This armor is not the one tested in the video but is an example of alloy plates available for armor systems.
Titanium vs ceramic body armor.
Chobham armour is the informal name of a composite armour developed in the 1960s at the british tank research centre on chobham common surrey the name has since become the common generic term for composite ceramic vehicle armour other names informally given to chobham armour include burlington and dorchester.
The key to stopping small arms such as pistols or rifles depends not solely on hardness but also the capability of the plate to take multiple hits before it.
In armor structures ceramics are usually backed by metal plates with or without a composite layer sandwiched between them see fig.
Soft vests are made of many layers of woven or laminated fibres and can protect the wearer from small calibre handgun and shotgun projectiles and small.
The most common ceramic materials used for armor applications are alumina boron carbide silicon carbide and titanium diboride.
To add to jonathan s answer titanium is also exceptionally brittle compared to steel.
The video shows conventional steel armor with steel plates being tested using steel core armor penetrating bullets.
You ll be surprised at the result.
I m not sure that wearing around an inch and a quarter thick plate of titanium is an improvement over the thinner steel based on bulkiness but it sure does stop the rounds even a black tip 50bmg which almost made it through.
