Chemical composition of ASTM B584-C938

Can any body tell me please the chemical composition of the alloy "ASTM B584-C938".

Thanks for help..

Sherif,

ASTM B584 C938 is a "High Lead Tin Bronze." It was previously designated as ASTM B144-3D and has a "common" designation of 78-7-15. Needless to say the nominal composition is 78% Cu, 7% Sn and 15% Pb. The ASTM spec title is "Copper Alloy Sand Casting."

Hope this helps.

Hi,

I am working with LB5 casting( High leaded bronze) . Want to know, how to check the homogeneity of the casting..? i.e., I want to know whether the lead is spread evenly.
