The Perfect PMTi Part

suppressors manufacturing rendering
suppressor manufacturing effective density rendering

The Concept of “Effective Density”

The less material in the total “envelope” of the part, the more material cost savings are possible with powder mettallurgy.

In this example, the final part only occupies 6% of the total envelope part and weighs 5 g.

PMTi - A Material Advantage for Suppressor Baffles

Slightly elevating the oxygen increases tensile properties via interstitial strengthening.

This strengthening mechanism is compositional rather than microstructural and persists at higher temperatures, delivering improved creep performance over conventionally formed titanium

Lamellar structure provides better creep strength than wrought or cast product.

Elevated oxygen also provides slight increase in hardness (~40HRC), which can improve wear resistance.

Tensile strengths compare favorably with ELI and NI Grades, elongation slightly less.

Material Compliance: PMTi Ti-6Al-4V

Praxis Typical PM values compare well with standard specifications

Standard PM material is best value for suppressor components

Heat treated PM material has exceptional performance

Praxis’ typical values surpass both the cast & wrought strength  specifications
