Titansmith Grade 5 Titanium Rods, 14mm
Diameter: 14 mm; Length: 250 mm; Package: 10 pcs. Material: Grade 5 Titanium (Ti-6Al-4V). These GR5 rods deliver very high tensile strength (≥895 MPa) and superior corrosion resistance. Best for medium-to-large components requiring a strong, lightweight bar with good fatigue resistance. Choose this if you need multiple identical length segments without frequent reordering.
Best for: Hobbyists and professionals building robust axles, pins, or fixtures where strength-to-weight matters. Caution: Larger diameter requires more robust tooling and clearance in machining setups.
Titansmith Grade 5 Titanium Rods, 12mm
Diameter: 12 mm; Length: 250 mm; Package: 5 pcs. Material: Ti-6Al-4V (GR5). High tensile strength and corrosion resistance; behaves well at elevated temperatures. Best for mid-range shafts and precision components with a balance of stiffness and weight. Choose this if you need a versatile rod for multiple small to mid-sized parts.
Best for: Engineers and model makers needing reliable strength in compact forms. Caution: Availability may be in limited pack sizes; plan ahead for future projects.
Titansmith Grade 5 Titanium Rods, 5mm
Diameter: 5 mm; Length: 250 mm; Package: 2 pcs. Material: GR5 Titanium (Ti-6Al-4V). Offers a high strength-to-weight ratio; maintains properties from cryogenic to elevated temperatures. Best for small-diameter, high-strength parts like micro-assemblies or precision fixtures. Limitations include smaller diameter suitability for heavier loads.
Best for: Small-diameter prototypes and tight-tolerance parts. Caution: 5 mm may be too small for some load-bearing applications; verify stress requirements before use.
Titansmith Grade 5 Titanium Rods, 4mm
Diameter: 4 mm; Length: 500 mm; Package: 2 pcs. Material: GR5 Titanium. Very high strength-to-weight ratio with excellent corrosion resistance across high and low temperatures. Best for fine machining and longer, slender components. Limitation: The longer length may require careful handling to avoid bending during processing.
Best for: Precision, small-diameter components, or long slender shafts. Caution: Ensure tooling supports 4 mm diameter to prevent chatter on longer cuts.
Grade 5 Titanium Round Bar Ti-6Al-4V (TC4/GR5), 35mm
Diameter: 35 mm; Length: 100 mm; Material: Grade 5 Titanium (Ti-6Al-4V). Tensile strength around 1012 MPa, lightweight with density about 4.4 g/cm3. Best for heavy-duty aerospace-like components or fixtures requiring robust load handling. Limitation: Large-diameter rods can require more powerful machining and tooling investments.
Best for: Projects needing substantial strength in a titanium rod with a larger cross-section. Caution: The 100 mm length may not suit longer assemblies without cutting or re-reaming.
Buying Guide: Grade 5 Titanium Rods In Practice
What to consider when choosing ASTM B348 Grade 5 rods:
- Diameter and length versus your part geometry and tooling capabilities.
- Strength requirements: Ti-6Al-4V offers high tensile strength and fatigue resistance; match to expected loads.
- Temperature exposure: Grade 5 performs well from cryogenic to elevated temperatures (approx. -250°C to 400°C).
- Corrosion resistance: Excellent in seawater and many chemicals; consider environment when selecting grade and coatings.
- Volume and packaging: Choose the exact piece count to minimize waste and ensure supply for ongoing projects.
