Wutong wood is generally harder than elm. This is due to its higher Janka hardness rating, which is a measure of wood's resistance to indentation. Wutong wood typically has a Janka hardness of around 3,680 lbf (pounds-force), while elm wood ranges from 1,290 to 1,560 lbf. The higher the Janka hardness, the harder the wood is considered to be. Elm wood, while still durable, is softer and more prone to dents and scratches compared to Wutong wood. This makes Wutong wood a preferred choice for applications requiring a higher level of durability and resistance to wear.
