Titanium alloy plate prices

Titanium alloy plate at the current price trend is not particularly good, the recent domestic titanium plate market demand are relatively sluggish, prices remain low stage, the short term, the market price will be difficult to recover, the current 2mm pure titanium plate price in the 105-115 yuan / kg (15.51-16.99 dollars / kg). Titanium is a metallic titanium coil element, grey, atomic number 22, relative atomic mass 47.87. Combustion in nitrogen, high melting point. Blunt titanium and titanium based alloy is a structure with new materials, mainly for the aerospace industry and marine industry.
Titanium density of 4.506-4.516 g / cubic centimeters (20 DEG C), higher than that of aluminum and iron, copper, nickel below. But in the first than the strength of the metal, is 3 times of stainless steel, is the aluminum alloy [colored business: 1.3 times of the aluminum alloy plate]. The melting point of 1668 - 4 DEG C, the latent heat of fusion of 3.7-5.0 kcal / atom, the boiling point of 3260 plus or minus 20 DEG C, the latent heat of vaporization of 102.5-112.5 kcal / atom, the critical Aerospace titanium castings temperature of 4350 DEG C, the critical pressure of 1130 atm. Poor thermal conductivity and conductive properties of titanium, similar to or slightly lower than stainless steel, titanium superconductor, superconducting critical temperature of pure titanium 0.38-0.4K. At 25 DEG C, titanium heat capacity is 0.126 cards / atom and degree, 1149 card / molecular enthalpy, entropy is 7.33 cards / atom and degree, metal titanium is paramagnetic material, permeability is 1.00004. Titanium has plasticity, extending high pure titanium rate can reach 50-60%, section shrinkage rate of 70-80%, but low strength, not as structure material. Titanium in the presence of impurities, a great influence on the mechanical properties, especially the interstitial impurities (oxygen, nitrogen, carbon) can greatly improve the strength of titanium, significantly reduced its plastic. Good mechanical properties with titanium as a structural material, through strict control of the impurity content is appropriate and adding alloy elements and to achieve.
