I created subclass for ArmorMaterial, but it isn't a class, ArmorMaterial and ItemTier are Enum, so, how I can create new materials?

Material (blocks) is final class, so I can't create a subclass for Material.

EnumHelper.addToolMaterial() and EnumHelper.addArmorMaterial() might be good to look at.

 

You're just doing tool/armor materials right?  If you need a block material as well, it uses a different approach.  All 3 are different things.

In 1.13 EnumHelper is not exist

Create an Enum Class that implements IItemTier and copy everything from ItemTier and define your custom material type

 

It can be done like this

Spoiler

public enum ItemModTier implements IItemTier
{
    ZIP(3, 500, 8.0F, 4.0F, 12,() -> { return Ingredient.fromItems(ModItems.ZIP); });

    private int harvestLevel;
    private int maxUses;
    private float efficiency;
    private float attackDamage;
    private int enchantability;
    private LazyLoadBase<Ingredient> repairMaterial;

    ItemModTier(int harvestLevel, int maxUses, float efficiency, float attackDamage, int enchantability, Supplier<Ingredient> ingredient)
    {
        this.harvestLevel = harvestLevel;
        this.maxUses = maxUses;
        this.efficiency = efficiency;
        this.attackDamage = attackDamage;
        this.enchantability = enchantability;
        this.repairMaterial = new LazyLoadBase<>(ingredient);
    }

    @Override
    public int getMaxUses() { return this.maxUses; }

    @Override
    public float getEfficiency() { return this.efficiency; }

    @Override
    public float getAttackDamage() { return this.attackDamage; }

    @Override
    public int getHarvestLevel() { return this.harvestLevel; }

    @Override
    public int getEnchantability() { return this.enchantability; }

    @Override
    public Ingredient getRepairMaterial() { return this.repairMaterial.getValue(); }
}
