Industry information
How to purchase high-quality titanium rods is very important. However, accurately distinguishing the quality of titanium rods is a process that requires professional knowledge and careful observation. Below, we will analyze in detail how to distinguish the quality of titanium rods from multiple aspects and perspectives.
1、 Observe the surface condition
Matte surface phenomenon: The surface of fake and inferior titanium rods often has a rough surface due to severe groove wear, resulting in irregular unevenness on the surface of the titanium material. Therefore, when making a purchase, special attention should be paid to whether the surface is flat and smooth.
Scratch marks: Fake and inferior titanium rods are prone to scratches during production and transportation, which are often caused by rudimentary equipment or improper operation. Deep scratches can reduce the strength of titanium materials and affect their effectiveness.
2、 Check the cross-section and reinforcement section
Thin and low transverse bars: The transverse bars of fake and inferior titanium rods are usually thin and low, and there is often a phenomenon of insufficient filling. This is due to the manufacturer's pursuit of negative tolerance, resulting in excessive reduction in the first few passes during the rolling process.
Folding problem: Folding is a line defect formed on the surface of the titanium rod, which runs through the entire longitudinal direction of the product. Due to the pursuit of high efficiency and excessive compression, fake and inferior titanium rods are prone to producing earrings and folding during the next rolling process. Folding products are prone to cracking after bending, which seriously affects their strength.
3、 Pay attention to color and luster
Color and luster: High quality titanium rods should have a metallic luster, while counterfeit titanium rods may appear light red or a color similar to pig iron. This is usually due to uneven raw materials, high impurities, or non-standard rolling temperatures.
4、 Observe surface defects
Scaring phenomenon: The surface of fake and inferior titanium rods is prone to scarring, which is caused by impurities in the raw materials or rudimentary equipment leading to impurities adhering to the rolling mill and producing scars. Scaring can affect the appearance and performance of titanium rods.
Crack problem: Cracks may also appear on the surface of counterfeit titanium rods, mainly due to their raw material being adobe and having many pores. During the cooling process, cracks are prone to occur due to thermal stress, and cracks are formed after rolling.
5、 Check size and shape
Cross section shape: The cross section of counterfeit titanium rods may be elliptical rather than standard circular or square. This is due to the manufacturer using a larger pressing amount in the first two passes of the finished product roller in order to save materials. This shape of titanium rod not only affects aesthetics but also reduces strength.
When selecting titanium rods, it is important to carefully observe their surface condition, inspect the cross-section and ribs, pay attention to color and gloss, and observe surface defects. Only by fully understanding and mastering these identification skills can we ensure the purchase of high-quality titanium rod products.
