Yes, I do. Show me some objective information showing the benefits of LiquidMetal, something other than the hand-waving platitudes of Apple or on LiquidMetal’s own website.

I’ve listed the density, the Young’s modulus, the tensile strength relative to other metals, and shown it’s nothing special.

Look at the yield strength, the Young’s modulus, or the density in relation to other materials. Look at the minimum cast dimensions. Look at the cost.

Then get back when you’ve learned that LiquidMetal is a lot of hot air...

Yes, I do.

To restate the context, that's you do believe I'm "just parroting Apple's statements" and "Believing everything Apple says because they're Apple."

Okay. Now the facts. This story is here because someone found out about the license in a LiquidMetal SEC filing. That's it, no other source. There was no Apple statement to parrot, there was no Apple statement to believe. You didn't even read the story. You parrotted the old "Apple fanboi" accusation from a purposeful position of absolute ignorance.

Look at the yield strength, the Young’s modulus, or the density in relation to other materials. Look at the minimum cast dimensions. Look at the cost.

First you thought LiquidMetal was an alloy, when it's a company, and now you seem to think it is one alloy, when it's not. Like other metals, there are various alloys with differing properties.

But okay, let's look up the Young's modulus. Vitreloy-1 is about 95-105 GPa. That's much better than the currently used aluminum, and right at the bottom end of traditional titanium alloys. Sounds great for something that can be produced cheaply in bulk like thermoplastics. If Young's modulous is SO IMPORTANT to you, then bitch about Apple not using carbon nanotubes. I'd love to see the manufacturing cost on those items. However, if it ever gets cheap enough to manufacture nanotubes, I'm sure Apple will will be looking into it. And then you'll be talking about how bad nanotubes are.

More important than that in consumer electronics applications would be fracture toughness, how resistant is it to resisting the spreading of cracks (such as when dropped). These alloys can get a fracture toughness equal to steel and titanium alloys. Again, the point is you get these properties in something that can be injection molded.

Cost? Hmmm, which is cheaper for long runs, investment casting, CNC milling or injection molding? I'd have to go with the injection molding by far. Cost of materials? That's LiquidMetal's contribution, they found a way to make amorphous metals cheaply, and Apple now has the license to it.

LiquidMetal is a lot of hot air...

Not as hot as other metals, another benefit for low-cost mass production.

Time will tell. The others almost always copy Apple's manufacturing and designs. But Apple finally found a way to stop the copiers. In a couple years when they want to copy Apple's use of Vitreloy, they're going to run up against Apple's exclusive and perpetual rights to the technology in consumer electronics. Too bad.
