Aluminum alloys have excellent corrosion resistance. They are sensitive to high temperatures in the range of 200 to 250°C (392 to 482°F), and could lose some of their strength.

Tungsten hot-work steels are of different types, namely, H21 to H26 types. These steels have similar characteristics to that of high-speed steels. The primary alloying elements of tungsten hot-work steels include tungsten, chromium, carbon, and vanadium.

Alloy steels comprise a wide range of steels having compositions that exceed the limitations of Si, Va, Cr, Ni, Mo, Mn, B and C allocated for carbon steels. These steels contain elements such as chromium, cobalt, nickel, etc.

Molybdenum high speed steels are designated as Group M steels according to the AISI classification system. Over 95% of high-speed steels manufactured in the US are group M steels.
Alloy steels are designated by AISI four-digit numbers. They comprise different kinds of steels having composition exceeding the limitations of B, C, Mn, Mo, Ni, Si, Cr, and Va set for carbon steels.
AISI 1040 carbon steel has high carbon content and can be hardened by heat treatment followed by quenching and tempering to achieve 150 to 250 ksi tensile strength.

Ferrofluid sounds like a concept straight from a bad science-fiction film – a black, shape-shifting metallic liquid, that moves and forms spikes using magnetic fields.
