Materials included are: Brass, Lead, Iron, Copper, Aluminum, Zinc0.8" (20mm) sides
Intended for use with Density, Specific Gravity, Specific Heat experiments
Where measurements are in both metric and imperial, the metric measurements are generally more accurate (the imperial are provided as a general reference).
These are designed to be used in an educational setting and are not fabricated using ultra high precision machining. Expect tolerances in the +/- 5% range of any stated dimensions (although they are generally much tighter).
