The hardness of pure titanium plate is several times that of ordinary steel plate.
The hardness of pure titanium plate is half that of ordinary steel plate.

According to the first chapter of the Handbook of Practical Metal Materials (second edition) edited by Liu Shengxin:

The hardness of industrial pure titanium is usually less than 120-290 Brinell hardness. The higher the purity, the closer the Brinell hardness is to 120 Brinell hardness.

Generally, the hardness of steel plate is: q235b, Brinell hardness (HBS 100/3000) (high temperature annealing or tempering): ≤2 17.

Ultrapure titanium

2065438+September 2004, the first furnace of China "Electronic-grade Ultra-low Oxygen Ultra-high Purity Titanium" was successfully developed and put into production in Yuyao City, Zhejiang Province, breaking the foreign monopoly in one fell swoop. Ultra-high purity titanium with low oxygen content is mainly used as sputtering target in core industries such as semiconductor, aerospace and offshore oil. , has important strategic significance. It is particularly worth mentioning that ultra-high purity titanium is an important raw material guarantee for China's independent large aircraft project.

Prior to this, the price of ultra-high purity titanium imported from abroad was about 6.5438+0.2 million yuan/ton, which was limited by purification technology. Only three companies in the United States and Japan can produce ultra-high purity titanium. As high-end Japanese materials, the US and strategic metals governments strictly restrict the export to China. China often depends on the "face" of the United States and Japan in the field of ultra-high purity titanium.

The commissioning of Ningbo Chuangrun New Materials Co., Ltd.' s "Project with an annual output of 250 tons of electronic grade low-oxygen ultra-high purity titanium" has filled the technical gap of high-end titanium materials in China, which means that China has the independent production capacity of low-oxygen ultra-high purity titanium, realized strategic metals's independent self-sufficiency and completely got rid of its dependence on foreign countries. After the monopoly is broken, the direct benefit is the aerospace field.
