Pedal Titanium Axle Titanium is light. Commonly used in aviation

Titanium and stainless steel plate What is the difference
If it is just made of titanium titanium plate description of a chemical composition of elements.
Stainless steel much cheaper. Uses titanium rod more extensive. Why not rust stainless steel, adding more than about 12.5% ​​chromium steel in. Corruption and incompetence in the oxidative corrosion medium, chromium can
The steel surface quickly generate a dense layer of passivation film to prevent metal matrix is ​​destroyed. When the chromium content of 12.5% ​​in the above form a dense layer of stable passivation film, rust resistance
The real change occurred leap forward, the ability to greatly enhance corrosion resistance, which is why more than 12% of the reason for the amount of chromium-containing stainless steels have.
Commonly used stainless steel 304 chemical elements of which one seemed to 1Cr18Ni9Ti refers to the carbon content. Cr18 means that the content of titanium rod for sale chromium. Ni9 refers to the nickel content is what you said above Ti titanium plate in
Titanium it.

Titanium is light. Commonly used in aviation. Medicine. And corrosion-resistant. So the value is more expensive.

Pedal Titanium Axle Titanium and aluminum are essentially different

Difference titanium, aluminum
   Titanium and aluminum are essentially different , but sometimes they are just like some of the products , Pedal Titanium Axle it is not difficult to identify them carefully observed , particularly titanium magnesium alloy doors and aluminum doors , details about the specific distinction below :
    1, the titanium added to the titanium- based alloy other alloying elements called titanium . Titanium has a low density , high strength , corrosion resistance , good process performance , etc., is an ideal aerospace engineering structural materials. Titanium and titanium alloy structure can be divided into heat titanium, titanium alloy , or α , β , and α + β type titanium alloy titanium alloy . Study also include forming technology of titanium alloys , powder metallurgy technology, rapid solidification technology , titanium military and civilian fields.
    2 , aluminum is aluminum titanium standard parts made ​​by adding some alloying elements such as aluminum - manganese alloys, aluminum - copper alloys, aluminum - copper - magnesium-based hard alloy, Al - Zn - Mg - Cu based hard alloys. Aluminum has a better than aluminum physical and mechanical properties : easy processing , high durability , wide application , good decorative effect , rich color . Rust-proof aluminum into aluminum, hard aluminum , hard aluminum and other types of various types have their own range , and have their own code , in order for users to choose.
    3 , remains a lightweight aluminum features, but significantly improved mechanical properties . titanium industrial bar Application of aluminum alloy has the following three aspects : First, as the force components ; Second, as doors, windows , pipes, covers, shells and other materials ; Third, as a decorative and insulating material . After the use of aluminum anodized characteristics can be colored , made of various decorations. Aluminum alloy sheet, the surface profile can be corrosion, ginning , painting, printing and other secondary processing to produce a variety of decorative plates, profiles, as a decorative material.

titanium round bar When the possibility of titanium welding

Titanium tube weld cracks and pores problems
Titanium tube weld crack problem
When the possibility of titanium welding, titanium round bar thermal cracking of welded joints is small, it is because few impurities in titanium and titanium alloys S, P, C , etc. , low melting point of S, P eutectic formed at the grain boundaries rarely generation, coupled with effective crystallization temperature range narrow, titanium and titanium alloy solidification when a small amount of shrinkage , weld metal does not produce heat cracks.
When titanium and titanium alloy welding, weld when an oxygen , nitrogen is high , the performance of the weld heat affected zone or become brittle in the larger weld stress, cold cracking occurs . Characterized by cracks in the weld called a few hours or even longer delay cracks. The study showed that the hydrogen diffusion welding process is the main cause of such cracks. Hydrogen in the welding process to a lower temperature by diffusion of the high temperature heat affected zone deep pool , the area increase the hydrogen content of the precipitates increased so that the amount of TiH2 , brittle heat affected zone is increased , the other due to volume expansion caused by precipitation of hydrides greater the stress , plus a hydrogen atom diffusion and aggregation to the high stress areas of the area, resulting in the formation of cracks . This delay prevents cracks approach is titanium industrial bar to reduce the welded joint main source of hydrogen .
Titanium tube weld porosity problems
When titanium pipe welding , porosity is often encountered a major problem. The root cause of the formation of pores is affected as a result of hydrogen .
Prevent blowholes process measures are:
1 ) in high purity argon welding , argon gas purity not less than 99.99%
2 ) the elimination of titanium tubes , oil and other oxide on the surface of titanium and titanium tubes eye organics . Can be cleaned with a chemical and mechanical methods.
3 ) subjected to the bath gas well , control the flow and the flow rate of argon gas , to prevent turbulence , impact protection.
4 ) Choose the appropriate welding process parameters, welding specification , increasing the residence titanium bar supplier time of deep pools to facilitate the use of air bubbles escape , which can effectively reduce porosity.

titanium bar stock Memory alloy pipe has been used in combination

Memory alloy pipe has been used in combination with automatic control , the sleeve may be made ​​of shape memory alloy instead of welding , is in the low temperature expansion of the tube to approximately 4% of the full , a socket assembly with a heated , titanium bar stock shrinkage of the sleeve restore the prototype , form a tight engagement . U.S. Navy aircraft hydraulic system uses a 100,000 such joints, oil spills and damage over the years never happened . Ship and submarine oil pipeline damage , repair it with a shape memory alloy fittings, very convenient. In some parts of the inconvenience of construction , the pin made ​​of shape memory alloy , into the hole is heated to separate the trailing end automatically curl to form single assembly .
Memory alloy is particularly suitable for thermo-mechanical and automatic temperature control , automatic opening and closing has made ​​room arm can open the windows are in the sunshine during the day , automatically turns off when the night temperature drops. Memory alloy heat engine designs are also a lot that they can be in with a low temperature difference between the two media work , so as to take advantage of industrial cooling water , nuclear reactor heat, ocean thermal and solar power opened up titanium round bar new avenues . Now the problem is widespread efficiency is not high, only 4 % to 6% , to be further improved .
Memory alloys in medical applications is also very compelling. E.g., the bone with the bone plate , not only can two fixing broken bones , and the recovery of the original shape of the compression force is generated , forcing the broken bones are joined together . After straightening teeth using dental wire , long clip ligation of cerebral aneurysms and vas deferens , with the support plate straightening the spine , are implanted in the human body temperature by the action starts, thrombus filter is also a new product memory alloy . After being straightened filter implanted vein , will be gradually restored into a network , thereby preventing clot 95% flow to the heart and lungs.
Artificial heart is a more complex titanium industrial bar structure of the organ , muscle fibers of the elastic memory alloy thin film made ​​of ventricular cooperate to mimic ventricular contraction . Now water is pumped been successful.
