Sapphire's Durability Put to the Test Head-to-Head Against Gorilla Glass

Repair experts at uBreakiFix have examined the impact resistance, scratch resistance and strength of sapphire glass in a series of tests that were published today. The tests were designed to determine whether sapphire is suitable for use as a smartphone display.

The repair technicians conducted three different tests -- a scratch resistance comparison using a tungsten carbide drill bit, a drop test with the sapphire display of the newly released Kyocera Brigadier, and a a four-point bend test to compare the failure stress and strain of sapphire glass with that of Gorilla Glass.


The results of uBreakiFix's tests show that sapphire is significantly more scratch resistant and 25 percent stronger than Gorilla Glass, but it is much more susceptible to impacts due to its brittleness. The glass is so brittle that it shattered the first time it was dropped face down from a height of only three feet.


The technicians conclude that sapphire does not necessarily offer any advantage over Gorilla Glass, as the material's superior scratch resistance and strength is offset by its low impact resistance. Phone manufacturers that include a sapphire display may choose to employ other protective measures such as a raised bezel to help protect the phone during impact with other surfaces.

Apple is partnering with GT Advanced Technologies to produce sapphire for use in future products. The exact details on how Apple will use the material is not known, but the company is rumored to be using sapphire as a display cover in future iPhone models and possibly its iWatch wearable product.

Apple has patents on tempering sapphire, chemically and with lasers, which would make it much more impact resistant and less brittle. They are testing with regular sapphire. That would be a fair test if they compared it with regular glass instead of GG.

Interesting - sapphire shattering from a 3 foot drop.

How will the rumoured iWatch face hold up if I'm wearing it during sports and it takes a knock?

Most top end watches are made from saphire and they almost never smash

----------

I thought they tested the earlier leaks of the screens and found it not to be pure saphire so had best of both worlds

Personally I'd rather have it be more scratch resistant than impact resistant. I'm also going to have a case on my phone, which should help in drops, but the screen will always be susceptible to scratches unless you throw on an annoying screen shield.

I've had my iPhone 5 for 2 years, no screen protector and I don't have a single scratch. I don't care about it being more scratch resistant because other than having a pocket full of sand I won't scratch this screen. But I do fear I could break the screen by dropping it.

I'm willing to bet that if Apple is investing over $500M in GT Advanced for sapphire, they have a plan to make it durable enough to survive a 3-foot drop. It doesn't matter how scratch resistant your screen is if it's shattered lol.

These guys go on and on about sapphire as a screen, they just keep forgetting that Sapphire has many other uses. It is possible that apple may be on its way to build a new RF chip for there phones , since Silicon on Sapphire Chips have better insulation and are extremely good for RF chips and equipments.

Sapphire has uses in camera lens and these morons are still talking about the strength of sapphire as a screen glass.

I am sure apple will surprise them with sapphire totally different usage.
