In recent years, titanium products have gradually expanded from aerospace and other military applications and medical applications to civilian products due to their health, simplicity, and non-allergic characteristics, and are entering the lives of ordinary people.

It started with a simple and elastic titanium frame, followed by lightweight and sturdy outdoor portable water cups, household tableware, titanium pots, as well as anti-allergic accessories such as titanium buckle belts, keychains, necklaces and bracelets that were worn close to the body, and the varieties of titanium civilian products, With more and more styles, customers have more choices, and at the same time they start to hesitate: How do I know if the things I buy are really made of titanium? Is it pure titanium or a titanium alloy?

So, how do you know if the product you bought is made of titanium? The precise one is, of course, testing, followed by spectroscopy, but both of these are inconvenient for ordinary customers to use. The following titanium cups, titanium vacuum cups, titanium glass cup manufacturers summarize a few small methods to identify titanium products.

One, which is relatively accurate, is to calculate the density.

Assuming it is a regular rectangular object, such as a square plate, a round bar, etc., we can calculate its volume more conveniently, and a household kitchen scale can also weigh it. Then the 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 trademark of titanium alloy is TC4 titanium alloy, and the density is similar.

Two, ceramic scratch method.

Using titanium products on the white ceramics, apply a little force and make a scratch, it will leave a gray scratch, and there is no convenient and easy physical method to remove this kind of scratch. Of course, metals such as lead and tin can also make marks on white porcelain, so it does not mean that only scratches are necessarily made of titanium, but this can be useful to differentiate stainless steel. Stainless steel will not leave scratches on white porcelain. As for metals such as lead, tin, aluminum, although they can leave scratches, the density is very different from that of titanium, and the hand feel combined with weight can almost be distinguished.

What needs to be reminded is that for some titanium chopsticks, for a better customer experience, the head of the chopsticks is specially hardened, so that no scratches are simply left. Then you can try to use the tail to scratch.

Three kinds, burning method.

Assuming that there are no plastic parts that are afraid of high temperature, and you don’t mind the appearance of the product, you can burn it on a gas stove. It will turn red after a few seconds, then turn purple, blue, off-white, and continue to burn. Appears in gold, green, rose red, etc. The change of color is also related to the thickness of the product, which is different.

This method is suitable for unplated titanium products. If there is an electroplated layer, such as gold plating and silver plating, there is no way to burn the above colors.

There are also very precautionary customers who are worried that the surface is coated with titanium. Then, you can also use sandpaper to throw off the surface and burn it again.
