De­fense

Built for the Warfighter. Mach Five Labs brings precision to defense. The same discipline that holds a bearing alive inside of a reactor holds an armament component to spec in the field. We don't have two standards.

Machined
for the Field

One quality standard. Applied to everything we build. The discipline that keeps a bearing alive in a sodium reactor is the same discipline that keeps a firearm functioning in adverse conditions.

Specialized
Material Research

We don't stop at what's been qualified before. Our materials research program investigates advanced alloys, ceramic-metal composites, and novel coatings for components that must survive where conventional materials fail.

MAT-01

Nickel Superalloys

IN718, Inconel 625, Waspaloy. High-temperature strength retention, oxidation resistance. We have deep process knowledge for these notoriously difficult materials.

1000°+Celcius Rated
MAT-02

Titanium Alloys

Ti-6Al-4V, Ti-3Al-2.5V Exceptional strength-to-weight for weight-critical applications. Machined with specialized tooling strategies for superior surface integrity.

43%Lighter than Steel
MAT-03

Ceramic Composites

SiC-reinforced aluminum matrix. Boron carbide exploration. Armor-grade hardness at significant weight reduction for ballistic protection applications.
