Please log in for more thread options Can anyone please answer this, and/or point me to a website that gives some details ? What is that yellowish finishing that is usually given to a steel-based chassis for electronic products ? I assume that it is electroplated on for rust protection and solderability. Specifically, what is the plating material ? Tin ? | |||||||||||||||||||||||||

Plenty of old drawings called up 'Cad & Pass'. These days I use 'Zinc & clear'. Or actually more likely I use Zintec (tm) electro-galavanised material. Graham | |||||||||||||||||||||||||

I would suggest not welding it nor eating off it. Chris | |||||||||||||||||||||||||
