Cadmium ever in copper phosphorus brazing rods?

Just wondering if cadmium has ever been a component of silver-free copper phosphorus brazing rods designated ASTM BCUP2? I know that BCUP2 currently means they don’t contain cadmium, so just wondering if older ones under BCUP2 might have contained cadmium.

Try a welders forum. This is about home inspections.

Couple of links for you.

Hope it helps a little.;_ylu=X3oDMTE1czAxNTE0BHNlYwNzcgRwb3MDMQRjb2xvA2FjMgR2dGlkA1ZJUDAyMl8xNDc-/SIG=11p8j4dpe/EXP=1319788919/**http%3A//
