Hi Everyone,
 
Am enclosing details of Cu isotopes/powder available from a very close colleague in the UK, he is the owner of the product, I believe they offer the best prices in the market.
 
Cu63/65 up to 500Kgs is $3,000 per Kg  anything over is 500Kgs is $2,500 per Kg
 
The applications of Ultra dispersed Cu isotope powder are in following industries.
           1. Aviation finer parts manufacturing.
           2. Metal Refining
           3. Micro Electronics
           4. Medical equipment
           5. Defense sensitive parts making
           6. Engineering (Sintering)
           7. Oil refining processes
 
Here are the details of the Cu as well as photo attached.
