Can anyone please tell me what the allowable percentage of copper in aluminum is to be considered "copper-free". The American Petroleum Institute specification API 541 (3rd ed) uses a limit of 0.2% copper, but I have seen a limit of 0.4% used as well. Is there a standard limit that I can use or is there no universally accepted definition for "Copper-free"?
