The metal is very reactive and oxidizes in air. But, AFAIK, the oxide forms a very thin layer on the surface, as is the case for aluminium, so the amount of oxide produced from CuBe250 (the 'cooking' grade of beryllium copper, AIUI, with 2.5% Be) is very small indeed in normal use. Machining it is a different matter. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk After swimming across the Hellespont, I felt like a Hero.
