Inquiry (采购产品): Type III anodize w/ PTFE vs. EN w/ PTFE Greetings, I was wondering if it is cheaper to do a type III anodize w/ PTFE applied or a PTFE impregnated Electroless Nickel coating, either on a small 5052 Aluminum part. Also do you charge by the batch or by the part? Thank you, Kurt Sonnenberg **** Hidden Message ***** Kurt Sonnenberg 100 N.
