Stainless or Aluminium Scoop?

I just got this ss scoop from a guy on ebay only 99.00 shipping is free its just the scoop, the handle is a post hole digger handle ,available at most hardware stores for about 10.00
It's the design... how they are made.
If you made two scoop heads the same... one made from 304 stainless and one from Grade 5 titanium...
the titanium scoop head would be 45% lighter in weight... and about 45% stronger.
If you wanted both scoops to be about the same strength... you could make the titanium head using thinner material and the titanium head would weigh about half as much as the stainless head and be just as strong.
Grade 5 titanium is about three time as strong as aluminum, but only 60% heavier.
Making a scoop using aluminum to match Grade 5 titanium's strength wouldn't even be considered!
You ever wonder what metal is used on an aircraft's "Black Box"?
It's made from a metal that has the best strength to weight ratio of any...
It's corrosion resistance is second to none... even stainless...
It keeps its strength at high temperatures better than all metals compared to it strength and light weight...
It needed to be the "survival piece" to tell the story under the most severe crash...
Might be a great metal to use for a sand scoop!?
Oh..Well...
If my scoops are ever in a plane crash, the scoops maybe the only piece left...
... and the "Black Box"!!

Number9.the properties of titanium to tell me do not ... 
I have 2 higher education.
I constantly have to deal with titanium.
the way the American plane sr-71 is made of titanium Ukrainian ..., well, the problem you had at first because he did not know how to cook and work with him ...
and we have of him not only aircraft but also makes submarines, and even shovels ...
but I agree with you-wonderful titanium metal, but it is desirable to apply the scoop Grade 1or Grade 2
I asked about something else, why your stingy titanium weighs more than my miserly stainless steel? stingy with my size more ...
no sense to do that either titanium if it weighs more than the stainless steel ... imho.

The ONLY advantage for using stainless for a sand scoop and not grade 5 titanium, is the price of the metal.
Grade 1 and Grade 2 titanium is pure titanium ( first four grades of titanium is considered pure titanium).
Grade 5 titanium is 4 times stronger (tensile strength) than Grade 1 titanium...
Grade 5 titanium is 2 3/4 times stronger (tensile strength) than Grade 2 titanium...
The SR-71 Black Bird first flight... Dec. 22, 1964.
The top speed was in excess of 2,193 miles per hour (above Mach 3) at an altitude of over 85,000 feet. That breaks down to about 35 miles per minute.
Blackbirds are constructed with a titanium alloy that makes up about 93% of the plane's empty weight.
At the time it had no equal and still holds many records in speed and altitude...even after 45 years!
Retired in 1990.

Starv better Design, Reason..........Honey Comb Design with the Punched Octagon holes ...Better... Areospace Lite & Strong
Number9..........Drill holes.......Strong.... Made at Home
LOL!!!
I can see, I have a problem in "Communication"!! Let me try....

Number9."The ONLY advantage for using stainless for a sand scoop and not grade 5 titanium, is the price of the metal.''- yes,price is really big, we have titanium is 35-50USD \ kg ....
in Russian (Cyrillic) do not write it correctly displayed, I understand you.
you train of thought of another ....
not for me to praise the titanium, I know about it.

I've had a few people email me asking what gauge Grade 5 titanium to use to duplicate a scoop that's already manufactured.
If you use the same gauge, or thickness of metal, the titanium scoop would be about 45% lighter and about 45% stronger. Because the tensile strength of Grade 5 titanium is 135,000 PSI... compared to 304 stainless of 73,000 PSI
If you wanted your Grade 5 scoop to match the strength of a stainless scoop of the same design, you could use a lighter gauge metal and the Grade 5 scoop would be as strong as the stainless scoop but weigh less than half as much!
When designing a scoop, you must view not only the weight, but also how strong you wish the scoop to be.
If you just compare weight using the same gauge/thickness of metal and not realizing you've gained 45% strength Then you may asked... Why Titanium!

Number9of titanium, I agree with you-metal excellent! and stingy with it obtained excellent.
and do not lead me to only enter numbers, I know them ...
but about the stainless steel 304 will tell you that this is a bad choice for a scoop, and if you compare its parameters then all is clear ...
