In an increasingly competitive market it is necessary that the forestry companies conducting permanent search for genetic materials that provide wood with appropriate properties for a particular purpose, combined with high productivity in the shortest possible time. In this context, this research fits, since it is proposed to verify the wood properties of different genetic materials for the charcoal production, at different ages. This study evaluated three eucalyptus clones, being a Eucalyptus grandis x Eucalyptus urophylla hybrid and Eucalyptus urophylla clones at two, three, four, five and seven years old, with a 3.5 x 2.5 m spacing. The clones are from Gerdau S/A. There was effect of the age on wood properties, the three evaluated clones, providing gains in charcoal quality and increased energy production per m3, but there was no influence on the yield gravimetric charcoal. Evaluating only the wood propertie for the best genetic material selection, the GG 680 clone had the highest potential for the charcoal production. It should be noted that the three clones meet the specifications for use steel making, with satisfactory gravimetric yield.
