Magnesium Riser
I have been wondering why no bow companys do not have risers made out of mag? Magnesium is lighter,way stronger and cheaper
to produce then aluminium.The military has some of there stuff made out of mag that once was made out of aluminium,they switched mainly because of the strenght and lighter weight. Stronger riser and lighter bow sounds good to me, might even bring the price down on them. |
RE: Magnesium Riser
i thought my Reflex Highlander had a magnesium riser.......? could be wrong...pretty sure its different from most bows...

RE: Magnesium Riser
I'm not too sure Magnesium is cheaper than aluminum.

RE: Magnesium Riser
Magneisum archery risers are made in molds and bottom line, they are not as strong. or precise as a forged/machined alum riser. They get tiny air pockets among other things which obviously reduces strength. Hoyt is about the only big company using cast magnesium anymore, and I've seen a couple goofy reflex Growlers and new "Hawk" series bows-you can get bad "runs" of cast magnesium risers- even from the best manufacturers and thats the way it's always been. Hoyt simply cannot make a "tec" riser out of machined aluminum in the price range that they need. Costs too much-hence the rleiance on cast magnesium technology.
Darton tried using machined magnesium risers back in the mid 1990s- they were a flop- they did not prove to be any better than a machined aluminum riser ,looked "cheap" (much like PSE's "forged" F series risers) , and required far more expense to manufacture properly because magnesium is much more volatile/flammable- they often snapped because the heat was not properly controlled thus weakening the molecular structure. |

RE: Magnesium Riser
lol OH, i actually have thought of that.....im familiar with the magnesium fire starters...i usually got 1 somewhere if i got my pack with me...
if i had to do it, it would be done no doubt about it! |
RE: Magnesium Riser
If its anything like fishing reels, they transmit vibration much better as well.

I've seen Mag risers break! Not Good!! Dan |
RE: Magnesium Riser
Is there a reason why you couldn't forge and machine magnesium like you can aluminum?

RE: Magnesium Riser
Magnesium riser are cast out of a mold,or more correctly,a die.AND yes,they are not as strong as billet aluminum risers.I have seen them break in 2 at the grip.Glad I wasn't hanging on t it.;)
BUT,let me add that the technology today is leaps and bound above what it was just a few years ago.The newer hoyt magnesium riser are practically bullet proof. Aluminum risers are cut out of extrusions,not forged.I would personally like to see a forged, aluminum riser.That would be the most stable and strongest riser one could get. I believe forging will be the next technological advancement in riser design.Might even be a dropped forged riser. Arthur,where you at? I know you have some valuable input on this subject. |
RE: Magnesium Riser
BowTech's risers are forged and then machined.

RE: Magnesium Riser
BUT,they are not forged,they are cut from forged billets.
To my knowledge,most still use 6061 extrusions. |
RE: Magnesium Riser
I was not aware that these companies were using forged billets.Might be a step in the right direction.

RE: Magnesium Riser
I had a Hoyt Ultra-Mag at one time and it was mag. I never had an issue with it and it seemed durable as can be. I have never heard of any of the newer Hoyts made from Mag breaking but i have heard people talk of older bows breaking in the riser.
I believe the PowerHawk, and the SuperHawk are still made from magnesium. The SuperHawk has laminated limbs as well. Derek |
RE: Magnesium Riser
The problem with the casts/molds is stuill one of air pockets and other imperfections. Start taking a good look at the Reflex Growlers/powerhawks/superhawks at full draw- you will see the occasional one that flexes (for lack of a better term- bend) at full draw. Jimmy Despart started to notice this (he runs Flying Arrow Sports II near Albany)- and now my my local shop (original FAS) is keeping an eye on all of them when they come in.
This is nothing new however- my first Magnatec (Powerflex w/ C cams) had this issue. At full draw you could see the limb pockets lean to the left as cable tension was reduced at full draw. |
