Inquiry (采购产品): Thermal spray copper I need to acquire 20 pounds of 99% pure copper powder for a sample thermal spray coating. The powder should be sized between 20 and 70 um and should be processed/packaged to minimize oxidation. Ideally, the powder would be shipped under an inert atmosphere. Please provide price and delivery. **** Hidden Message ***** David Jewell 23129 USA Company: Solid Spray Technologies E-mail: sales@solidspray.com **** Hidden Message ***** sales@solidspray.com
