What is QQ-N-290 Grade G





Can anyone tell me what FED-QQN-290 (replaced by AMSQQN290 [affil link]) , Class 1, Grade G represents. I cannot get through on the ASSIST web site. Need immediately. Many thanks!

QQ-N-290, Class 1, Grade G represents a 0.0002 inch (5 micron) nickel plating. It can be used for copper and copper-rich alloys (< 40% zinc).

QQ-N-290 is in fact still available from the ASSIST site, as are many other canceled specifications [just click on the document icon]. Download any of foreseeable use, since future availability is uncertain.
