1. Product Forms of Grade 5 Titanium Alloy
Titanium plate and sheet: Including cold‑rolled sheet, hot‑rolled plate, and clad plate, widely used in aircraft structures, chemical equipment, and medical devices.
Titanium bar and rod: Round bar, square bar, and forged billet for machining shafts, fasteners, valves, and mechanical parts.
Titanium tube: Seamless tube and welded tube for heat exchangers, oil/gas exploration, and fluid delivery systems.
Titanium wire: Used for welding wire, fasteners, springs, and medical implants.
Other forms: Forgings, extrusions, strips, foils, and precision castings, all commonly produced in Grade 5.
2. Theoretical Weight Calculation
The theoretical weight is calculated using the density of Grade 5 titanium alloy: 4.51 g/cm³.
Plate/sheet: Weight (kg)=Length (m) × Width (m) × Thickness (mm) × 4.51
Round bar: Weight (kg/m)=Diameter (mm)² × 0.003542 (simplified: diameter² × 0.0035)
Seamless tube: Weight (kg/m)=(Outer diameter − Wall thickness) × Wall thickness (mm) × 0.0141
3. Tolerance Standards
Global specifications commonly used for Grade 5:
ASTM B265: For plate, sheet, strip
ASTM B348: For bar and forging stock
ASTM B338: For seamless and welded tubes
AMS 4928 / AMS 4967: Aerospace‑grade bars and forgings
ISO 5832‑3: Medical implant applications
GB/T 2965, GB/T 3621: Chinese national standards for bars, plates, and forgings
Tolerances cover dimensions, thickness, diameter, straightness, flatness, and surface quality, with tighter controls for aerospace and medical grades.
