In the United States, oak wood is generally more expensive than ash wood. This discrepancy in pricing can be attributed to several factors, including the demand for oak, its durability, and the specific species of oak being used.

Oak, particularly red oak and white oak, is highly sought after in the woodworking industry due to its strength, durability, and aesthetic appeal. These qualities make oak a popular choice for furniture, flooring, and construction projects. The demand for oak wood has driven up its price, as suppliers must often source from limited areas where oak trees grow, such as the Eastern United States and Europe. Additionally, the process of harvesting and processing oak wood can be more labor-intensive, further contributing to its higher cost.

Ash wood, while also durable and versatile, is less expensive due to several reasons. First, ash trees are more abundant and can be found in various regions across the United States. This higher availability makes ash wood more accessible and less expensive to source. Second, ash is often used in applications where the aesthetic qualities of oak are not as critical, such as utility furniture or less visible structural components. Lastly, the demand for ash wood is not as high as that for oak, which keeps its price relatively lower.

According to the U.S. Forest Service, the average price for oak lumber in 2020 was approximately $3.50 per board foot, while ash lumber was priced at around $2.50 per board foot. This data highlights the general trend of oak being more expensive than ash. However, it is important to note that prices can vary significantly based on the specific grade, thickness, and width of the lumber, as well as the market conditions at the time of purchase.
