10. Emergency Zone ReDo Reusable Long Lasting Pocket-Sized Hand Warmers. Non-Toxic. Great for Cold Weather, Heat Therapy, Joint, Back, and Muscle Pain, Cramps, Arthritis.
- RESUSABLE: Why keep buying new hand warmers when there is a better, more cost effective option? With Emergency Zone ReDo Reusable Hand Warmers you can simply reuse the same hand warmer over and over again. On occasion the product can be activated in transit and arrive crystalized. If that is the case simply boil to reuse. Directions: Wrap hand warmer in cloth (or place a rack on the bottom of the pot), place in boiling water, keep it immersed until crystals disappear, wait for it to cool.
- LONG LASTING: We recommend wrapping your hand warmer with a cloth during use as it extends the life to up to 2 hours. Unwrapped will give you 35-45 minutes of intense heat.
- SIZE: These non-toxic hand warmers are available in both small 3” x 5” and large 4” x 6” sizes. They also produce less waste than traditional hand warmers.
- DIRECTIONS: 1. Flex the metal chip inside to make it snap until the liquid begins to crystalize. 2. Gently knead the hardening liquid. 3. Wrap in cloth or keep in your pocket to prolong heat. 4. Enjoy the warmth!
- 100% MONEY-BACK GUARANTEE: If for whatever reason you are not 100% satisfied with your hand warmer, please contact us and we will make it right by you.

Let's see...
> ...aluminum plate to use as a laptop surface.
> I've used cheap carbon fiber in the past but found it heavy...
> ...could use the heat sinking properties of aluminum for my application.
> Literally going to be a rectangular plate of aluminum to place a laptop on. ...not be affixed to anything, ever
Well. Two things:
A) Chances are good that the aluminum plate is not going to make a measurable difference in the temperature of your laptop because it'll not have a conductive link to the heat source or provide a dramatic improvement in airflow compared to other rigid surfaces such as the "cheap carbon fiber" you mentioned.
B) Aluminum is 2-5x heavier than CF to obtain the same rigidity for this application.
If you really think about your application of supporting the laptop (presumably in your lap) while helping it cool down, then you only have two options: 1) Rigid support that does not obstruct airflow around the laptop. 2) Mechanisms that provide additional airflow.
Another logical goal here is to prevent that heat from accumulating in one's body/groin. For that reason, it's best to have an insulative layer on bottom of the surface to act as a heat shield.
Now, if you look at commercial solutions they focus on just facets 1 and 2, and most all of them consist of raised mesh surfaces with or without fans. My suggestion is buy something commercial from a bargain bin, or if you like to DIY follow a guide like this one.
I don't work with structural alloys, but I can suggest several texts that might be of interest to a structural engineer looking to study the lofty, arcane, superior art of metallurgical and materials engineering:
https://smile.amazon.com/Deformation-Fracture-Mechanics-Engineering-Materials/dp/0470527803
https://smile.amazon.com/Corrosion-Control-Revie-Winston-Hardcover/dp/B011MCRNHW/
https://www.asminternational.org/search/-/journal_content/56/10192/06542G/PUBLICATION
If you have more specific interests I can suggest others, but I don't want to bog you down in great texts on other subjects that aren't of interest to you.
I worked with just this.
I never found a single best book. Use a combination of:
If you find a single good resource I'd love to know. I ran TGA on silicone and epoxy nanocomposites daily for 3 years. I also conducted thermal conductivity testing with a custom setup. If you know the polymer chemistry you should be able to figure out the TGA profiles. However, thermal analysis alone is not sufficient if you don't know what's in your sample, you need at a minimum also FTIR (and possibly NMR and raman)
I used a combination of FTIR and TGA to answer questions about my materials, determine grafting density (polymers grafted to the ceramic nanoparticles) and more.
Good luck!
EDIT: I sifted through stacks of books at our university library and they rarely had what I was looking for. For your case that might be different.
It's unlikely that I'd need to go above 350 F, even then, that's pretty high. I'll be using it to run extraction experiments, and my primary solvents have a boiling point between 150-175F so my normal operating temperature won't be above 200F.
However, those heating elements get wicked hot, hot enough for the stainless casing to grow bright red. I wired up a voltage regulator in addition to my PID so the heating elements don't have to run at full blast, but I'd like to be able to run them on high if need be.
Ohh and I'm using an external temperature probe, so my temp readings will be based off the temp of my solution, not the plate.
The obvious choice is the introductory holy bible of MSE. If you already know the basics of how materials are categorized and behave, that book /u/Tartarus116 posted looks pretty good.
applied welding engineering
Haven't gotten all the way through it but should have a good bit of what you're looking for.
Personally, I just got a textbook on materials engineering. That covers everything you're asking and more. Or just a steel or metals textbook.
Be warned that all of those will require college algebra and a good knowledge of physics, if not calculus as well.
Edit: this looks good
This is called 'materials selection' and Ashby is the main pioneer (e.g. https://www.amazon.co.uk/Materials-Selection-Mechanical-Design-Michael/dp/0750661682 ). Otherwise, I'd say be aware for each alloy or class of alloys
Meh. This type of thing has been around for years. The only interesting part is that they nucleated crystallization optically, but honestly that's not particularly surprising either.
I can't give any advice on concrete, but I have a recommendation for steel. We used this one specific to corrosion when I took that class. There's a lot to dig into in it. Just be advised that you may want to borrow a chemistry for dummies book or keep some sort of chem reference nearby when you peruse it, because it does mention redox reactions and the like.
What about clear heat shrink tubing? https://www.amazon.com/Insultab-3010000C1A5-HS-105-Polyvinylchloride-Shrink/dp/B003ICY2H4

Maybe some spring steel? The link below you can buy different thicknesses to suit what you need.

Do you need the metal to be inside the plastic for chemical resistance or something? Or could you just use a plastic mesh and twist-tie it in place?
