I have a few skids of 6.50" OD x 48"-80.50" 6061-T6 aluminum cores. These came from our trepanning process. These should clean up well at 6.375". See the attached list of all Aluminum available. I can provide certs for the majority of the 6.50" material as 6061 T6. the balance of the cores I do not have certs for. Those grades of Aluminum could be 6061 or 7075. Most cores have a fin on the end. Some may have a fin in the middle, depending if we trepanned all from one end or from both ends. I have attached a picture. Payment via credit card. FOB Erie.
