Didn't know that....Interesting.....I know of a few mods that use steel connectors (contact points)

They stay cleaner but thats not the point on e-cigs Tim. And I am sure that you dont want that too. I can easily make steel connectors and GGs but I dont think so. Heavy pieces with no good contactivity? No for sure:)

somewhere out there......
best conductive metals

Silver: best

Copper: 9% less conductive than silver

Aluminium is 10% less conductive than copper

Gold: 24% less conductive than copper (but doesn't tarnish or corrode)

Brass is somewhere here.

Rhodium: 74% less conductive than copper

Iridium: 77% less conductive than copper

Platinum: 84% less conductive than copper

Stainless steel is somewhere here.

Titanium: Over 99% less conductive than copper

so pure copper would be the best choice as far conductivity... aluminum is better than brass... but silver is by far the best conductor but very expensive for GG's use.
The best combination for weight and contactivity is by far the aluminium. Nice index Grimmer!

ps...... copper is heavy and it cant machined, its like a chewing gum for the machines

lol that is what I read to about manufacturing copper.... pure copper is tough but maybe you can make the thin contact points in copper and the rest stays in brass.... like the thin center post could be copper and the spring as well... just an idea :)

The total resistance of an cig will be the same as the metal with the bigger resistance. Imagine an all silver GG with only one touch of steel. The total resistanse will be the resistance that steel has

that makes since, considering the flow of current is used by the entire GG.... I guess a solid aluminum GG and all parts would be the best bet then.... :) In other words the button, the body, the spring and all contact points needs to be aluminum.... ooooooooooh I want one. even if it boost the performance of the attie by 5% its still a 5% boost. :) A 5% increase in air intake in an engine can help boost performance in most basic cars and help increase gas milage.

I agree to that Grimmer. And it would be very light too. The performance of GG is already bigger than anything else and I wanted to make an all aluminium GG but factory had already made the bronze parts.

ps....... Even if a metal had the same contactivity as the aluminium, I would prefer the aluminium because its 3 times lighter. 3 times lighter!!!!! People that dont have smoke the GG cant understand the difference in weight. Who wants to smoke 3 GG together? They are really heavy!

I'll tell you what.... once you get all aluminum parts going into your GG's you will have a really great performing ecig and not only that it will be the lightest to (and the GG already performs great now but a 5% increase would be sweet)....

lol I would not want an all copper mod.... no way that thing would be to heavy lol... so really an all aluminum GG would be the best.... I say get rid of the brass pieces unless you still want to sell the brass buttons... but honestly if the performance will increase and the atties function better than go all out with aluminum... or do both styles.... besides an all aluminum GG would bring the price down a smidge.... because you wouldn't have to buy two different metals. The more you order one type of metal should help with your costs.

The cost isnt a big deal because the brass parts are very small Grimmer. But aluminium is difficult to be machined in small parts. Its not impossible but it is just more difficult.

The Super 6 which is stainless steel weighs only 2.5 oz with 6 volts and the GG weighs 4.3 oz with 6 volts.

Why is it that SS is lighter than aluminum.

The GG does produce better at 6 volts than the Super 6 at 6 volts. This must be because of the aluminum.

the super 6 is not stainless it is aluminum, I know I have one. Unless David changed it up but from what I can tell its still aluminum. Either way the GG and Super - T are in a league of there own and there both extremely well built mods there is no need to compare.

The GGTS not only performs better, but it IS not to be compared with anything: period!!!! ;);););)

The following is from somebody who knows what he is talking about!

As for the thermal conductivity, aluminium is far better than steel as heat is coming out very easy, so the heat don't stay on the battery, so its life is extended.

As for the electrical conductivity. Its well known that steel is one of the worst metals to electrical conductivity. The corrosion of aluminium is because it is a much more "active" metal to electricity then steel so therefore it needs cleaning. Also we never use steel where good electrical conductivity is required because we loose large amounts of energy. There is not one wire in the world made from stainless steel. We need at least 3 mm wire of stainless steel to reach the connectivity compared to 1mm aluminium wire. Also electrons runs much better on the aluminium that on steel. And if you search though internet you will see that everybody says that steel is a bad conductor of electricity and nobody uses it for that purpose.

The total resistance of a mod is the resistance of its weakest point. So if a mod is made all from silver and only one piece is made from another material then the total resistance of the mod is the resistance of the other material.

You can see in this video too how steel affects the connections:

Electrical Resistance of Stainless Steel - LiveVideo.com

Besides all the above: aluminium is 3 times lighter and of course can be polished way more easily than steel.

So it is clear: Steel has no advantages at all :D:D:D

so...I have my BSB and my FogLog...both usually run an 18650 battery..so I should expect the GGTS to be lighter or about the same weight?

BSB is thick but GGTS has the brass telescope and the brass cap so maybe they are equal, I dont really know. Other factors like the internal parts may affect the weight wolf:)
