Titanium Lugnuts. Please look. Thanks.

What alloy?

Have you considered 12 point pattern instead of 6 point to help with deformation over time? Plus, it's kinda theft prevention-ish.:rolleyes:

I have shopped these around my suppliers in China, made from Ti6Al-4V, no one wants to do them at the prices you are getting for less than 1000 parts! Good job if they are Ti6Al-4V. I would not trust Ti CP for this application, even though it cuts you cost in half...

TiAl????

Grades

The ASTM defines a number of alloy standards with a numbering scheme for easy reference.

* Grade 1-4 are unalloyed and considered commercially pure or "CP". Generally the tensile and yield strength goes up with grade number for these "pure" grades. The difference in their physical properties is primarily due to the quantity of interstitial elements. They are used for corrosion resistance applications where cost and ease of fabrication and welding are important.

* Grade 5 is the most commonly used alloy. It has a chemical composition of 6% Aluminium, 4% Vanadium, remainder titanium, and is commonly known as Ti6Al4V, Ti-6AL-4V or simply Ti 6-4. Grade 5 is used extensively in Aerospace, Medical, Marine, and Chemical Processing.[3]

* Grade 6 contains 5% Aluminium and 2.5% Tin. It is also know as Ti-5Al-2.5Sn. This alloy is used in airframes and jet engines due to its good weldability, stability and strength at elevated temperatures.

* Grade 7 contains 0.12 to 0.25% Palladium. This grade is similar to Grade 2. The small quantity of Palladium added gives it enhanced crevice corrosion resistance at low temperatures and high pH.

* Grade 7H contains 0.12 to 0.25% Palladium. This grade has enhanced corrosion resistance.

* Grade 9 contains 3.0% Aluminium and 2.5% Vanadium. This grade is a compromise between the ease of welding and manufacturing of the "pure" grades and the high strength of Grade 5. It is commonly used in aircraft tubing for hydraulics and in athletic equipment.

* Grade 11 contains 0.12 to 0.25% Palladium. This grade has enhanced corrosion resistance.

* Grade 12 contains 0.3% Molybdenum and 0.8% Nickel.

* Grades 13, 14, and 15 all contain 0.5% Nickel and 0.05% Ruthenium.

* Grade 16 contains 0.04 to 0.08% Palladium. This grade has enhanced corrosion resistance.

* Grade 16H contains 0.04 to 0.08% Palladium.

* Grade 17 contains 0.04 to 0.08% Palladium. This grade has enhanced corrosion resistance.

* Grade 18 contains 3% Aluminium, 2.5% Vanadium and 0.04 to 0.08% Palladium. This grade is identical to Grade 9 in terms of mechanical characteristics. The added Palladium gives it increased corrosion resistance.

* Grade 19 contains 3% Aluminium, 8% Vanadium, 6% Chromium, 4% Zirconium, and 4% Molybdenum.

* Grade 20 contains 3% Aluminium, 8% Vanadium, 6% Chromium, 4% Zirconium, 4% Molybdenum and 0.04% to 0.08% Palladium.

* Grade 21 contains 15% Molybdenum, 3% Aluminium, 2.7% Niobium, and 0.25% Silicon.

* Grade 23 contains 6% Aluminium, 4% Vanadium.

* Grade 24 contains 6% Aluminium, 4% Vanadium and 0.04% to 0.08% Palladium.

* Grade 25 contains 6% Aluminium, 4% Vanadium and 0.3% to 0.8% Nickel and 0.04% to 0.08% Palladium.

* Grades 26, 26H, and 27 all contain 0.08 to 0.14% Ruthenium.

* Grade 28 contains 3% Aluminium, 2.5% Vanadium and 0.08 to 0.14% Ruthenium.

* Grade 29 contains 6% Aluminium, 4% Vanadium and 0.08 to 0.14% Ruthenium.

* Grades 30 and 31 contain 0.3% Cobalt and 0.05% Palladium.

* Grade 32 contains 5% Aluminium, 1% Tin, 1% Zirconium, 1% Vanadium, and 0.8% Molybdenum.

* Grades 33 and 34 contain 0.4% Nickel, 0.015% Palladium, 0.025% Ruthenium, and 0.15% Chromium .

* Grade 35 contains 4.5% Aluminium, 2% Molybdenum, 1.6% Vanadium, 0.5% Iron, and 0.3% Silicon.

* Grade 36 contains 45% Niobium.

* Grade 37 contains 1.5% Aluminium.

* Grade 38 contains 4% Aluminium, 2.5% Vanadium, and 1.5% Iron. This grade was developed in the 1990s for use as an armor plating. The iron reduces the amount of Vanadium needed for corrosion resistance. Its mechanical properties are very similar to Grade 5. [4]
 
Yes TiAl...I was just typing short for Ti6Al4 Grade 5.

Thanks for the added information by the way. You know your titanium stuff...hence the name I suppose =)

Now the function of the rounded edges makes sense, not to mention they look much better than the straight edge IMO. I'm in for the rounded edges.
 
Alright guys. After taking people's advice, this is the lug nut I am modeling them after now. They will be the same shape as these, but instead, mine will be titanium and heat treated, and the top circular part will not have the little grooves on it. I will keep everyone updated on price etc.

Nice design, why heat treat? Is there an advantage for this application? I usually see 6Al/4V used in a CW condition for machined parts, only see heat treat when extreme temps are seen by the part. More often I see coatings to reduce friction and prevent gauling over time.

i have a concern about the heat treat issue as well. in reality you are not heat treating the part but heating it up on one end to produce visual discoloration which in fact reduces the strength of the material by destroying the original heat treat. furthermore, by affecting the material just on one side you are making the part inconsistent stress-wise. i am not a metallurgist but know enaugh about this stuff to think about it.

UPDATE!!!

Got the first sample units done and put them on a wheel to show you all. These are not yet burnt. I just got them to check fitment etc. Once things get closer to me releasing them, I will have close ups of the lugs, as well as exact prices and measurements (these units are much nicer, but b/c of the radius etc cost slightly more to make, but are well worth it IMO, and still hundreds less than the competition). When I do start selling these, if you want a set please get on it fast because I am only having 50 sets made, and once those are gone I will be done. Anyway, here is a quick picture for now. Exact sizes, prices, etc coming later.

Oh, and yes these are very light. The whole set of 20 lugs is around 1.3 lbs. Aluminum sets can be even less, but they are weak aluminum, and not titanium which is stronger than steel. I'll have exact weights as well once I have all other info for you.
 
Curious as to how many people will want a set of these. These will NOT work with OEM wheels :( OEM wheels need a more circular bottom on them.

I can make these with also the part on the bottom for OEM wheels, but I would need at least 10 confirmed people with OEM wheels for that.

The aftermarket wheel market is much larger, so I just stuck with that.

Anyways, if I could please get a head count of who all wants a set of these for stock wheels, as well as who all wants these for aftermarket wheels, that would be appreciated.

Price is set at $310 a set (includes shipping and paypal fees). I know it's now $60 more than before, but changing the design to a more complicated one raised the prices. :( It's still $200 cheaper than anyone else, and I feel mine look better.

OEM lug nuts (20 pieces) weight in at 1.4 lbs. or 22.5 ounces
So SS density is 8.0 and Ti density is 4.5 that makes Ti. lug nut is about 44% lighter.

Just an update on the lugs. They are still getting made. Been working on getting the heat treatment to look just like how I want. Then they will be getting tested and certified at a place in Dallas for hardness and tensile strength, then they will be for sale. These will be the best looking, cheapest, and most professional real titanium lug nuts on the market if everything continues as it has been. Please post here if you are interested in a set and I will not mind doing a group buy for them.
 
After months and months of hard work, I will be releasing these in just 1 more month finally!

-The shape is perfectly as I want
-The matte finish and heat treatment is perfectly as I want

Some things about these lug nuts that will separate them from the very little competition out there as far as REAL titanium lug nuts go.

-Certified (will show picture of certificate in ad) for 150,000 psi tensile strength as well as harness number of almost 800. Both of these before cryo treating which will increase these numbers.

-Look the best by far IMO and I'm sure you will all agree

-These will all be cryo treated

-These will be 7 sided, so they will be locking. I will obviously provide you with a very strong and well made socket to remove them as well.

Thanks for your patience everyone.

Now I know there are quite a few people that want a set of these for STOCK OEM wheels. Because of that, I will be making 10 sets with a different base that will actually work with OEM wheels. If I could though, I would like to get a list of the exact number of people that actually want these for OEM wheels. I will need that in case I need to make more. I'll make a separate the post shortly for people to reply to.
 
Collegeboy/Mike, since you're a new player in the vendor space, it might help if you can give more information* about yourself and/or get other Prime members or reputable members in other car forums.. (since nsx club might be limited in hawaii.. e.g s2ki.com I'm sure has them)

Maybe this has already been done, and I just missed it.. but the community would like to make sure you're not another Tamoske, no offense :)


*E.g.
-should be able to meet at least one reputable person that can vouch for you, at least one.
-business name and address (if you have one)
-shop contact info that you're working with and/or any other businesses that can vouch for you.
-provide your full name to the customer once you've established a relation with the person, and phone number to contact you. We don't expect you to print your full name on "the google," but since you're getting personal information from us, it's only fair to request the same in return.


..just my o..

After all of that, can't wait to see pics of the products and the list of offering! At the price you're talking about, you can give the main vendors a serious run for their money on some parts :)

Oh of course. Once I have my last sample in a week or so I'll post pictures of it along with a few pictures along the way. I just made the earlier post to let people know I'm still in the game. That's all.

Everyone will be very impressed.

Great!

As far as showing people I m legit, I have sold quite a few parts on this forum once I sold my NSX, but I would have no problem giving any customer my full name and address.

As far as one reputable person that can vouch for me...Vancehu. I have dealt with him at least twice I believe when I had an NSX. Also Ravi will gladly vouch for me.

I will not be giving out the shop that is producing my products though for obvious reasons sorry.

I am anything but a Tamoske.

Anyways, I look forward to the final product and showing you guys.
