Tie rod aluminum quality/grade?

What quality/grade of aluminum do you believe the tie rods are constructed, or if you were to recommend an aluminum grade?

David,

Thanks. I have a set of lowering links.

I am going to make up a set, specific to my height, and don't know the type of aluminum (grade) bar to purchase.

So that's the interest of my question, what is the appropriate strength aluminum grade?

Looking for someone who knows aluminum. I do not want to 'under rate', or misapply any aluminum ideas I have.

I would use 7075

Typical Mechanical Properties**:

Tensile Strength (PSI) 83,000
Yield Point (PSI) 73,000
Elongation 11
Brinell Hardness 150

Note that ordinary structural steel has a Yield Point of 44,000 psi, so that gives you an idea of the strength of this alu.

In addition, aluminum has no fatigue limit. So be sure to radius all diameter transitons to minimize any stress risers.

Pud 1, thank you for the info. By radius I understand that to mean any changes in width points are 'curved, so basically make the tie rod look like the OEM, as example?

Thats right. NO hard 90 degree corners. Fillet radius them out. The bigger the fillet radius the better. If you want, you could send me a picture of your plan, and I could review it. I am a P.Eng - Mechanical. This sort of thing is right up my alley.

Pud1,

What a nice offer. I will do it. Thank you.

I intend on just copying the OEM link, and lengthening it about .7 mm, however, I might do up a multi lowering end. Have not decided yet. I hope to have the material ordered by next week.
