Titanium Rectangular Bar

Titanium square bars have the characteristics of low density and high specific strength. It has good corrosion resistance and heat resistance, and the new titanium alloy can be used for a long time at temperatures of 600 ℃ or higher. [2-4] Titanium square bars have good low-temperature resistance and can maintain good ductility and toughness even at low temperatures ranging from -196 ℃ to 253 ℃. In addition, it also has strong anti damping performance, non-magnetic properties, tensile strength close to yield strength, good heat transfer performance, low elastic modulus, gas absorption performance, memory function, and superconducting function.

The common sizes of titanium square bars include 6 × 6mm, 8 × 8mm, 10 × 10mm, 12 × 12mm, 14 × 14mm, 20 × 20mm, 30 × 30mm, etc. The specification range can reach 1-100mm, and the longest length can reach 4000mm

The execution standards include ASTMB348,AMS4972,ASTM F67,ASTM F136,GB/T 2965-2007,GB/T 13810-2007,ASTM B381 Wait, the tolerance level can reach h9, including H11, H7, H6

The metallographic structure level can provide A1-A9; The states are divided into annealed state (M), hot working state (R), and cold working state (Y); The surface is divided into forged surface, rolled surface, polished surface, and polished surface

The basis of titanium square rod is sponge titanium, which is a porous metallic titanium obtained from titanium ore by magnesium thermal reduction or sodium thermal reduction. The purity, particle size, and impurity element content of sponge titanium directly constitute the genes of subsequent processed materials.

After obtaining sponge titanium, it needs to be melted to transform it into a machinable form. Usually, vacuum consumable arc melting or cold bed furnace melting technology is used. Melting is often carried out more than once, and multiple remelting processes are used to achieve uniform composition and eliminate defects, ultimately resulting in the casting of titanium ingots with uniform composition and dense structure. This is the matrix before the formation of the titanium square rod.

Titanium ingots need to undergo plastic deformation to become square bars. This process is mainly completed through forging and rolling. Subsequently, through a profile rolling mill, it is rolled into long bars with a square cross-section under precise temperature and pass control. The temperature, deformation rate, and cooling method during this process collectively determine the metallographic structure and mechanical properties inside the rod.
 

The detection of titanium square bars is based on product execution standards, covering tolerance, metallographic structure, product condition, and surface quality. Execution standards include GB/T 2965-2007, ASTM B348, GB/T 13810-2007, and medical standards ASTM F136/F67.

Tolerance levels usually include H11, H9, H7, H6, and the crystal phase structure level of metallographic structure can be provided as A1 to A9. Product states are divided into annealed state (M), hot working state (R), and cold working state (Y), among which annealed state products are often subjected to ultrasonic flaw detection.

The product surface can be divided into forged surface, rolled surface, polished surface, polished surface, etc.

Aerospace: Aircraft airframes, engine components, landing gear parts, and fasteners.

Medical: Surgical implants (rods, screws), prosthetic devices, and dental appliances (using Grade 23).

Chemical & Marine: Heat exchangers, condenser tubing, cryogenic vessels, and equipment for offshore platforms.

Industrial: Pickling baskets and components exposed to corrosive environments

Q1:How can I choose Grade 2 and Grade 5 Titanium Rectangular Bars?

A:Choosing between Grade 2 (Commercially Pure) and Grade 5 (Ti-6Al-4V) for a titanium rectangular bar comes down to balancing strength against fabricability and cost. There is no single "best" grade-only the best fit for your specific application.

Q2:Is titanium really biocompatible?
A:Yes. Titanium forms a stable, inert oxide layer that prevents ion release, making it non-toxic to the body. For medical use, look for conformance to ASTM F136 (Implants) or ISO 5832-3.

Q3：What size ranges are available for rectangular bars?
A:Titanium rectangular bars come in a wide range of dimensions, often customizable:

• Thickness: From very thin 0.025 inches (0.6 mm) up to 4 inches (100 mm) or more .
• Width: From 0.125 inches (3.2 mm) up to 12 inches (300 mm) .
• Length: Typically standard at 12 ft (3.6 m) or 20 ft (6 m), but suppliers can cut custom lengths

Q4: Can Titanium Rectangular Bars be welded?
A:Yes, but with strict precautions

Q5: How do I verify I am buying high-quality titanium?
A:Always request Mill Test Reports (MTRs) that certify the material meets specific standards (e.g., ASTM B348 for bars). Reputable suppliers provide full traceability from the original ingot to the final bar . Third-party inspections (TPI) are also available for large orders.

Q6: What are the typical lead times?

A: In-Stock Items: Usually ships in 3-5 working days.Custom Orders: Generally takes 10-20 working days for production.

Q7: Can I get samples before placing a large order?
A:Yes, most manufacturers provide free material samples. However, the buyer usually covers the shipping cost
