<p>The present invention relates to improvied materials for fabricating can bodies. In particular, the present invention relates to can tooling components (20) fabricated from whisker-reinforced silicon nitride having from about 5 to about 15 weight percent whiskers with an average diameter of at least about 0.75 micrometers. The material preferably has a thermal expansion coefficient of from about 0.20 to about 0.24. The present invention also provides a method for reducing the trim height of can bodies (30) formed using a can tooling apparatus (20, 40, 50, 60, 70, 80).</p> |
