Why Choose Titanium?
Titanium isn’t just a metal—it’s a game-changer for industries where failure isn’t an option. From jet engines racing through the stratosphere to life-saving implants in the human body, titanium delivers unmatched performance. Here’s why innovators choose titanium.
- Strong
- Super Lightweight
- Non-magnetic
- Oxide resistance
- Ductile and malleable when heated
- Burns at high temps
- Biocompatibility
- High energy absorption
- Bio-interfacing
- Low adhesion
- Limited condensation
- Erosion resistance
How To Get Different Colors?
Titanium anodizing grows a thin oxide layer on the surface. Light bends and reflects through this layer, creating colors through light interference (like oil on water!). Higher voltage = thicker oxide layer = different colors.
Voltage-to-Color Cheat Sheet
| Voltage Range | Color Palette |
|---|---|
| 10–20V | Gold, Bronze, Champagne |
| 25–50V | Purple, Blue, Teal |
| 50–80V | Green, Turquoise, Magenta |
| 80–110V | Pink, Yellow, Electric Blue |
Note: Exact hues vary with titanium grade, surface finish, and electrolyte (e.g., baking soda vs. sulfuric acid).

Finishes and Post-Processing Options
We offer a wide range of surface finishes applicable to titanium.
Titanium anodizing is an electrochemical process that creates vibrant, durable colors on titanium surfaces by controlling the oxide layer’s thickness via applied voltage. This non-toxic, eco-friendly treatment enhances both aesthetics and functionality.
Color Spectrum & Voltage Control
Voltage Range: Colors are determined by the voltage applied during anodizing (typically 10–110V):
- Gold/Yellow: 10–20V
- Purple/Violet: 20–30V
- Royal Blue: 30–50V
- Teal/Turquoise: 50–70V
- Pink/Rose Gold: 70–90V
- Green/Deep Blue: 90–110V
- Custom Patterns: Masking or multi-voltage techniques create gradients, stripes, or logos.
Bead blasting is a surface finishing process used in CNC turning to clean, polish, or texturize a metal surface by blasting it with spherical media, typically glass beads. This process is commonly used to enhance the appearance and performance of CNC-turned parts.
Bead blasting effectively removes surface contaminants, such as dirt, scale, and oxidation, resulting in a clean and pristine surface.
In one word, bead blasting hides minor machining marks, improves tactile feel and aesthetic consistency.
A tumbled finish is a surface treatment method used to smooth, deburr, and refine machined or fabricated parts by placing them in a rotating barrel (tumbler) filled with abrasive media. This process is ideal for achieving a uniform, matte texture while removing sharp edges and minor imperfections.
1. Process:
Parts are loaded into a tumbler with abrasive pellets, ceramic chips, or polishing compounds. The barrel rotates slowly (typically 10–50 RPM) for hours or days, depending on the desired finish. Friction between the parts and media gently wears down surfaces, edges, and burrs.
2. Surface Result:
Smooth, Satin-like Texture: Non-reflective, even appearance with softened edges.
Deburring: Removes micro-burrs left by machining or stamping.
PVD (Physical Vapor Deposition) is an advanced thin-film coating process used to apply ultra-durable, decorative, or functional layers to materials like metals, plastics, and ceramics. It involves vaporizing a solid material in a vacuum chamber and depositing it as a thin, uniform coating on the target substrate.
The coating material (e.g., titanium, chromium, zirconium) is vaporized via sputtering (ion bombardment) or thermal evaporation (high-temperature heating), vaporized atoms condense onto the substrate, forming a dense, adherent layer (typically 0.1–5 μm thick).

Frequently Asked Questions (FAQs)
Why is Titanium Challenging to Machine?
Titanium’s high strength-to-weight ratio, low thermal conductivity, and work-hardening tendency make it notoriously difficult to machine.
Key Challenges:
- Heat buildup causing tool wear.
- Chip evacuation issues leading to recutting.
- Galling and adhesion on cutting tools.
Here is the Solutions:
- Use carbide tools with TiAlN/TiCN coatings (e.g., Kennametal KCU10).
- Optimize coolant flow (high-pressure through-tool systems).
- Reduce cutting speeds (< 60 m/min for roughing).
Which Titanium Grade is Best for CNC Machining?
| Grade | Properties | Machinability | Common Uses |
|---|---|---|---|
| Grade 2 | Pure Ti, ductile | Excellent | Medical implants, marine parts |
| Grade 5 (Ti-6Al-4V) | High strength | Moderate | Aerospace, automotive |
| Grade 23 | ELI (Extra Low Interstitials) | Poor | Medical devices |
Pro Tip: Grade 2 is easiest for complex geometries; Grade 5 requires rigid setups.
How to Reduce CNC Machining Costs for Titanium Parts?
Design Optimization:
- Avoid thin walls (<1.5mm) to minimize vibration.
- Use standard tolerances (IT8-IT10) unless critical.
Tooling Strategy:
- High-efficiency milling (HEM) with trochoidal toolpaths.
- Tool recycling programs (e.g., Sandvik Coromant PrimeTurning™).
Material Savings:
Near-net-shape preforms (forgings or wire-arc additive parts).
What Tools & Parameters Work Best for Titanium?
Tool Recommendations:
- End mills: 4-6 flutes, 30° helix angle (e.g., Iscar HELIDO series).
- Inserts: Positive rake geometry, sharp edges.
Cutting Parameters:
- Speed: 20–60 m/min (varies by grade).
- Feed: 0.1–0.2 mm/tooth.
- DOC: 0.5–2× tool diameter.
Critical Note: Always prioritize chip control over speed.
How to Prevent Titanium Fire Risks During Machining?
Titanium chips are flammable under high heat. Mitigate risks with:
Coolant: Water-soluble fluids (5–10% concentration).
Chip Management:
- High-pressure coolant (>1,000 psi) to break chips.
- Avoid dry machining for prolonged operations.
Shop Safety:
- Class D fire extinguishers on-site.
- Regular chip bin emptying.
