Performance Titanium

Medical titanium supplier is a new titanium metal, titanium and carbon contained in the performance, nitrogen, hydrogen , oxygen, etc. related impurities, the most pure titanium iodide impurities is not more than 0.1%, but lower titanium alloy plate strength, high ductility. 99.5% for the performance of industrial pure titanium: density ρ = 4.5g / cm3, a melting point of 1800 ℃, thermal conductivity λ = 15.24W / (mK), tensile strength σb = 539MPa, elongation δ = 25%, necking rate ψ = 25%, the elastic modulus E = 1.078 × 105MPa, the hardness HB195.

 Density medical titanium plate titanium alloys generally about 4.5g / cm3, only 60% of steel , close to the strength of ordinary strength titanium steel, some high-strength titanium alloy over the strength of the many structural steel. Therefore, the ratio of titanium alloy strength (strength / density) is much larger than other metallic structural materials, the unit can be made of high strength, rigidity, lightweight parts and components. Currently aircraft engine components, skeleton, skin, so the use of titanium fasteners and landing gear.

Alloying elements according to their impact on the phase transition temperature can be divided into three categories

① stable α phase, phase transformation element is α stabilizing element, aluminum, carbon, oxygen and nitrogen. Wherein the aluminum alloy is the main alloying elements, and its improved high-temperature strength of the alloy at room temperature, reduce the proportion, significantly increase effective elastic modulus

② stable β phase, the phase transition temperature of the lower element of β stabilizing element, can be divided into the same crystal type and eutectoid two. Application of titanium alloy plate products
The former molybdenum, niobium, vanadium; the latter are chromium, manganese, copper, iron, and silicon.
③ small element of the phase transition temperature of the neutral element, zirconium and tin.
Oxygen, nitrogen, carbon and hydrogen are the main impurities of titanium. Oxygen and nitrogen in the α phase has a greater solubility of medical titanium plate  significant strengthening effect but the plastic drop. Usually it provides the titanium content of oxygen and nitrogen in the 0.15 to 0.2% and 0.04% to 0.05% or less, respectively. The solubility of hydrogen in the α phase is very small, titanium dissolved hydrogen will produce excess hydride, the alloy becomes brittle. Titanium usually hydrogen content control 0.015%. Hydrogen was dissolved in titanium is reversible, can be removed by vacuum annealing.

Titanium plate having stable chemical properties and excellent biocompatibility

Titanium alloy plate Extremely hard, lightweight, can resist erosion. In general, mainly for engineering and aviation industries. Titanium is also used in jewelry and only recently its popularity index is on the rise.

Titanium whole distributor Also known as space metal, having the characteristics of the future, hard and tough, corrosion-resistant, bright silver, not black, not allergic to any person, it is the only no effect on the human autonomic metals. Its unique high polished silver tone whether, silk, matt has a very good performance, in addition to gold, silver jewelry the most suitable material, commonly known as titanium market.
Medical titanium plate widely used in the medical field, titanium has stable chemical properties and excellent biocompatibility, in the human body, can resist the corrosive and non-toxic secretions, adapts to any sterilization method. Titanium products because the hotel has a corrosion resistance, high stability, in substance and when it touches, no chemical reaction.
