Grade 1 Japanese Titanium, also known as Commercially Pure Titanium (CP-Ti Grade 1), is the softest and most flexible of the commercially pure titanium grades (Grades 1–4). It has at least 99.5% titanium and small amounts of oxygen, nitrogen, carbon, hydrogen, and iron. This high purity makes it very resistant to corrosion, easy to shape, and easy to weld, which makes it perfect for tough environments.

In summary, Grade 1 titanium combines light weight, toughness, and unmatched corrosion resistance, making it the material of choice for engineers requiring long-term reliability and excellent formability in critical applications.

FAQ
Q: Is Japanese Grade 1 titanium actually pure titanium?
A: Yes. Like all GR1, it's commercially pure (approximately 99.5% titanium). The "Japanese" refers to the mill of origin, not a different chemical formula.
Q: Is Japanese GR1 stronger than regular GR1?
A: No. Strength is determined by oxygen content and processing. Japanese GR1 typically has oxygen on the lower end of the spec, which actually makes it slightly softer and more ductile-not stronger.
Q: Why is Japanese titanium more expensive?
A: Higher manufacturing standards, tighter quality control, better surface finishes, and full traceability. You're paying for consistency, not magic.
Q: Can I weld Japanese GR1 to regular GR1?
A: Yes. They're the same material grade. Use standard titanium welding procedures (100% argon shielding, clean environment, proper filler metal).
Q: Does Japanese GR1 rust or corrode?
A: No. Like all GR1, it's completely corrosion-resistant in saltwater, chlorine, and most acids. The oxide layer is self-healing.
Packaging
Anti-Corrosion VCI Paper: Wrapped individually to protect the surface finish.
Custom EVA Foam: For smaller parts and precision components, we use laser-cut foam inserts to prevent movement during transit.
Double-Walled Cartons: All shipments go out in reinforced boxes rated for heavy freight to ensure your investment arrives in perfect condition.
Our Facility & Equipment
We manufacture in-house using German-engineered CNC lathes and milling centers. Our factory floor is equipped with:
Vacuum Annealing Furnaces: To ensure zero surface contamination during heat treatment.
Laser Inspection Systems: Every batch is measured to ensure dimensional accuracy within 0.01mm.
Clean Room Assembly: For our medical and food-grade products, final assembly happens in a controlled environment to prevent particulate contamination.
