I have a metal container that is used to collect coins. Its lid is on a hinge and when this lid is hit it bounces, making progressively quieter noises each bounce. Fun stuff. Recorded with a boss br864 digital studio and a shure mic.
A simple recording of a metal drawer. Recorded with zoom h4n + sontronics stc-10 pencil condensors. This was recorded in my room so unfortunately the signal to ambient noise ratio isn't great, i think it's just passable though. The sound can be used for free (though it would be great to hear about what you do with it). It may not be re-distributed as it is, or as part of a compiled sound library.
Part of the turning cycle of an automatic screw machine making a small metal cylindrical part in a factory. Recorded with a rode nt4 microphone and the edirol r44 recorder.
Twanging a table knife on a desk, recorded with minidisc and condenser mic indoors, approx 6" distance. Background noise removed with audacity. Short metallic vibrating noises.
