How To Choose High-Quality Titanium Rods?
Titanium rods are common titanium products and raw materials. However, when purchasing, how can we choose high-quality titanium rods? Here are several points to consider:
Due to severe wear of the rolling groove, the surface of poor-quality titanium rods often appears uneven, with blemishes or pits.
The surface of inferior titanium materials may have scratches because the equipment used by substandard manufacturers is simple, easily producing burrs that scratch the titanium surface. Deep scratches can reduce the strength of the titanium.
Inferior titanium rods are often thin and low-quality, frequently showing dissatisfaction with their appearance. This is because manufacturers try to maximize production, putting more pressure on the first few lines of the product, resulting in lower pressure on the titanium rods, which leads to insufficient filling.
Poor-quality titanium rods are prone to folding. Folds are various creases that form on the surface of the titanium rod, often running longitudinally throughout the product. The folding occurs because substandard manufacturers have low purchase rates and high rolling pressure, causing folding during the process. After folding, the product will crack when bent, significantly reducing the strength of the titanium.
The appearance of poor-quality titanium rods is prone to scarring. This is due to uneven raw materials and high levels of impurities. Simple titanium equipment causes scarring easily after rolling.
Inferior materials are prone to cracks on the surface because their billets are substandard, containing many pores. During the cooling process, thermal stress causes cracks, which appear after rolling.
Substandard titanium rods lack metallic luster, appearing pale red or similar to cast iron. There are two main reasons for this: the billets are substandard, and the materials were not rolled at the standard temperature. The temperature of the titanium was visually estimated, leading to improper rolling, which prevents the titanium from achieving the required properties.
The cross-section of poor-quality titanium rods is elliptical, with significant pressure drops on the first two lines before rolling. This greatly reduces the strength of the titanium thread and fails to meet the dimensional standards of titanium threads.
