Materials

The feedstock connects 3D printing to powder metallurgy, so the full powder metallurgy material spectrum is available. Because the metal powder sits inside a binder matrix, spherical particles and powder flowability are not prerequisites.

Stainless Steel 316L

Acid-resistant austenitic stainless, suitable to 450 C and welds very well. Tensile 558 MPa, yield 224 MPa, elongation 50.9%, against ISO 22068 at 450, 140 and 40. Relative density 97 to 99%.

Stainless Steel 17-4 PH

Hardenable martensitic stainless, heat treated to H900. Tensile 1,281 MPa, yield 1,129 MPa, elongation 12.0%, against MPIF 35-MIM H900 at 1,190, 1,090 and 6.0. Relative density 96 to 99%.

Tool Steel M2

Hardenable high-speed steel with a tungsten-molybdenum matrix, for abrasive tooling, jigs and fixtures. 55 HRC as sintered and 65 HRC heat treated, against ASTM A600 at 64. Relative density 97 to 99.5%.

Titanium Ti-6Al-4V

Grade 5. Strength-to-weight, corrosion resistance and biocompatibility for aerospace, defence and medical. Tensile 1,019 MPa as sintered and 1,037 MPa after HIP, against ASTM B348 at 895. Relative density 95.5 to 98%.

Inconel 625 and custom alloys

The standard portfolio is five alloys. Anything outside it can be developed.

Inconel 625

Nickel superalloy with high strength and excellent heat and corrosion resistance, for aerospace and oil and gas. Tensile 825 MPa, yield 371 MPa, elongation 43.1%, against ASTM B443 heat treated at 690, 276 and 30.0. Relative density 96 to 99.5%.

Custom alloy development

Feedstock development on a different alloy is available, including one used only at your own plant. Tungsten heavy alloys are in the portfolio and Titanium Aluminide TiAl4822 has been released. If the alloy you need is not listed, ask.

Where these numbers come from

Values measured by a third-party test facility on parts printed on an EOS Formiga P110 and published by Headmade Materials, developer of Cold Metal Fusion. Part properties are affected by design, geometry, build orientation and post-processing. Qualify your own part before production.

Datasheets

Full composition and mechanical property datasheets are available for all five alloys. Ask us for them, or find them on the Resources page.
