Titanium Grade 4

1. Performance Comparison of Titanium Grade 4

Titanium Grade 4 (Gr4) is the strongest of the commercially pure titanium grades (Gr1–Gr4), offering an excellent combination of strength, corrosion resistance, and workability. Compared with Gr1, Gr2, and Gr3, Gr4 provides the highest tensile and yield strength among pure titanium, while still maintaining good corrosion resistance and formability.

Its high strength-to-weight ratio makes Gr4 an ideal material for critical applications that require durability and reliability under stress. Titanium Grade 4 Sheet and Titanium Grade 4 Tube are widely used in industries where both structural performance and lightweight properties are essential.

As a professional Titanium Grade 4 Supplier, Gr4 is the preferred choice when mechanical strength and corrosion resistance must be balanced in demanding applications.

2. Chemical Composition Comparison

Titanium Grade 4 is a commercially pure titanium material with carefully controlled interstitial elements that enhance its mechanical performance:

Typical composition limits include:

• Titanium (Ti): Balance

• Oxygen (O): ≤ 0.40%

• Iron (Fe): ≤ 0.50%

• Nitrogen (N): ≤ 0.05%

• Carbon (C): ≤ 0.10%

• Hydrogen (H): ≤ 0.015%

Compared with Gr1–Gr3, the higher oxygen and iron content in Gr4 significantly increases strength while slightly reducing ductility. This makes Gr4 particularly suitable for applications requiring high durability under stress, while maintaining excellent corrosion resistance.

3. Application Fields

Titanium Grade 4 is widely used across high-tech and aerospace industries due to its superior mechanical properties and corrosion resistance:

• Foldable Smartphones: Gr4 is increasingly applied in hinge components and structural frames for foldable phones, including models by Apple, Samsung, and Huawei. Its strength, lightweight nature, and corrosion resistance make it ideal for devices that undergo repeated folding.

• Aerospace Industry: Gr4 tubes and sheets are extensively used in aircraft hydraulic lines, structural tubing, and critical components requiring high strength and resistance to harsh environments.

• Chemical & Marine Applications: Excellent corrosion resistance makes Gr4 suitable for piping, heat exchangers, and marine equipment exposed to seawater or aggressive chemicals.

• Industrial Fabrication: Titanium Grade 4 Sheet is also used in precision manufacturing, medical devices, and mechanical components requiring both durability and formability.
