Inquiry (采购产品): 5 aluminum tube/rod I am working on a research project to build a sample collector for anspace mission. Our collector needs an outer ring that will be 5" in diameter and has a wall thickness of 1/2" on one end for a retainer ring. We will only need 30" length to build collectors to test at the end of February. Do you have material we can machine to these specs? **** Hidden Message ***** Walter Graupner University of Arkansas Fayetteville, AR 72701 USA Company: Center for Space and Planetary Sc Title: Lab Manager Phone: 479-575-3170 E-mail: wgraupn@uark.edu **** Hidden Message ***** wgraupn@uark.edu
