Aluminium engine hangers.

(1/2) > >>

Some while ago I acquired in  box of bits, some aluminium engine hangers  the triangular ones at front of engine, that connect to front down pipe. While I'm waiting for rebore was having a sort out and thought bet they'd polish nice, and they have. But never seen them before,   they are exact copies of the originals.
In my head aluminium is a strong lightweight metal , would they cope with weight/ stresses etc while in use.
I know not standard but I do like a bit of being.

My first thought is there are different grades of alluminium with varying metallurgic specifications.
The original steel ones are pretty thin so I suspect they are more of a steadying mount against vibration & torque movement.
I would expect alloy ones to be substantially thicker - they might have a high Titanium content to compempsate - do you know who made them?

billdn:
No idea Ted, and they are only as thick as the original metal, which I still have BTW.

McCabe-Thiele (Ted):
Are you sure they are not Steel/Titanium defo Alluminium?

I bought a job lot of 400 bits a couple of months ago and there were some ali front engine brackets, so cant be that uncommon
