I'm gonna be totally honest I have no idea what that means, are you casting your own stainless with another metal added ? Is that it ? Don't mean to look stupid but I gotta ask. I love learning Different things about this. Is there a video I can watch maybe explaining it?The base metal is 416 stainless.
As a tip: I fill them with cerometal, for the engraving process, for both reinforcement as well as noise reduction. One word of caution, cerometal will bond to gold and silver so be aware when melting it out.
