*It would be helpful for most of you who, if you have not yet, *go to liquidmetal.com ... This is utterly NEW...PLastic was around for decades before they found a way to mass produce products with it. The sim tool (included for a limited run with the iPhone 3G) was simply a way of doing a first production test, nothing more.
If you take the SIM removal tool that is made from Liquid Metal and use a pair of wire cutters to cut it, you will generate a very noticeable spark. *Does anyone know why? *I don't and I am curious.
well, Apple did file a patent (as seen along this thread) for some type of battery technology, but, I personally, from reading about LM think that it could have multiple uses, and, perhaps Apple filed this patent first because they saw this innovation needed the most protection....
If you read about LiquidMetal, you will see that it is a new combination of alloys and the technology/way they are able to mold these alloys. Typically metal does not mold the way plastic does and so aluminum is produced another way to make iPods and MacBook unibodies. ONE THING you will notice, if you read, is that LM can be pigmented the way plastic is, so LM will have a color that goes all the way through, unlike the color that is only on the outside surface of aluminum iPods (which can scratch off). Of course, LM may take some time (months/years) to develop to the point of using for MacBooks, but, we may see iPods and iPhones with LM backs sooner...again, if you read, you will see that LM, UNLIKE aluminum, does not block radio waves, they pass through LM, so this would be a viable solution for encasing a phone, AND have more color options, and has much more potential than previous materials. (Perhaps, on purpose, or by accident, it is highly conductive and therefore could be used for battery technology, but, I know little about this.)
Cast aluminium does exist. *Engine blocks have been made from it for the greater part of the last 3 decades.
Yes, however, casting aluminum is not like casting plastic, this process does not work to produce small, precise items such as iPhone backs or MacBook unibodies. ...again, read liquidmetal.com and you will see that metals pull away from the mold as they cool, plastic does not do this, LM works much more like plastic to mold. It would seem that molding LiquidMetal like plastic would be a more efficient, perhaps less expensive way to produce Apple's products, and be a better material, while offering more colors as well.
