ASTM F67 Gr1 Titanium Rod Description
ASTM F67 Gr1 Titanium Rod is a surgical implant-grade α-type commercially pure titanium rod, complying with ASTM F67 standard (for surgical implants), and it is the purest grade of industrial pure titanium in medical and high-precision fields.
Chemical composition: Ti ≥ 99.5%, with extremely low impurities (Fe, O, C, N, H), ensuring excellent biocompatibility.
Key characteristics: Best ductility and formability among commercial pure titanium; easy to cold-form, bend and weld; lower strength than Gr2/Gr4; excellent corrosion resistance (especially to physiological fluids) and low-temperature toughness (no cold brittleness).
Rod form: Mainly round rods (most common), square rods, hexagonal rods; produced by hot rolling, forging and cold drawing.
Main applications: Medical field (non-load-bearing bone plates, bone nails, dental implants, orthodontic wires, surgical instruments); aerospace field (ultra-low temperature structural parts, precision non-magnetic components).
