chromoly steel scooter deck

that is why i think a company should make a steel deck, only if there was a good enough idea, i think they should because there would be a lot less wear

Probably the same amount of wear- it would have to be thin walled tubing to match the same weight of an Aluminum deck so there wouldn't be much meat to the deck.

I'm fairly sure ulminium is stronger weight for weight than steel meaning that to have a chromo deck on similar size would mean that it would weigh a lot more.
On the other hand a really chunky carbonfibre deck seems legit, at 4 times the strength of steel weight for weight that could be cool except cost might be high.

They are SOME aluminum alloys that are Stronger than SOME steel.

You have it backwards- in a general statement using 6061 T6 aluminum vs. 4130, the Aluminum would have to be 3x as thick as the 4130 (Chromo) to equal in Strength.

We already have pretty thin walled Extrusion decks and to equal the weight of an Aluminum deck using 4130 the wall thickness would be way too thin, probably not even available.

If you use the same Thickness using steel, the deck is going to be heavier.

Bike Frames use Tubing that is Thin in the middle but thicker at the end so there is enough meat to weld or Braze the joints together.
 
I was thinking make a chromo version of the first TSI and use a wooden deckplate. The elasticity of the wood would absorb lots of the landing impact, steel would never grind away/through and weights not really that much of an issue unless your doing quint whips flat.

The one part that would wear the most would be the wooden deckplate - but those would be a cheap replaceable anyway.

i said stronger weight for weight meaning that 1kg of aluminium 6061 t6 would be stronger than 1kg of 4130 cromo if they were in the same structure but there would be more aluminium as it is less dense. im not sure if im right i think thats how it is though

1.Strength
The short answer to our original question is that in terms of strength, presuming an alloy and a steel vessel of the same design have been engineered correctly, they will have very nearly the same strength, with the balance tipped somewhat in favor of aluminum, both in terms of overall yield, and in terms of ultimate failure.
In terms of weight, the balance is tipped very significantly in favor of aluminum.
Of course, taking that one step further, if the aluminum vessel is designed to have exactly the same weight of structure as any given mild steel vessel, the aluminum boat will have considerably greater strength than the steel vessel.

Does all of this make steel 'inferior' to aluminum? Not at all..!

2.Flexness
The modulus of elasticity of aluminium (whatever grade) is only about 1/3 that of steel. So the deflection of an aluminium structure will be 3x that of a similar steel structure. If deflection is important you will need 3x more `second moment of area` (approx 3x more weight) of aluminium in order to achieve the same deflection as the steel structure. Aluminium is also 1/3 the weight of steel so both structures would now weigh the same.

3. S TO W Ratio
The reason airplanes are built out of aluminum instead of steel is because aluminum is generally 1/2 as strong, but 1/3 as heavy. So the strength-to-weight ratio is higher for aluminum.

i think all of that right

I have ridden a chromoly deck and it was extremly heavy. You think every company out there hasn't though about this and they obviously turned it down for a reason.
 
if these fucking scooter company's weren't cheap asses they would switch to 7075 and heat treat it, it has close to the same tinsel strength as chromoly, = stronger deck/lasts longer for grind whores.

I'm pretty sure Vertx OMG decks are7075 and heat treated.

There is no possible way they could be made from 7075 aluminum...just the block of 7075 needed to make one deck plate would cost at least several hundred dollars, if not a lot more.
I'm sure they are made from 6061-T6 at very best.... and the aluminum comes already heat treated. They are not welded, so there is no need for any additional heat treating (post weld heat treating).

7075 aluminum is a HUGE big step up from 6061. 7075 is amazing stuff...so strong...so expensive.
I would love to have a scooter deck made from 7075 it would be the sickest deck ever..and most expensive. lol
7075 is not weldable so it would have to be a 2 piece (bolt together) deck, but I would pay the extra price if a company would make one:cool:
Probably never happen.

really? i thought that 7075 was used in some bike frames which are welded and certain pegs for scooters, i am not expert but i thought that was the case .
