Physical properties

Neutral Matter is a white metal made of highly condensed neutron star material. The neutrons are closely packed together, leaving no space within it.
Its mass is shifted into a parallel dimension; this allows Neutral Matter to have the durability of neutron star material at room temperature and with a microscopic fraction of its weight.
As discovered by Noriko Null, Neutral Matter can destabilized by a specific electromagnetic pulse that will restore the full mass of the material: a spoonful of destabilized neutral matter will have the weight of a mountain.

Strength

Neutral Matter is typically considered indestructible, capable of withstanding a seemingly unlimited amount of pressure. The only being shown to be capable of physically breaking Neutral Matter is the reality warping Tiamat.
Despite its fame, Neutral Matter is not completely impervious to heat: it has a melting point of 30,000,000°C.

Alternate forms

In addition to regular Neutral Matter, Hephaestus also created two alternate forms:

Heaven-Slayer: a sword forged by Hephaestus as protection against a possible Talos rebellion. Sharp enough to cut through regular Neutral Matter.

Degenerate Neutral Matter: forged by Hephaestus as a superior form of Neutral Matter and used for the armor and sword of Ares. It is durable enough to withstand the heat and pressure of a point-blank supernova, but it retains the original weight: the sword alone has the same weight of the entire Earth.
