Tungsten alloy Marine counterweight for yacht, sailing, submarine, such as
the provision to resist lateral force components in sailing. Boat in the water
weight is not enough, easy to turnover, especially in high winds. When sailing
ships carrying goods, to the specific port, the goods will be unloaded. To keep
the ship upright, it is necessary to put some weight of high specific gravity
and things to do. In large modern ships, keel is often with a high proportion of
materials or containing such materials, such as lead. But tungsten boat pollution caused
by lead, so due to the high proportion of tungsten materials and non-toxic, it
has been more and more used in the ship weight. Place the counterweight to the
lower (usually at the bottom of the keel) is to maintain the balance of the
ship.
an alloy containing a certain amount of the element α stable α phase equilibrium composition mainly composed of α-phase. α alloy proportion of small, good heat resistance, good weldability and excellent corrosion resistance, the disadvantage is the low temperature strength, and corrosion resistant material commonly used as the material.

Titanium and titanium standard surface shading techniques
Coloring treatment of titanium and titanium alloys : titanium and titanium alloy surface is silver , with excellent corrosion resistance , titanium if you want to perform a variety of shading . About three Xinnuo titanium alloys coloring method in three ways: atmospheric oxidation, anodic oxidation, chemical treatment . Now the most commonly used is the anodic oxidation. We will be a test to intuitively understand the anodic oxidation. First, now with the solution. The aqueous solution was distilled with sulfuric acid, the sulfuric acid concentration is low , less than 1:10. Begin to make experiments with waste titanium products , titanium alloy anode , cathode with a thick copper wire when , put together the above electrolyte. Through the power after the bubble began to take . OK OK after the beginning of shading , coloring into the aqueous solution of titanium rod stock needs .

Titanium and titanium standard welding technology
At present, many metal products are used in place of
Xinnuo titanium and titanium alloys , but during welding repair , still rely on laser equipment , because the
titanium alloy sheet material strength and corrosion resistance is higher than other materials , but instead of the technology in other industries , particularly high-tech technical
titanium alloys , such as : external structure engines, parts and other products , not only reduces the weight of the product itself , but also to improve the quality and safety of the machine , in order to fully applied in the production process, often with a variety of facilities needed
Titanium and titanium standard
The main raw material used to produce titanium titanium dioxide ( titania ) , titanium ( titanium sponge ) , titanium steel and welding rod coatings. Their proportion slightly different country and abroad . Titanium , China accounted for 88 percent , accounting for 92.4% abroad ; metallic Xinnuo titanium industrial bar ( titanium sponge ) , China accounted for 10% , and 5.3% abroad ; containing titanium steel and welding rod coatings, China accounted for 2.0% , 2.3% abroad . Titanium is not only excellent performance of white pigment , and is an important chemical raw materials. It is widely used in coatings, inks, plastics , rubber , paper and chemical industries. Titanium dioxide paint , colorful , color pure ; Titanium is a senior filler paper to make paper thin and opaque whiteness , gloss , strength and smooth to use. Titanium dioxide used in the plastics industry , is opaque colorants ; for the rubber industry , so white and light-colored rubber high strength, elongation , resistance to aging and will not fade. It is also the best extinction chemical fiber materials , so that a permanent and transparent fiber matting effect , and improve toughness. In addition, for aspects enamel , electrical appliances, electronic materials , and so on . Titanium ore was smelted into titanium sponge , then ingot made ??of commercially pure titanium and titanium alloys and titanium metal . Titanium and titanium alloy titanium is mainly used in aviation and aerospace sectors. Compared with steel, titanium aircraft can reduce the weight by 40%. Others such as satellite shell, skin spacecraft , rocket motor case , missiles , etc. ,
Marine titanium standard welding process
Shipbuilding in thickness of 4mm Ti70 and 16 mm for welding object, plasma arc welding , laser welding and laser - arc hybrid welding Xinnuo titanium alloys welding three high energy density of the process carried out explore, get a good performance of welded joints , plasma arc welding , plasma arc welding is the use of plasma arc welding process as a heat source . Gas heated by the arc generated from the solution , a nozzle at high speed compressed by water , and increasing the energy density of the solution from forming a plasma arc. Its stability , heat and temperature are higher than the arc , and thus has a greater penetration power and welding speed . For marine titanium bar price welding tests show that plasma arc with concentrated energy , penetration , side welding good shape , no tungsten inclusions , less porosity , etc. , it is very suitable for welding of titanium and titanium alloys . More plasma arc welding process parameters , when the method is mainly related to the use of orifice nozzle diameter , welding current, plasma gas flow rate , welding speed , shielding gas flow. Second, the heat of the laser welding is a welding laser beam is focused as a laser weldment bombardment energy generated as a welding method for welding high precision . Laser welding due to the high energy density, obtained greater penetration and high welding speed , and because the diameter of the laser beam is extremely small, so narrow weld and heat -affected zone , the welding residual stress and deformation is small . The main parameters of laser welding laser welding power , welding speed , titanium bars for sale amount , side-blown gas flow and shielding gas flow. Since the laser welding high welding speed , the welding process generally can not adjust the parameters of the process ,

What is the use of titanium standard
First, the advantages of titanium rod is more, not only high strength, low density , and good mechanical function , tolerance and corrosion resistance is also very good . So what are titanium rods used for? Let Xiaobian to tell you about .
Titanium industrialized production beginning in 1948 . Carried out by the aviation industry needs to make the Xinnuo titanium wire manufacturers industry with about 8% of the average annual growth rate of conduct . The current international titanium alloy production reached 40,000 tons , nearly 30 kinds of titanium trademark . Is the most widely used welded titanium tube alloy Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) and commercially pure titanium (TA1, TA2 and TA3). Titanium is mainly used for the production of aircraft engine compressor components , followed by rockets, missiles and high speed aircraft structural parts . Mid-1960s , titanium tubing and its alloys have been in use in the industry generally , the electrodes used in the production of electrolytic industry , power plant condensers, heater oil essence and desalination and environmental pollution control equipment. Titanium and its alloys have become a corrosion layout information .
In addition, for the production of hydrogen storage materials and shape memory alloys. Titanium is the aerospace industry in the use of an important new layout data , the proportion between the strength and the use of aluminum and steel temperature range , but high strength and excellent corrosion resistance to sea water features and ultra-low temperature capabilities. The amount of titanium in the aerospace engines typically 20% to 30% of the total weight of the layout , mainly for the production of compressor parts, such as casting titanium fan , compressor discs and blades, cast titanium target compressor casing , intermediate casing, bearing housing and so on. The primary use of titanium spacecraft high specific strength , corrosion resistance and low temperature capabilities to produce a variety of pressure vessels, fuel tanks , fasteners, instrument straps, architecture and rocket shells. Sputnik , the lunar module , manned spaceship and space shuttles are also using titanium plates welded parts .
