Application of Titanium and Its Alloy in Marine Industry
Titanium alloys are widely used in the marine industry due to their excellent corrosion resistance, high specific strength and non-magn tic properties under marine conditions. At present, the parts that titanium has been applied to on ships are: pressure shell, propeller and paddle shaft, sea pipeline, valves and accessories, various pipe joints, heat exchangers, coolers, condensers, engines, parts , lifting device and launching device, acoustic device parts, mooring device, etc.
Titanium pressure vessels are mainly used in deep-sea submersibles and submarines. The United States, France, Japan, and China all use titanium pressure vessels to varying degrees: such as the US deep submersible equipped with titanium observation cabin and control cabin, the dive depth can reach 6100m; Japan uses Ti-6Al - 4V ELI alloy, the depth of dive reaches 6500m; China has also achieved certain results in deep submersible technology.
The cavitation corrosion resistance of titanium alloys is far superior to steel and copper-nickel alloys. Therefore, propellers and propeller shafts made of titanium can reduce cavitation corrosion speed, prolong service life and improve propulsion efficiency. Titanium alloy is resistant to high-speed seawater scouring, and it does not cause scouring corrosion even when used at a flow rate of 13 m/s. It is especially suitable for pipelines where the working medium is high pressure, high flow rate, and moving seawater. The use of titanium to make ship-to-sea pipelines and valves also reduces pipe diameter and the thickness of the pipe wall.
In ship engines, titanium alloys are mainly used to make engine discs and blades to substitute heat-resistant steel. With the development of titanium alloys on ships, titanium alloys are increasingly used for ship mooring ropes, anchoring devices, rescue buoys, signal buoys and masts. In addition, titanium alloys are also used to make various microphones, sonar flow guides, telephone parts, underwater acoustic transducer components, and the like.
Today we introduce the application of titanium alloy in marine industry. And of course, it is still one part of the many applications of titanium and its alloys.

Application of Titanium and Its Alloy in Chemical Industry
Hello everyone, it's been a while since we last met. Do you still remember what we have talked about in the last few weeks? Well, if you forget that, let me remind you that we kept talking about the applications of titanium and titanium alloy, including in aerospace, human implants and sports equipment. For more detailed information, please refer to What is the commercial value of titanium. And today, Magic Metal World is going to introduce its application in chemical industry.
As we all know, titanium has excellent corrosion resistance, mechanical properties and process properties and is widely used in many industries. In the chemical industry, titanium is used as a corrosion-resistant material to replace stainless steel, nickel-based alloys and other rare metals. This is of great significance in increasing production, improving product quality, extending equipment life, reducing consumption, reducing energy consumption, reducing costs, preventing pollution, improving working conditions and improving labor productivity.
Titanium has become one of the main anti-corrosion materials in chemical equipment, and has established his corrosion resistance status in chemical plants. As an ideal material in chemical equipment, titanium has also attracted more and more attention from engineers and technicians.
After years of promotion, titanium and its alloys have been widely used in chemical production as an excellent corrosion-resistant structural material. At present, the application of titanium equipment has expanded from the original soda ash and caustic soda industries to industries such as chlorate, ammonium chloride, urea, organic synthesis, dyes, inorganic salts, pesticides, synthetic fibers, fertilizers, and fine chemicals. The survey results show that titanium heat exchangers account for 57%, titanium anodes account for 20%, titanium containers account for 16%, and others account for 7%.
However, in the application of titanium alloy in chemical industry, the expensive price is a problem to be solved. For more information about reducing titanium alloy, please refer to How to reduce the price of titanium alloy. The above is the application of titanium and titanium alloys in the chemical industry. Guess what we want to talk about next time? See you soon.

Application of Titanium and Its Alloy in Sports Equipment
We know that titanium has huge commercial value in modern society. Titanium and its alloys have wide application in aerospace, marine, human implants and so on. In addition, titanium is also marching into the field of sports equipment.
The largest application area at present is that the world is using titanium to cast golf club heads. At the end of the 1980s, Japan began to develop titanium alloy cast golf heads (commonly known as wood) and achieved good results. Titanium is light in weight and high in strength. Compared with stainless steel, it can make a ball head with a larger impact surface and a larger volume, so it can be played far. What's more interesting is that when using a titanium alloy ball head, it will make a good sound when hitting the ball, which makes the athlete feel good. Therefore, the titanium alloy ball head has been greatly developed.
In recent years, high-strength titanium alloy (Ti-15-3 alloy) precision-cast ball head, newly developed precision-cast titanium ball head with tungsten alloy insert and new damped titanium alloy ball head have developed rapidly in sports equipment. Nowadays, the manufacture of titanium alloys for golf clubs has formed an industry with a certain scale of production. According to statistics, in the Japanese market, the number of golf heads sold in June was 60,000, and in 1995 it surged to 1.5 million, with annual sales reaching US$70 million. In 1996, the demand for golf club heads in the United States reached 1000 t to 2000 t. These figures are relatively old, and the figures in recent years are even more surprising.
In recent years, titanium alloys have been applied on bicycles, motor boats, softball bats, long hockey sticks, tennis rackets, harnesses, sprint spikes, mountaineering tools, snowboards, wetsuits, roller skates, fishing tackles, and competitive wheelchairs. At present, titanium and its alloys are most widely used in the aviation industry, and their application in sports equipment is 1/3 of aviation. Anyway, titanium has great potential in sports equipment.

Application of Titanium and Its Alloys in Aerospace
The metal element titanium is widely distributed in the earth's crust, and its content is about 0.4% of the crustal mass. The world reserve of titanium is about 3.4 billion tons and ranks 10th among all elements (oxygen, silicon, aluminum, iron, calcium, sodium, potassium, magnesium, hydrogen, titanium). Its abundant reserve provides a major source of raw materials for the production and development of titanium and titanium alloys. Since the 1950s, the types of titanium alloys have evolved from the 1954 Ti-6Al-4V alloy to the current hundreds of alloy types.
Titanium alloys are widely used in various fields, including aerospace, automobile manufacturing, medical and health, and other fields of daily life because of their high strength, good corrosion resistance, and high heat resistance. Thus, Magic Metal World decides to start a column introducing different applications of titanium and its alloys, please follow us for subseuent updates. Today we will first discuss the application of titanium and its alloys in aerospace.
Since the 1950s, titanium alloys have developed rapidly in the aerospace industry. This application mainly utilizes the excellent comprehensive mechanical properties, low density and good corrosion resistance of titanium alloys, because the materials of aerospace frames require high tensile strength, good fatigue strength and fracture toughness. The excellent high temperature tensile strength, creep strength and high temperature stability of titanium alloys have also made them suitable for use in jet engines.
Titanium alloy is one of the main structural materials for modern aircraft and engines. It can reduce the weight of the aircraft and improve the structural efficiency. The spacecraft's payload is relatively small compared to the aircraft, so the weight loss of its structure is even more important. Titanium alloys have been used in the earliest Apollo and Mercury programs, and fuel tanks and satellite pods are typical applications for titanium alloys. Titanium alloys are more advantageous than high-strength steels because of their light weight, high strength and long-term chemical stability with fuel. For example, Ti-3Al-2.5V alloy was developed for low temperature applications and still has good toughness and plasticity under cryogenic conditions in space.
Today we only briefly introduce the application of titanium and its alloys in the aerospace industry. Please pay attention to our website for more information.
