Aluminum arrows were created in the 20th century by James Easton. They are known for their durability, yet they have a major drawback, they bend fairly easy, and this can be quite an issue. The biggest advantage of aluminum arrows is the fact that they are cheaper and, thus, better suited for beginners.
Carbon options are made using the latest technology. By comparison, models made of carbon are sturdier, less likely to bend and they allow for better penetration.
Moreover, options made of carbon are faster, while aluminum ones tend to be slower because they are thicker and bulkier. Furthermore, carbon arrows tend to get quite pricey, depending on the features that include. However, given their popularity among seasoned hunters, there are plenty of affordable carbon arrows that you can find online.
Another aspect that should not be neglected is the fact that carbon arrows may crack after extended use, while those made of aluminum do not.
