How to choose high-quality titanium rods: key characteristics and identification methods

一、 Appearance inspection：

1 Surface uniformity: The surface of high-quality titanium rods should be smooth and uniform, without any uneven phenomena such as pits or pockmarks. These uneven phenomena are often caused by severe wear of the rolling groove, which can affect the appearance and performance of the titanium rod.

2. Scratch condition: Check if there are any scratches on the surface of the titanium rod. Poor quality titanium rods are prone to burrs and scratches on the appearance of titanium materials due to their simple production equipment. Deep scratches can reduce the strength of titanium and affect its performance.

3. Shape and Size: High quality titanium rods should have standard shapes and sizes. Poor quality titanium bars may be thin and low, with insufficient filling, which is caused by the manufacturer adjusting the production line pressure to achieve high load service.

二、 Folding and Scaring：

1 Folding phenomenon: creases are various creases formed on the surface of titanium rods, which often run through the longitudinal direction of the product. Poor quality titanium rods are prone to folding due to the manufacturer's high pressure drop, which can cause problems such as folding ears and cracks, seriously affecting the strength of titanium.

2. Scar condition: The surface of high-quality titanium rods should be free of scars. Scars are usually caused by uneven raw materials, high impurities, and rudimentary production equipment. Scars can affect the appearance and performance of titanium rods.

三、 Cracks and Color ：

1 Texture inspection: Check for cracks on the surface of the titanium rod. Poor quality titanium rod blanks may contain many pores, which can cause cracks during the cooling process due to the influence of thermal stress. These cracks will become more pronounced after rolling, seriously affecting the strength and performance of the titanium rod.

2. Color judgment: High quality titanium rods should have a metallic luster. Poor quality titanium rods may appear light red or have a color similar to pig iron, which is caused by poor quality of the billet or non-standard rolling temperature.

四、 Cross section and strength：

1 Cross section shape: The cross-section of high-quality titanium rods should be circular or standard in shape. The cross-section of inferior titanium rods may have an elliptical or irregular shape, which is caused by the large pressure drop between the two lines in front of the roller. This shape of titanium thread greatly reduces its strength and does not meet the specifications.

2. Degree testing: The titanium rod is subjected to strength testing using professional strength testing equipment to ensure that it meets the requirements for use. Poor quality titanium rods often have low strength and cannot meet high standard usage requirements.

    In summary, selecting high-quality titanium rods requires comprehensive consideration from multiple aspects such as appearance, folding and scarring, cracks and color, as well as cross-section and strength. Only by choosing high-quality titanium rods produced by legitimate manufacturers can we ensure that the performance and quality of the product meet the requirements for use.
