Titanium alloy rod corrosion resistance GR5 titanium rod high strength

Titanium metal has great passivation property, in many cases, when contacting with dissimilar metal, it does not accelerate the corrosion, but may accelerate the corrosion of dissimilar metal.  For example, in low concentration of non-oxidizing acid, if Pb, Sn, Cu or Monel alloy contact with titanium to form galvanic pair, the corrosion of these materials is accelerated, and titanium is not affected.  Corrosion resistance, high strength, acid and alkali resistance, light weight, etc.  

Titanium alloys are alloys based on titanium with other elements added.  Titanium has two kinds of homogeneity crystal: titanium isomer, melting point is 1668℃, below 882℃ is a dense hexagonal lattice structure, called α -titanium;  Above 882℃, the cubic structure is called β -titanium.  Titanium alloys with different structures can be obtained by adding appropriate alloying elements and changing phase transition temperature and component content.  

Physical phenomenon of titanium processing: the cutting force of titanium alloy processing is only slightly higher than that of steel with the same hardness, but the physical phenomenon of titanium alloy processing is much more complex than that of steel, so that titanium alloy processing is faced with great difficulties.  Most titanium alloys have very low thermal conductivities, only 1/7 of steel and 1/16 of aluminum.  Therefore, in the process of cutting of titanium alloy heat will not quickly passed to the artifact or taken away by chip, and agglomeration in cutting area, the temperature can be as high as 1 000 ℃ above, make the cutter blade quickly wear, cracks, and generate the devolop tumor, rapid wear of the blade, and make the cutting area produces more heat and further shrinkage of life.  The high temperature in the cutting process destroys the surface integrity of titanium alloy parts, resulting in the decrease of geometric accuracy and the phenomenon of work hardening which reduces the fatigue strength seriously.
