Kudos for an engineering led solution. I have no idea what "ballistics grade aluminum" is (since nobody uses ALU for ballistics armour##), but Ti has more inherent toughness# and seems a better fit as a skid-plate. # elongation and tensile strength. ## The ballistic standard for armour (RHA) is a 1/4 steel plate. Ballistic Alu is roughly 1/2 inch or double the thickness used here, in most applications.

It's probably a reference to the increasingly common use of aluminum plate armor in military vehicles. Aluminum has some distinct weight advantages that make it ideal for light armor.

Think tanks not people. Aluminum is far cheaper than what you would put in armor vests but still light and strong. Ceramics are arguably better overall, but combining the two is a net win. Anyway, ballistic grade aluminum actually does refer to something and is probably better for cars which don't have to deal with anti tank rounds.

  Yeah, I hear you but 1/4 inch is not bulletproof. Its like saying "ballistics grade sand". Which in sufficient thicknesses, is bulletproof =D. "MIL-DTL-46027 is supplied as a 5083-H131 product. Ballistic reports are supplied for thicknesses over 0.499" per specification. Our stock range is 0.250" thru 3". Typical stock size is 72" wide x 144" long." Similar qualification for MIL-DTL-46063 REV H OR LATEST http://www.cliftonsteel.com/aluminum-armor-plate.html http://www.cliftonsteel.com/aluminum-armor-plate.html

(since nobody uses ALU for ballistics armour) The M2-series Bradley IFV uses aluminum armor. You'd think they would have learned from the Vietnam War era M113 APC that aluminum would burn readily. http://en.wikipedia.org/wiki/M2_Bradley http://en.wikipedia.org/wiki/M2_Bradley http://en.wikipedia.org/wiki/M113_armored_personnel_carrier http://en.wikipedia.org/wiki/M113_armored_personnel_carrier
