How to detect titanium products are pure titanium?

Because of its health, lightness and non-allergic characteristics, titanium products have gradually developed from military applications and medical applications such as aerospace to civilian products, and are entering the lives of ordinary people.

It started with lightweight and stretchy titanium frames, and then there were lightweight and strong outdoor portable water cups, household tableware, titanium pots, and hypoallergenic accessories such as titanium buckle belts, key chains, necklaces and bracelets that were worn close to the body.

The most accurate is of course the test, followed by the spectrometer to play the spectrum, but these two are inconvenient for ordinary consumers to use. Today I have summarized several small methods for identifying titanium metal.


The first, and relatively most accurate, is to calculate density.

If it is a regular-shaped item, such as a square plate, a round bar, etc., we can easily calculate its volume, and a household kitchen scale can also weigh it. Then, density comes out. The density of titanium is 4.51 grams per cubic centimeter. As long as it is around this density, it is basically titanium. The common titanium alloy grade is TC4 titanium alloy, and the density is similar.

The second is the ceramic scratch method.

Using titanium products on white ceramics, with a little force, will leave gray scratches, and there is no convenient and easy physical method to remove such scratches. Of course, metals such as lead and tin can also be scratched on white porcelain, so it does not mean that as long as there are scratches, it must be titanium, but this can effectively distinguish stainless steel. Stainless steel will not scratch white porcelain. For metals such as lead, tin, and aluminum, although scratches can be left, the density is very different from that of titanium, and the feel of the combined weight can almost be judged.

The third is to measure the feel.
Titanium has low density, high strength and high specific strength, so pure titanium is lighter. The density of titanium is 4.51g/cm3, which is 57% of steel, but a little more than half of steel, less than twice that of aluminum, and three times stronger than aluminum. The specific strength of titanium alloy is the largest among commonly used industrial alloys. The specific strength of the alloy is 3.5 times that of stainless steel, 1.3 times that of aluminum alloy, and 1.7 times that of magnesium alloy. Pure titanium wok is about 30% lighter than ordinary iron wok.

Fourth, color contrast.
The metal color of titanium alloy is gray-white, and the color and texture are different from stainless steel and aluminum alloy. Because titanium alloys are difficult to polish and color, the surface of titanium alloy products is usually mechanically polished or frosted. There are also a few high-grade titanium alloy products that are partially polished to a mirror finish, while the mechanically polished and frosted surface color is gray or dark gray unique to titanium alloys. However, in order to make the products more ornamental, some merchants will also pass the surface treatment, without the need for painting and coloring, to make the titanium products show gorgeous colors.
