Die opening with a relieved profile.

Bending aluminum channel.

You d probably air bend by using a 3 0 in. You can find your bend allowance with the following formula. We have the ability to bend channel the easy way against the weak axis and the hard way against the strong axis. Aluminum channels are an excellent choice for applications that require strength and corrosion resistance.

Bending aluminum channel into a helix is even more of a challenge. You have now annealed your 6061 t whatever into t 0 and it should bend without cracking. Step 1 use just act. See a list of the most common aluminum channel sizes available at eagle today.

Say you re bending 0 25 in thick 6061 t6 aluminum to a 100 degree external angle 80 degree internal angle. Their severely asymmetric shape undergoes a large twisting force during bending and the legs try to move toward the central axis. I ve bent a fair amount of 6061 aluminum the trick i was taught was to heat it with oxy act torch. Eagle s aluminum channel stock is available in a variety of different sizes lengths and wall thickness.

π 180 x b x ir k x mt bend allowance ba where b is the angle complementary to your desired bend angle 1 to 180 degrees mt is the thickness of the material ir is the inside radius and k is the k factor. Step 3 heat part until black soot goes away. We can bend all types of channel including aluminum stainless and carbon steel. With the right tooling machine machine operator and process however some impressive bends can be read more.

Hand fabrication using heat. We can bend channels with the flanges out with the flanges in and the hard way of the web. Bending aluminum channel can be difficult. Channel sections asymmetry is the enemy of easy bending which is why channel sections can be so difficult to form see figure 5.

Common aluminum channel sizes. Standard channel and miscellaneous channel are specified in similar fashions. And coat the area to be bent with soot step 2 turn on o2 and set rose bud to a normal flame. Chicago metal is the leading resource for steel and aluminum channel bending and more.

An example callout for standard channel would be c12x20 7. Under extreme conditions it tends to crack.
