titanium sheet How to distinguish a titanium frame

Titanium material found

Development of titanium materials: a German chemist in 1794 ( two hundred and seven years ago ) discovered this new metal element and named it titanium titanium. Named by sources from the ancient myth of the West Prince Titan ( Titan ) , because he titanium bar for sale believes that super-strength titanium and ultra- refractory degree , working with the great Titan with shine .

Although titanium material in the Second ○ was discovered seven years ago , but due to refining process was not easy ( titanium is very easy to combine with oxygen ) , scientists have been unable to be refined into useful substances metals. Until 1938 , DuPont developed a new way to extract , plus magnesium reduction method, the red and gold reserves in the ground ore , after chlorination, plus magnesium , restore it and become a sponge titanium, to a ninety-four three years , DuPont began producing a large number of titanium metal products.

Development of titanium frames

Titanium is a metallic chemical element , because the refining process is not easy, and less expensive titanium material production , it is only used in the early titanium aerospace science , marine science and other high-tech science and energy development . And daily necessities are to begin in 1965 applied to the titanium material .

The first titanium frame is in九八○年someone invented the " rivet -like titanium frames " titanium welding is a very difficult material, there is no better way to do early connection handling , use rivets type of way to put it nailed together. While in 1981 , the plant began buy titanium sheet outside coated with a layer of nickel titanium material to facilitate welding. An increasingly competitive market and month of the new manufacturing methods , 1982 Day MARUMAM company pioneered the first payment in full titanium metal frames around the world ; 1984 also has factories launched nickel-plated titanium frames , there is a big price difference .

Material development of titanium

1 . Full titanium : Frame in addition to the screws and plastic gloves for outside , all metal parts made ​​of titanium material .

2 . Nickel titanium package : Borders titanium material, the surface material using a nickel package , and now this frame no longer exists.

3 . Assembled Titanium: Due to the high cost of production of nickel and titanium package to update the device , it is not updated before , assembled titanium frames as the situation , but this product is dangerous because each metal has a different melting point, literally Putting it together will be very fragile. Early nickel- titanium frame package passes flattened angle , it 's not like a factory original border distribution of production so mean , so after use , nickel, and titanium -coated layer that will break out and no way to weld repair , titanium also includes assembling such a situation .

4 . Nickel-plated titanium : In order to reduce costs, make it easier on the production, but also come up with a factory nickel plated titanium . So then processed using conventional welding techniques .

How to distinguish between pure titanium frame

1 Check the weight.

2 Check magnetic reflection.

3 Check the hinge structure .

4 with a chemical reagent checked.

5 Test conductive index .

We can be a magnet placed on the table , then leaned over the frame , if it is not generating the magnetic response of titanium frames . Also check its hinge , titanium glasses are placed two plastic or metal liner in the hinge , in addition , because of different titanium round bar metals with different electrical conductivity , so with conductive index can be measured whether the titanium metal.

Now consumers in addition to care about aesthetics , but also pay great attention to security , such as European countries have regulations, things come into contact with human skin items ( such as glasses , watches , necklaces , etc. ) , if necessary ingredient containing nickel marked . Because the nickel whites sometimes cause skin lesions or skin cancer , so manufacturers and stores have a duty to inform .

medical titanium bar Such a process can greatly increase the strength

After an anti- aircraft J20 appear different from the past , the whole body almost see the rivets, some people said it was because the stealth coating covers the outside , so you do not see the rivets , in fact, this is wrong. F22 is using rivets , close look carefully medical titanium bar you can see it. Why not F22 rivets completely covered with a coating to see it? This is because the skin is F22 by a piece of riveting rivets up, rivets can not cover for easy maintenance , in case you can quickly remove the rivets skin pulls off a piece , and can determine with the naked eye whether the fuselage skin cracks.
    So J20 Why not see rivets it? In fact, this and related processing technology , due to the advances in technology, a large piece of titanium alloy ingots J20 using whole body casting , extrusion and then press through a dedicated , increased density , ( the two years prior to the successful development of the machine , once media have reported that this is the aircraft fuselage presses developed specifically for J20 ) , and finally the use of CNC machine tools hollowed out , which is a ** , high-precision CNC machine tools , the entire titanium aluminum alloy castings ( diameter may up to 3 meters ) hollowed out into the shape of the aircraft fuselage , so the aircraft do not need to cover the skin, the skin of the fuselage frame and a titanium alloy ingots are then processed , so do not see J20 rivets.

    After processing J20 in the fuselage just put on the surface of the fuselage stealth patch, we note the following diagram , J20 stealth patch is pasted a block , a bit like a submarine acoustic rubber blocks. If you later off a piece of stealth patch just paste a new on OK, so the aircraft maintenance is very easy .
    J20 of the integral processing technology is currently the world's first application in aircraft , F35 will still rely on the rivet , not to mention the Russian T50 , 20 years ago, the process is completely , there is no fundamental and J20 comparable. So an advanced aircraft can not just look at the surface , J20 to strategic needs medical titanium bar ( to carry large amounts of fuel to increase range and large anti-ship missiles ) and designed long body, such a body if the old conventional processing technology we rely the naked eye does not feel his body proportions , the body is too long , the body is weak at the middle of stress , where the most easily broken, but after the introduction of new technology completely eliminates this drawback . So just come out when J20 foreign aircraft design experts feel incomprehensible , but once the solution to doubt its processing will become clear.

medical titanium bar Titanium tube welded using inert gas welding area

Titanium tube welders law process characteristics
Titanium tube welded using inert gas welding area for the effective protection of TiG welding process. Since titanium has special physical and chemical properties , and thus there is a big titanium alloy wire  difference in the welding process and other metals.
