Brinell Hardness of Common Materials
Armor in Twilight2000 is compared to armor plate to determine Armor Value. Standard Armor Plate has a Brinell Hardness Rating of 500. It is stated in the Rules that 5mm of armor plate equals 1 Armor Value. Here is the Brinell Hardness Rating of other materials that you may need to determine the Armor Rating of;
Soft Wood (Pine): BH 1.6
Hard Wood (Oak to Mahogany): BH 2.6 to BH 7
Lead (Pure): BH 5
Lead (Alloyed): BH 22
Aluminum (Pure): BH 15
Aluminum (AW6060): BH 75
Mild Steel: BH 120
Stainless Steel Annealed (18-8/304): BH 200
AR500 Plate Steel/Armored Plate: BH 500
Hardened Tool Steel (Treated, Annealed): BH 600 to BH 900
Titanium: BH 700 to BH 2900
Titanium (6a1-7nb used in Aircraft/Bike Frames): BH 1600
Titanium (Enhanced/Armored): BH 2900
Synthetic Diamond: BH 4600
I hope these help you decide what protection a given material should provide.
