What is Grade 1 Titanium Plate?
Grade 1 titanium plate represents the purest form of unalloyed commercial titanium available in the market. It is the softest and most ductile grade among the four commercially pure (CP) titanium grades. Because it is unalloyed, it provides the highest level of corrosion resistance and is completely non-magnetic.
For engineers and procurement managers, understanding the exact technical specifications is crucial for material selection. Below are the core properties based on the ASTM B265 standard.
The extraordinary formability of Gr1 titanium comes from its strictly controlled impurity levels. By maintaining very low oxygen and iron content, the material achieves excellent deep drawing capability, making it the perfect choice for stamping complex shapes.
Chemical Composition
| Element | Content Limit (Max %) | Impact on Material Performance |
|---|---|---|
| Nitrogen (N) | ≤ 0.03 | Minimizes brittleness and ensures structural integrity |
| Carbon (C) | ≤ 0.08 | Keeps the material soft for excellent formability |
| Hydrogen (H) | ≤ 0.015 | Prevents hydrogen embrittlement during processing |
| Iron (Fe) | ≤ 0.20 | Crucial for maintaining low hardness and high corrosion resistance |
| Oxygen (O) | ≤ 0.18 | Key Factor: Low oxygen guarantees extreme ductility and deep drawing capability |
| Titanium (Ti) | Balance | Ensures the "Pure Titanium" characteristics |
Mechanical Properties
When evaluating materials for fabrication, mechanical behavior under stress is a primary concern. The low yield strength and high elongation of Grade 1 titanium mean it can be cold-formed extensively without cracking.
| Mechanical Property | Value | Fabrication Benefit |
|---|---|---|
| Tensile Strength | ≥ 240 MPa (35 ksi) | Provides sufficient baseline strength for pressure and structural applications |
| Yield Strength (0.2% Offset) | 170 – 310 MPa (25 – 45 ksi) | Low yield strength ensures the plate is highly workable and easy to bend |
| Elongation (in 2 inches) | ≥ 24% | Outstanding high ductility, critical for severe forming operations |

Our factory
Our factory is equipped with core processing machinery for titanium products. For melting and forming, we use vacuum arc remelting (VAR) furnaces and a 2,500-ton hydraulic press. The billet processing line includes a high-temperature rolling mill and a radial forging machine capable of producing bars and rods from 8mm to 300mm in diameter. For seamless titanium tubes, we operate three-roll piercing mills and cold pilger rolling mills (LG-60, LG-90). Titanium plates and strips are produced on a four-high cold rolling mill with an online annealing furnace. For wires, we have a continuous wire drawing line with in-line degreasing and spooling units. All key equipment is CNC-controlled, ensuring consistent dimensional accuracy and surface finish for tubes, plates, bars, wires, and strips.
