"The world of titanium is really exciting," said Cao Chunxiao, an academician of the Chinese Academy of Sciences, in several reports. In the past, people once thought that titanium is a rare metal. In fact, it is not. It ranks among the top seven in earth metal content, higher than common metals such as copper and zinc. Titanium also plays an important role in various fields such as land, sea and air. In marine engineering, titanium's strong corrosion resistance makes it as new in the sea for hundreds of years, and does not rust; in the aerospace industry, titanium can be made into the "skeleton" and "coat" of fighter aircraft and spacecraft. High temperature attack; In the chemical and pharmaceutical industry, titanium is stable, corrosion-resistant and non-toxic, making it a necessary material for many devices. No one is more familiar with the application of titanium in surgical operations. In the operation of bone healing, if titanium is used instead of conventional stainless steel implants, titanium metal sheets can be fitted to the joints to assist growth without removing them, and it does not increase the pain of patients in the later stage of healing. Therefore, titanium has also been praised as the "most Pro-metals. "

Titanium has been widely used in the titanium era-pure titanium household products, as the darling of the new era, have quietly come to our lives. Take our commonly used electric kettles and thermos cups as an example. The hot water tea in a stainless steel container can irritate the irony smell because the iron ions of the container material are dissolved in the water at high temperatures. The main components of stainless steel are iron, nickel, chromium, and manganese. The heavy metals in it will also dissolve in the water, and the deposition of heavy metals in the human body will cause lesions, and titanium containers do not have these problems. Take bamboo and wooden chopsticks as an example. The so-called illness comes from the mouth. After repeated use, the worn chopstick head will hide food residues. Over time, aflatoxin will be produced. Aflatoxin is classified as a class 1 carcinogen by the World Health Organization, and its toxicity is 10 times that of the highly toxic substance potassium cyanide and 68 times that of arsenic. And the health of titanium metal is non-toxic, and the natural bacteriostasis, can always care for the health of the family, which is hard to compare with ordinary metals.

Titanium household products have no dissolution of nickel, chromium, and manganese, which are pathogenic and carcinogenic metals, in high temperature, acidic or alkaline food environments, and have the characteristics of never rust, natural bacteriostasis, biophilicity, long-term freshness, durability, etc. It is welcomed by consumers, but its price is no less than that of high-end consumer goods. People can't help wondering what exactly makes the price of titanium household products so high? There are several reasons.

Expensive material cost

Due to the mature technology of some commonly used household goods, the cost has been controlled and optimized, and the price has been fully accepted by the market. For titanium metal, due to the high production cost and low material yield of titanium, the price of titanium sheets of the same size is more than 10 times that of stainless steel 201 or 304. Considering that the proportion of titanium is much lighter than that of stainless steel, the cost of the material used It is also 5 to 7 times higher.

困难 difficult to process

Titanium material itself is a typical difficult-to-machine material, which has extremely high requirements on equipment, molds, tools, tooling, and processing technology. But once processed, he can be said to be "unbreakable." The difficulties in processing titanium profiles are mainly manifested in the following aspects:

1. Cutting of titanium is difficult. The deformation coefficient of titanium alloy is less than or equal to 1, and the contact surface with the rake face during cutting is small, which makes the contact zone pressure and local temperature high, and the tool wears quickly. At the same time, titanium can cause severe work hardening during processing.

2. Titanium is difficult to weld. During welding, titanium in high temperature state easily reacts with hydrogen and oxygen in the air, causing "hydrogen embrittlement", which causes the product to easily crack and the yield is low.

3. Titanium is difficult to stretch. The tensile processing of titanium has high requirements on the material, specification tolerances and tensile properties of the titanium plate, and the requirements for the mold matching are higher, otherwise the product is easy to wrinkle or break. At the same time, the equipment travel speed and the lubricating oil used are also very particular. How to heat-treat the titanium material that has been stretched for many times is more difficult. These problems will directly reduce the yield.

4. The surface treatment of titanium is difficult. Because the "man, machine, material, method, and ring" of titanium polishing are different from the conventional materials, the processing cost of titanium surface treatment is several times or even more than ten times that of other materials.

High development cost

Because the relevant processing data of titanium civilian products is incomplete, the development cycle is longer, the mold needs to be repeatedly modified and debugged, and there may be scrap and unsuccessful development. For example, the normal cost of a set of molds for a pure titanium electric kettle is usually 3,400,000 yuan. Due to the limited order of pure titanium electric kettles, the production quantity is far less than that of stainless steel products, so the evenly distributed mold cost becomes particularly expensive .

High cost of new product promotion

Because authoritative academic institutions or mainstream media have very few related research and reports on titanium and titanium products, many end consumers know little about titanium as a material, and it is harder to know the practical benefits of using titanium household products.

Fortunately, thanks to the development and long-term unremitting promotion of domestic titanium processing companies and titanium brand companies in their respective fields, we have overcome one technical obstacle in titanium processing and opened one titanium product after another. In the market, there are more and more people who dare to be the first to eat crabs, more and more beautiful and practical titanium household products, and more and more well-known household enterprises are involved.

For the titanium used in processing, titanium industry associations, enterprises and individuals are working hard to formulate and implement relevant standards, so that titanium-related companies can rely on it and make consumers more confident. Titanium's drawing, welding and polishing processes are also being further improved and perfected, and some special processing equipment and accessories are also coming to market. For example: when drawing, the lubricant is selected well and the yield is higher; the advent of special welding equipment makes the titanium weld more perfect; new titanium polishing processes, equipment and auxiliary materials make the surface treatment of titanium easier. Various improvements and changes make the good titanium products better present to the public.

 The civilianization of titanium metal is a concrete manifestation of the improvement of people's quality of life. This is the starting point to understand another healthy life. In the process of developing and promoting titanium products, Zhongshan Heshun Titanium Industry did not rush to expand the market, but was more willing to refine and upgrade the product, find the product positioning, and make it a reputation. As the saying goes: Focus on things to go further. It is not that a higher-priced product can be called a "luxury" product. What can really accompany people and help people get healthy is the biggest luxury product.

Because of knowing the advantages of titanium household products, and feeling the development prospects of titanium household products, well-known companies that traditionally produce stainless steel, glass and plastic household products are also constantly involved, and they are actively trying to produce and promote titanium household products. There will be more people who know titanium, are familiar with it, and enjoy it. As the demand for titanium products rises, the various costs of titanium products will also decrease. I believe that in the near future, healthy titanium household products will become a household name, adding a solid guarantee for the happiness and healthy life of more people.
