GB,
They use titanium bolts for holding on 747 engines.
I'd say they are stronger than steel, do NOT rust and are as light as fukc.

Apparently "special" titanium to be used to replace high tensile steel applications?

My old man used to be an aircraft handler at Heathrow.
The 2 meter bars from the tug to a Jumbo front wheel was made of titanium as no other metal could handle the streatching forces.

The lack of weight for manual handling too I'd say.

I thought I saw something on the Probolt website that titanium is not suitable for certain applications and tensile strength is affected but I'm using my phone so can't bloody find it now. It might be something to do with heat.

Appears to be quite a few different grades / strengths of titanium.

tensile strength steel= 800Mpascals (M=Mega)
tensile strength 6AL-4V=900Mpascals
yield strength steel= 640Mpascals
yield strength 6AL-4V= 830Mpascals
Titanium will always be stronger, especially tensile (stretch test) compared to steel, however titanium is more susceptical to shock compared to steel. Because the bolt you are using is not under violent shocks it is safe to say that the titanium you have chosen is safe to use......this pm will not stand up in a court of law though
Aerospace grade 6AL-4V and any other aerospace graded titanium is no better than normal 6AL-4V. The difference between them is traceable paperwork with respect to the tests that are conducted on manufacturing each batch of said grade titanium. In short, all aerospace grade titanium is fully traceable from it's supplier through to its testing. Normal non aero grade does not have to be so traceable. If an aircraft drops out of the sky....they want to know why and therefore everything must be traceable. If a car crashes... no one gives a fuck.
So, if anyone offers you aero grade titanium remember that it is no better than normal titanium of the same grade ( it is no stronger than normal non aero grade) but will be more expensive due to the traceable tests that are conducted on each batch......you are helping to recover their costs of testing buy paying more.

I used to use a lot of titanium when in the plating industry and to be honest apart from being light it is not all that great, quick wearing, cracking, and erosion were problems I encountered went back to using stainless parts where ever possible, for suspension linkages I would go for the proper high tensile bolts.
