drawing platinum wire
 

Hi!

Can anyone explain, why the cost of production of platinum wire are so
high? 250 USD for 10m 0.127mm (AWG 36) diameter, 365 USD for 100m (value
of platunim metal not included). That is vastly more than e.g. the cost
of production of steel wire.

Are there any difficulties with drawing platinum wire, or is this just
because of small scale production. Platinum wire is made on a big scale
for use with catalytic gauzes, but probably small scale compared to steel.

Thanks, Bernhard
