I saw this call for entries on the Yahoo metal clay group list. It was submitted by the Society for Midwest Metalsmiths, and the competition is called Metal Inclinations. For more details as well as an application (it cost $40 to enter up to 3 different pieces) see the society’s site:

The deadline for the METAL Inclinations International Exhibition has
been extended by popular demand.

Extended Deadline: July 28, 2008, Midnight PST
Applications are open to all metal artists living and working any
where in the world. Jewelry, hollow ware and metal sculpture are
accepted. Metal Clay artists are welcome.

Awards totaling $4,000

The METAL Inclinations online exhibition is a great way to get your
name and images of your work “out there” where the world can see it
and contact you. Each artist selected receives a gallery space with
their image/s and a individual artist web page/s with a link to their
own business or personal website or e-mail address. The exhibition
will run for one year October 31, 2008- October 31, 2009.

Sponsored by the Society for Midwest Metalsmiths a not for profit
organization dedicated to promoting, developing, educating, and
encouraging individuals who are interested in metalsmithing.
