ADVANCED ALLOYS

Advanced Alloys

Diamond Age produces highly-engineered steel, magnesium, tantalum, and tungsten alloys on a small-batch basis, often via powder metallurgical techniques.  These alloys are optimized and intended for use in armor applications — particularly in applications where a combination of performance, toughness, a long service life, and resistance to punishing environmental conditions are required.

Information on our revolutionary magnesium, tantalum, and tungsten alloys is forthcoming.  Contact us for more details.


Carapace DHS

Carapace dual-hardness steel is a specially-treated steel with a surface hardness of 688 HB, a core hardness of 560 HB, and a nanocrystalline twinned plate martensitic grain structure.  It offers extremely high ballistic performance, impressive deformation capacity, and possesses the ability to absorb impressive punishment.  In annealed form, it can be formed into complex shapes, including multi-curve body armor plates — and shapes far more complex than that.

Due to post-hardening processing treatments, Carapace DHS is supplied in fully hardened condition.

Bulk properties (typical):
Hardness: 55 HRC (core) – 63 HRC (surface)
Ultimate Tensile Strength:  > 2005 MPa
Yield Strength: > 1400 MPa
Elongation:  > 14%
Charpy impact: > 28 J
Microstructure:  Martensitic, ~3% retained austenite

A Carapace DHS plate thinner than 3.7mm will stop the 7.62x39mm PS Ball.

Carapace BP

Carapace BP is a specially-processed, non-martensitic armor steel, with a tensile strength that can attain values over 3000MPa — making it one of the strongest bulk materials on Earth.   It is ideal for use in thin laminate systems, in standalone sheets for anti-blast and anti-frag applications, and towards specialty applications where the highest performance-to-weight ratio is required.  Indeed, Carapace BP is highly competitive with composite materials such as aramid and UHMWPE, even on a weight basis.  

Due to post-hardening processing treatments, Carapace BP is supplied in fully hardened and strengthened condition.

Bulk properties (typical):
Hardness: 53 HRC 
Ultimate Tensile Strength:  2900-3000+ MPa
Yield Strength: 2500 MPa
Elongation:  > 9%
Charpy impact: > 40 J
Microstructure:  Proprietary


Carapace MNB

Carapace MNB is a manganese-boron armor steel.  It’s key advantage lies in its ability to be formed to complex geometries, including deep-drawn parts, without risk of fracture, distortion, or excessive thinning.  Its ballistic performance against ball rounds is very good, and it is also suitable towards use in structural load-bearing parts.   Carapace MNB is currently seeing use in large commercial armor projects.
 
Bulk properties (typical):
Hardness: 50 HRC 
Ultimate Tensile Strength:  1700 MPa
Yield Strength: 1350 MPa
Elongation:  > 7%
Charpy impact: > 40 J
Microstructure:  Martensitic, ~1.5% retained austenite
