What is Titanium?
Titanium is a lightweight, strong, and highly corrosion‑resistant metal. It naturally forms a protective oxide layer that keeps it from rusting, even in saltwater or harsh environments. Because of these properties, titanium is widely used in aerospace, medical implants, and high‑performance products — including writing instruments.
Why Use Titanium?
- Lightweight: About 40% lighter than steel while offering comparable strength.
- Strong & Durable: Holds up under stress, ideal for precision mechanisms.
- Corrosion Resistant: Does not rust, even with sweat, water, or salt exposure.
- Biocompatible: Safe for skin contact and non‑allergenic.
- Premium Feel: A unique balance of strength and low weight with a clean, modern look.
How we use it: We machine both Grade 5 and Grade 9 titanium.
We use Grade 9 for most pen bodies, and
Grade 5 for nearly everything else (clips, bolts, and internal mechanisms).
Grade 5 vs. Grade 9 Titanium
Grade 5 (Ti‑6Al‑4V)
- Composition: ~90% Ti, 6% Al, 4% V.
- Strength: The most common high‑strength titanium alloy.
- Characteristics: Excellent strength‑to‑weight ratio, good machinability for small precision parts, can be heat‑treated.
- Our Use: Clips, bolts, screws, mechanisms — anywhere maximum strength and wear resistance are needed.
Grade 9 (Ti‑3Al‑2.5V)
- Composition: ~94% Ti, 3% Al, 2.5% V.
- Strength: Stronger than commercially pure titanium; more ductile and formable.
- Characteristics: Great balance of strength, toughness, and workability — excellent for long, thin‑walled shapes.
- Our Use: Pen bodies, where consistent wall thickness, straightness, and surface finish matter most.
