(这是一条买家关于"OFHC Copper Tube"的询盘信息，来自第108届中国广交会。)Inquiry Message (询盘信息) OFHC Copper Tube Hello, we are looking for 0.500"" ext. dia. annealed copper tube for pinch-off. The most commonly used metal for pinch-off is OFHC (Oxygen Free, High Conductivity) copper. ASTM B68-83, B75-84, B133-83 and B170-82 (CDA-101) give the specifications, chemistry and state of ductility for billet-certified 99.99% pinch-off grade copper. Because the material undergoes a deformation of approximately 350% during pinch-off, it is important that the materials be bright annealed at 650o C to 850o C for 30 minutes in Contact Info (联系信息) Vittorio Palmieri 1204 CHE Company: TVP Solar SA E-mail: palmieri@tvpsolar.com palmieri@tvpsolar.com
