James Easton invented the aluminum arrow in 1939. Aluminum arrows have significant advantages, but also disadvantages.
The advantages
Costs, exact weight specifications, can (if possible) be straightened again
The disadvantages
Do not fly as flat as other arrows, bend, "accessories" are somewhat rare, lighter arrows can also be somewhat thinner
With which bow
Aluminum arrows are primarily preferred by recurve, barebow, and compound archers. Experienced tournament archers, in particular, appreciate the advantages of aluminum arrows.
Not for beginners
Aluminum arrows naturally bend much more easily. Therefore, they're not necessarily suitable for beginners. Missing the target can cause damage. This also applies to incorrect pulling.
In the hall
Aluminum arrows are popular for indoor shooting. Especially at relatively short distances, such as 18 to 25 meters, they guarantee stable, repeatable flight. Experienced tournament archers and skilled compound archers love these arrows.
Conclusion
Aluminum arrows are a durable alternative to wooden arrows. Only inspect/touch good quality material at a retailer and, of course, try it out.
