Most Common Materials of Arrow: Modern arrows are tubular and made of carbon (carbon fiber), aluminum, or a combination.
Combination of Carbon and Aluminum:
It consists of a thin aluminum tube covered by two layers of carbon. The two dissimilar materials acquire relevance with special processing. Precisely due to their non-uniformity, very high rigidity is created. They are the thinnest and lightest arrows, so they are the most popular for championship archery.
The Most Common Are Easton a / C / E and X10:
The hardness code of A / C / E and X10 is a number that indicates the bending arrow in millimeters of an inch, which occurs if the arrow is placed on two-point supports 29 ” apart and a force of 2 lbs is applied in the middle. e.g., hardness 920 indicates that the arrow will bend by 920/1000 ” (23.37mm).
100% Carbon (Carbon Fiber):
Good quality recurve bow carbon arrows usually have four carbon fiber layers in an intersecting direction. This gives considerable rigidity and strength to the arrow. They are thicker and heavier than carbon/aluminum and very resistant to mechanical stress. They are used in field archery and hunting but also in archery, mainly in indoor competitions. The best known are the Easton Redline. The codes are specified as in A / C / E.
There are also the most economical ones that consist of only one layer of carbon with reduced durability. They are mostly used for education and leisure.

They are the most common because they are economical, durable and in extreme mechanical stress, do not break but simply bend. In most cases, they can be repaired, unlike the carbon that is destroyed. The best quality is made from aviation-type aluminum alloys such as 7178 (Easton X7) or 7075 (Easton XX75). They are usually heavier than carbon. They are used for indoor racing, training, field, and hunting.
Their code is a four-digit number; the first two digits denote the diameter of the pipe at 64a of the inch, the other two the thickness of the wall of the pipe in millimeters of the inch, e.g., in 1814 indicates diameter 18/64 ” (7.14mm) and wall thickness 14/1000 ” (0.356mm).
The wooden ones Arrows are now used only in traditional archery.
There are also solid fiberglass arrows, but they are very heavy and are only used for recreational archery in hotels or clubs.
The plumage gives the arrow the necessary stability for the flight. It consists of 3 plastic wings mounted at 120 ° angles. The wings have been shown solely to give a sense of proportion. The wings have been shown solely to give a sense of proportion. Straight ones are the most common due to their exceptional durability. Spins are typically used with Easton ACE strains in outdoor archery.
The size of the wings is determined by the arrow’s weight and the style of battle. The heavy arrow needs a bigger wing, and also the bigger the wing, the faster the arrow straightens. Thus, in the heavier arrows (such as those for the compound bow) and those for indoor races, larger 2.6 ” to 5 ” wings are used. But because the large wing worsens the aerodynamic behavior of the arrow, in outdoor races where the distances are long and the crosswind is significantly affected, the smaller wings, 1.6 ” to 2.3 ” are usually used.
The natural feather has almost been removed from the races because it is much more sensitive, expensive, and affected by moisture. But he still has fans in hunting, field archery, and traditional archery tournaments.
The Plastic knock:
It adapts to the carbon arrows wedges while to the aluminum ones with glue.
The nose is metallic and consists of the visible and the invisible part. The invisible has exactly the diameter of the inside of the tube and is fitted to it with hot-melt glue. This glue is in solid form and liquefies with heat. After cooling, it retains some elasticity that makes it absorb the shocks of impact without crumbling. The nozzles are available, for each inner diameter of the pipe, in different weights. They usually weigh from 50 grains to 150 grains. The weight is selected by testing so that the arrow flies correctly. When we want to “soften” an arrow, we put a heavier nose and the opposite when we want to “harden” it.
For hunting, there are special hunting heads (broadheads). They have radially mounted 2, 3, or 4 steel blades that can be replaced.
The blades are fixed or open instantly as soon as the arrow hits the target. The cutting diameter is up to 1 ” for the fixed ones and up to 3 ” for the opening ones. For large prey, there are the heaviest and most reinforced titanium heads with a special design to break a bone (bone crushers).
They are screwed to a special insert that is stuck inside the arrow stem. They weigh from 75 grains to 150 grains.
The weight of the arrows and their accessories is measured in grains (= 0.0648gr)
