How to identify pure titanium rod and titanium plate

Pure titanium rods and plates are common titanium alloy products. They are widely used in medical, aviation, aerospace, chemical and other fields. When purchasing pure titanium rods and plates, it is very important to identify their quality and performance. This blog will introduce how to identify pure titanium rods and titanium plates, as well as the characteristics and advantages of pure titanium rods

1. The method of identifying pure titanium rod and titanium plate

1. Appearance: Pure titanium rods and titanium plates look similar in appearance, but due to different manufacturing techniques, the texture and color of their surfaces will also be different. Usually, the surface of pure titanium bar is smooth and shiny, and the color is brighter, such as Grade 21 Titanium Bar, while the surface of titanium plate is relatively rough, dull, and relatively dark in color.

2. Corrosion resistance: Both pure titanium rods and titanium plates have excellent corrosion resistance, but due to different manufacturing processes and material differences, their corrosion resistance will also vary. In general, pure titanium rods are more corrosion resistant than titanium plates.

3. Material: The material of pure titanium rod and titanium plate is also very important. Generally speaking, pure titanium rod has higher purity, stronger material and longer service life.

4. As a new type of eyeglass material, titanium metal has been favored by more and more manufacturers since then. With its advantages of lightness, corrosion resistance, anti-allergy, and high fatigue resistance, titanium metal has been used as a new type of eyeglass material since it came out. It is favored by more and more manufacturers. With the development of titanium materials and the increasingly mature processing technology, many titanium plates mainly made of titanium metal have appeared on the market, such as pure titanium, b titanium, and memory titanium. Among them, the purity of the titanium plate of pure titanium material is required to reach 99.9% without gaskets, screws, stipules and leg covers) and its full name is PURETITA NIUM or Ti-P for short. However, driven by individual manufacturers, some non-pure titanium or titanium alloy materials have also carried out the above markings. In addition, some eyewear dealers and consumers lack the ability to identify pure titanium plates, resulting in consumers wearing titanium frames. Afterwards, phenomena such as titanium plate rusting and skin allergies appeared, which damaged the interests of glasses dealers and consumers. The following introduces several simple and easy methods to identify pure titanium titanium plates.

5. The most commonly used and the easiest to think of to identify titanium rods and titanium wires is to use magnets to attract them, and use magnets to do magnetic reactions to loosen the titanium plate hinges as much as possible. If the mirror legs shake under the attraction of the magnet, it means that the titanium plate is not pure titanium material, otherwise it means that the titanium plate may be made of titanium. To sum up, it is not enough to simply judge whether the titanium plate material is pure titanium from the mark, and it is necessary to combine the above methods for comprehensive evaluation, so as to identify the authenticity of the titanium plate. Usually, two thin gaskets are inlaid on the hinge part of the pure titanium mirror to separate the upper and lower hinges. Therefore, checking whether there are gaskets at the hinge is also a good way to identify whether it is a pure titanium plate. Observing the joint of the hinge from the inside of the titanium plate, you will find a small groove, which is specially designed to facilitate the removal of the gasket.

6. It is lighter by hand. This is one of the easiest ways to tell the difference between a titanium frame and a non-titanium frame. Weigh the weight by hand, usually the specific gravity of the alloy frame is about 8.9g/cm3, the specific gravity of the pure titanium frame is 4.5g/cm3, because the amount of titanium material is equivalent to half of the alloy frame. The welding mark is "step" shape; the welding of alloy materials is spot welding, observe the welding points of nose pad stem and nose pad box; the welding of pure titanium material is oxygen-free butt welding. The weld marks are in the shape of a "slope", which is one of the effective ways to distinguish titanium frames from non-titanium frames, all-titanium frames and non-all-titanium frames. Is there a gasket? Pure titanium should not make direct contact between titanium and titanium at the hinge part. Observe the joint of the hinge, otherwise it is easy to wrinkle at the joint and the opening and closing of the temples are not smooth.

2. The characteristics and advantages of pure titanium rods

1. Excellent chemical inertness: Pure titanium rods have good inertness to most chemical substances and are not easy to chemically react with other elements. This makes Grade 21 Titanium Bar have extremely high corrosion resistance, and can be widely used in seawater environment, chemical production and other fields.

2. Good strength and plasticity: The strength and plasticity of pure titanium rods are relatively good, and various shapes can be manufactured, which are suitable for use in different occasions.

3. Good processing performance: pure titanium rods are relatively easy to process, weld and braze, making the processing process very flexible.

4. Light weight and high strength: The density of pure titanium rod is only about 4.5g/cm3, which is lighter than other metal materials such as copper, iron, stainless steel, etc., but its strength is very high, and it is an extremely important structural material.

In general, the identification of pure titanium rods and titanium plates needs to consider factors such as appearance, corrosion resistance, and materials. Pure titanium rod has the advantages of excellent chemical inertness, good strength and plasticity, good processing performance, light weight and high strength, and is an important structural material. The Grade 21 Titanium Bar is more superior in performance and purity, and is a more advanced titanium alloy bar.
