Grade 5 (Ti-6Al-4V) and Grade 23 (Ti-6Al-4V ELI) share the same base composition of 6% aluminum and 4% vanadium. The critical difference lies in interstitial element control — Grade 23 limits oxygen to 0.13% max versus Grade 5’s 0.20% max, along with tighter caps on nitrogen and hydrogen. This chemistry
Titanium is the most widely used metal in medical implants today, holding 90.99% of the global dental implant market as of 2025. Its dominance isn’t marketing hype — it stems from a rare combination of properties: a self-healing oxide surface, the ability to physically bond with living bone, and near-total
Titanium does not rust because it instantly forms a microscopic titanium dioxide (TiO₂) layer when exposed to air — a self-healing shield that stops corrosion before it starts. This passive oxide film is only 3–6 nanometers thick initially, yet it makes titanium nearly immune to seawater, salt spray, and most
Titanium is strong but not hard. In Rockwell C terms, Grade 5 titanium (Ti-6Al-4V) sits at HRC 30–34 in the annealed condition and HRC 35–39 after solution-treated-and-aged (STA). That is softer than most stainless steels and much softer than hardened tool steels. The trade-off is a strength-to-weight ratio roughly twice that of steel
Titanium thermal conductivity is approximately 21.9 W/m·K at room temperature — roughly 1/18th that of copper (401 W/m·K) and 1/11th that of aluminum (237 W/m·K). In pure thermal conductivity terms, titanium is a poor heat conductor. But that single number tells an incomplete story. Titanium’s combination of low thermal conductivity, high
Quick Summary: Titanium surface finishing encompasses mechanical polishing, chemical polishing, electropolishing, anodizing, passivation, and advanced coatings—each serving distinct performance and aesthetic goals. This guide covers complete grit progressions, Ra value specifications by industry, alloy-specific procedures, and a decision framework for selecting the right finishing method based on application, budget, and compliance
Titanium sheets offer tensile strengths ranging from 240 MPa (Grade 1 CP) to 895 MPa (Grade 5 Ti-6Al-4V) per ASTM B265 minimums, with yield strengths from 170 MPa to 828 MPa depending on grade and heat treatment. At roughly half the density of steel (4.43 vs 7.85 g/cm³), titanium sheets
Titanium stamping and forming requires fundamentally different approaches than steel or aluminum due to titanium’s high strength-to-weight ratio, low ductility at room temperature, severe springback (modulus ~114 GPa vs steel’s ~200 GPa), and tendency to gall. Five main methods exist: hot stamping (704–760°C for Ti-6Al-4V), cold stamping (limited to CP
Titanium offers an exceptional strength-to-weight ratio and outstanding corrosion resistance — but its wear resistance is surprisingly poor. Untreated Ti-6Al-4V has a Vickers hardness of only 349 HV and a specific wear rate exceeding 10⁻³ mm³/Nm in dry sliding conditions, placing it firmly in the severe wear regime. Without surface
This guide compares titanium alloys (mainly Ti-6Al-4V/Grade 5) with pure titanium (CP Grade 1-4) across mechanical properties, corrosion resistance, biocompatibility, applications, and cost. Ti-6Al-4V offers 2-3x the strength of Grade 2 CP titanium but with lowerFormability and weldability. Choose CP titanium for maximum corrosion resistance and weldability; choose Ti-6Al-4V for
Specifying the wrong titanium alloy for a high-performance project won’t just compromise your design—it can cause your manufacturing costs to spiral completely out of control. When it comes to top-tier applications like aerospace engineering, medical devices, and custom bicycle fabrication, two giants dominate the conversation: Grade 5 vs Grade 9
When selecting materials for a demanding engineering project, designers often face a classic dilemma: prioritizing ease of manufacturing or maximizing mechanical strength. If you have narrowed your options down to Commercially Pure (CP) titanium, you are likely weighing the difference between grade 2 and 4 titanium. The Quick Answer: The
