what are its uses?
For making syrup, furniture and musical instruments.
Acer rubrum
 Thus, high grades of wood from the red maple can be substituted for hard maple, particularly when it comes to making stain/paint-grade furniture. Red maple lumber also contains a greater percentage of "curly" (aka "flame"/"fiddleback") figure, which is prized by musical instrument/custom furniture makers, as well as the veneer industry. As a soft maple, the wood tends to shrink more during the drying process than with the hard maples.

Acer rubrum [SEP] Other uses
One study compared the sap and syrup from the sugar maple with those of the red maple, as well as those of the "Acer saccharinum" (silver maple), "Acer negundo" (boxelder), and "Acer platanoides" (Norway maple), and all were found to be equal in sweetness, flavor, and quality. However, the buds of red maple and other soft maples emerge much earlier in the spring than the sugar maple, and after sprouting chemical makeup of the sap changes, imparting an undesirable flavor to the syrup. This being the case, red maple can only be tapped for syrup before the buds emerge, making the season very short.
