Your husband may be interested to know I currently have a customer who makes a very hi-tech piece of hardware for a US aerospace company that is machined from aluminium 50 % Silicon we developed this for the very low thermal expansion properties it?exhibits at?very low temperatures. Sorry I cannot tell you the application its used in but the piece of hardware helps to prevent the loss of airmans lives, both yours and ours. Kind regards Phil. P.S. I was chatting to some guys from Reynolds Aluminum at the recent Paris Air Show ( Also got some great Paris street pictures a la Henri Cartier Bresson ! ) ________________________________ From: Tina Manley <images at comporium.net> To: Leica Users Group <lug at leica-users.org> Sent: Wednesday, August 19, 2009 12:58:16 PM Subject: Re: [Leica] BOATING PAD - COMET At 05:03 AM 8/19/2009, you wrote: > Ric / Jim, I work in the aluminium industry, and for many years I worked > for Alcan, which is how I got to spend three years in Riverside CA., and > where our daughter was born, she kept her US passport !

My husband worked for the aluminum industry for many years - Reynolds, Alumax, Iralco, Venalum - and started his own engineering consulting firm Penta that worked with Alcan and most other aluminum companies.? His area was mostly recycling aluminum but we've visited aluminum plants all over the world.? Maybe our paths have crossed over the years!
