and the tensile strength-reduction 

 relationship is shown in Fig. 18. The physical requirements for alloy 

 C are given in Table XV and the chemical requirements in Table VI.
