"Properties of Wrought Aluminum and Aluminum Alloys: 7039", Properties and Selection: Nonferrous Alloys and Special-Purpose Materials, Vol 2, ASM Handbook, ASM International, 1990, p. 109-111. Mechanical and ballistic properties of powder metal 7039 aluminium alloy joined by friction stir welding
Armor Holdings was founded in 1969 as American Body Armor and Equipment, Inc. [2] at Jacksonville, Florida. In January 1996 the company underwent a change in control; Kanders Florida Holdings, Inc. and others purchased the stock held by the company's two largest shareholders. The Armor Holdings, Inc. name was adopted on August 21, 1996. [2]
In 2014, by contrast, the US ranked sixth in primary aluminum production, and provided only 3.5% of world production. US production of primary aluminum peaked in 1980 at 4.64 million metric tons. Since then, US primary aluminum production has fallen by more than half, but secondary production has increased, making up much of the difference.
One application for this alloy is in aircraft armor, where it has equivalent ballistic characteristics to AA 7039, and a reduced susceptibility to stress corrosion cracking as compared to AA 5083. [2]: 3-202 AA 2519-T87 plate is weldable using AA 2319 filler. [2]: 3-202
For example, the T-64 turret had a layer of ceramic balls and aluminum sandwiched between layers of cast steel armour, [10] whilst some models of the T-72 features a glass filler called "Kvartz". The tank glacis was often a sandwich of steel and some low density filler, either textolite (a fibreglass reinforced polymer) or ceramic plates. [ 11 ]
Advanced Modular Armor Protection (AMAP) is modular composite armour concept, developed by the German company IBD Deisenroth Engineering, since 2019 part of Rheinmetall Protection Systems. According to IBD AMAP is a 4th generation composite armour, making use of nano-ceramics and modern steel alloy technologies. [ 1 ]

The advanced Kontakt-5 explosive reactive armour on this T-90S is arranged in pairs of plates, giving the turret its prominent triangular profile.. An element of explosive reactive armour (ERA) is made of either a sheet or slab of high explosive sandwiched between two metal plates, or multiple "banana shaped" rods filled with high explosive which are referred to as shaped charges.
