Round tensile specimens can be prepared from a range of engineering materials as long as the material can be turned, shaped, and held within a defined gauge section. These include:

• Metals and alloys: carbon steel, stainless steel, aluminum, titanium, copper alloys, and nickel-based superalloys.
• Composites: carbon-fiber or glass-fiber reinforced rods and hybrid laminates.
• Polymers and plastics: thermoplastics and thermosets suitable for precision turning.
• Other solid materials: sintered metals or research-grade test materials.

Each material type may require different cutting speeds, tooling inserts, and coolant flow settings to maintain consistent surface finish and dimensional accuracy. The systems we provide, including partner-built solutions, are designed to handle different hardness levels and cutting requirements while keeping dimensions consistent across all prepared samples.
