Chung Metal Producer & Suppliers in Da Nang, Vietnam, supplies high-strength Titanium Grade 4 Bars and Rods that meet the highest strength requirements among commercially pure titanium grades. Our Grade 4 titanium products are best suitable for aerospace, chemical, and industrial applications where mechanical strength and corrosion resistance are both essential. With testing carried out in-house and control over dimensions, Chung Metal assures conformance to international quality standards. We offer quick delivery and custom machining for customers looking for dependable titanium solutions for pressure vessels, medical components, and marine structures in harsh operating conditions.
Titanium Grade 4 consists of ~99.2% titanium with greater oxygen (≤0.4%) and iron (≤0.5%) content than other CP grades. This provides it with the highest strength among CP titanium: tensile strength ~550–600 MPa, yield strength ~480–550 MPa, and elongation ~15–18%. Hardness is 130–160 HB. Density is still ~4.51 g/cm³. It has very good corrosion resistance, albeit slightly less than Grade 1. It has good weldability, moderate formability, and very good resistance to fatigue and erosion, which suit it well for load-bearing and pressure-rated applications.

Titanium Grade 4 Bars and Rods are composed of 90% titanium, 6% aluminum, and 4% vanadium, offering excellent strength, corrosion resistance, and durability.
Yes, Titanium Grade 3 has good weldability, making it suitable for various applications where welding is required.
Titanium Grade 4 Rods and Bars find their application in high-strength areas like hydraulic tubes, aircraft parts, orthopedic implants (e.g., dental appliances), and chemical plant heat exchangers. They are resistant to chlorides and seawater, making them suitable for equipment intended for use in the marine environment, such as propeller shafts, rigging, and offshore platforms. Grade 4 is employed in aerospace for engine casings and frames. It also has uses in high-pressure piping, industrial gas handling, and in cryogenic tanks. Biocompatibility allows for use in orthopedic devices. Grade 4 is utilized when both strength and corrosion resistance are essential in dense and lightweight designs.
