ACF always had RHA as its armor material for each part of a tank, meaning limited mechanics with some round types like HEAT, or making some fake composite armor just adjusting its health. ACE instead, brings you another 5 different types of materials that will bring you some benefits with them. This page will talk about materials that ace uses.

Outdatet, use menu information instead.

To change the material, go to the "Armor Properties" tool and choose the desired material in a box called "Material"

But before proceeding... the glossary

Type	Description
Year	The year
Curve	Defines how effective is increasing the armor thickness. Any value below 1 means loss
Mass Multipler	A multipler for Mass. RHA scaled
KE Protection	How many times is good vs Kinetic Penetrators. RHA scaled
CHEMICAL Protection	How many times is good vs Shaped charges. RHA scaled

Rolled Homogeneous Armor (RHA)

This is the default armor of ACF2 in ACE, simply rolled steel made as basic armor for most of vehicles.

Year	Curve	Mass Multipler	KE Protection	CHEMICAL Protection
1900	1	1x RHA	1x RHA	1x RHA

Cast Homogeneous Armor (CHA)

This material is a bit heavier but higher ductility version than RHA, it resists more damage than RHA, but tends to spall more and its armor is 2% less efficient than rha.

Year	Curve	Mass Multipler	KE Protection	CHEMICAL Protection
1930	1	1.25x RHA	0.98x RHA	0.98x RHA

Ceramic

As the name says, this light and fragile material will make any prop brittle against any projectiles, yet it's ideal for dealing with kinetic rounds like apds variants, but tends to break easily.

Year	Curve	Mass Multipler	KE Protection	CHEMICAL Protection
1955	0.95	0.8x RHA	2.4x RHA	2.4x RHA

Rubber

A very effective material against shaped charge rounds, but useless against kinetic rounds

Year	Curve	Mass Multipler	KE Protection	CHEMICAL Protection
1955	0.95	0.2x RHA	0.02 RHA	3x RHA

Explosive Reactive Armor (ERA)

This type of material will make props explode when hit, destroying/reducing lethal shots, being highly effective vs shaped rounds like HEAT and effective vs kinetic rounds, however, ERA is explosive and will damage nearby props if detonated, it can also be easily destroyed by low caliber shots.

Year	Curve	Mass Multipler	KE Protection	CHEMICAL Protection
1955	0.95	2x RHA	2.5x RHA	8x RHA

Aluminium

A low-cost and lighter version of RHA, meant as an replacement for low ton vehicles like afv, ifv, etc. its extremely vulnerable vs both kinetic and shaped rounds so use it for saving weight only.

Year	Curve	Mass Multipler	KE Protection	CHEMICAL Protection
1955	0.93	0.221x RHA	0.34x RHA	0.34x RHA

Textolite

As known as fiberglass, this chemical material is good vs shaped rounds and its very durable to constant shots, even if its penetrated. But dont expect effectiveness vs kinetic rounds.

Year	Curve	Mass Multipler	KE Protection	CHEMICAL Protection
1955	0.94	0.35x RHA	0.5x RHA	1.2x RHA
