Titanium Nails- Imported from China

[Tudo]

Read an ebay listing that stated that we should buy from them because they sell only top quality titanium made in the usa while the seller went on to state that many of the "other" ebay sellers only claim there titanium nails are titanium and in fact they are selling cheap chinese knock offs that give off toxic gas etc when used.

The seller has some kind of certification ......in russian.

Question, how can you tell the difference between the so called cheap chinese knockoff and the made in the us version. #2 is it true about the emissions from the alleged cheap chinese knockoffs? 3) How do you know it's true? How do you know it's not made in china and just sporting the made in us trademark?

You know by buying nails from reputable american made manufactures, like highly educated and dab n flow.

Don't buy your nail off ebay, check out aqualabs for HE products, the new HE infiniti nail it works on every joint male or female 14mm or 18mm, it's adjustable and domeless. Pretty sick

iuno.

I have actually bought one of those eBay nails.

The toppers were titanium, came with a cup and nail style, but the shaft was definitely not.

Big waste of money as I can't trust the quality of the ti in the heads cause they lied about the shaft. Heh they work though, as a buddy used it by mistake for like a week when he was house-sitting and preferred it to the quartz nail setup I left out.

Second the recommendation for HE products. I use a few of their nails including the e-nail and its all amazing. And the owner Task is really out there pushing the whole scene forward.

Task is a g for sure! I don't know of any other company providing the amount of variety he does, got everything for your titanium needs and more.

So there's no way to tell the difference?

Okay, I'll bite - are you talking about actual nails?

Bite what? It's a simple question. How do you tell the difference?

Okay, I'll bite - are you talking about actual nails?

no, they are not. but close. these are almost nail shaped things with a space on top to vaporize oil on.

A Kevex or gas chromatograph is normally used. You can't tell by looking.

The cheapest Ti on the market is 6AL4V, which has aluminum and vanadium as alloying agents. The Soviet Union dumped a ton on the market when they scrapped some of their subs.

What we want is Commercially Pure Titanium, without alloying agents.

Downed this for a microlight project , supplier should be able to say which ASTM grade it is , 1 to 4 are pure but not always the cheapest , not all are readily available in billet , bar and tube.

Can tell the pure ones apart by an impact test or a centre pop untill heat treatment , but they are the same apart from machineability for this purpose.

Grade II is the popular CP grade for nails and skillets.

PS: 5AL2.5V is the second most common alloy scrap available.

I was reading something that states, if you hold a dremel tool and grinding stone to the Ti in question, there should be a spray of Bright White sparks, as the Ti burns so much hotter than other metals it becomes incredibly bright.

ANy presence of other metals would leave a orange yellow trail indicating otherwise. I wonder if this would help indicate whether the Metal/Nail in question is what we are looking for, or if this would be a vague indicator.

This article states that all the unalloyed Ti is CP and suitable for our purposes, the difference being overall durability, strength and degradation.

Maybe these cheaper Titan owl products (likely Grade 1 Ti) are ok after all. DabTech site openly states they use Gr1 Ti and that it is safe to use.. Not sure who they are though.. I bought one without doing my homework and now will be running this test just to see what I get.

The sparks from unalloyed titanium are certainly white and very bright , have nothing alloyed to compare against.
If its alloyed with palladium , vanadium or ruthenium I would not be too concerned as the burn off temps are so high , but would avoid aluminium and tin (Sn).

Its proving very hard to machine and thread , tends to work harden and pick up on the tooling , will be using aluminium alloys for most of the airframe thanks to this and the crazy cost.

Vague indicator is a good description for spark testing.

We Kevex tested a cheap import and it tested CP Ti with Zirconium used joining it to the shaft.
