Most companies buy those lids with the braze already on them. I remember running 1000# of brand new, unused lids, about 1/2" square, with braze on them, that ran 1 oz Au per pound, or 68g/kg. When the lids are removed from an assembled package, about half will be on the lid and half on the seal ring of the package. That makes the 30g/kg figure quite reasonable.

Thank you very much good sir. :mrgreen:
Yields will vary also depending on how you remove the lids.If you are a lid buyer this should be a deciding factor on what to offer or pay for them.Thanks in advance.
P.S I hope everyone has learned a little something new from this thread.
P.S.S Just remember you can learn a lot from a dummy like me.

Certainly. I always removed them on a heated rail set a little over the melting point of the particular braze. With that, it's about a 50/50 split.
