岩榆樹種的木材，堅硬，細枝上通常生有軟木脊。是所有榆木中最為堅硬、沉重的一種，樹幹上少有樹節，堅固，可高度打磨拋光。在北美洲與歐洲應用於製作船隻、家具、農具與樂器。由於生長緩慢，形成的木紋十分緊密，因而讓木頭相當堅固。

岩榆(種)

英文....

Wood of the species Ulmus thomasii, having hard wood and twigs that often develop corky ridges. The wood is the hardest and heaviest of all elms, relatively knot-free, is strong and takes a high polish. It has been used in North America and Europe for shipbuilding, furniture, agricultural tools, and musical instruments. Much of the timber's strength is derived from the tight grain arising from the tree's very slow rate of growth.
