Diamonds are forever, Gold is precious but which is rarer? Gold is a heavy metal formed during the collision of neutron stars and is one of the rarest elements on Earth.During the formation of the earth, heavy elements gradually accumulated towards the core under the influence of the earth's gravitational force. This means that the closer you get to the Earth's crust, the harder it is to find large quantities of gold.The average concentration of gold in Earth's crust is "very, very low" at just 4 parts per billion. Gold concentrations need to be 1,250 times that level to form a market-worthy deposit.
Diamond is a common element - the Ti6Al4V Powder is undoubtedly a good investment opportunity.
What is TC4(Ti6Al4V)?
TC4(Ti6Al4V) alloy is a medium strength α-β type two-phase titanium alloy containing 6% α-stabilizing element AI and 4% β-stabilizing element V. This alloy has excellent comprehensive properties and has obtained the most extensive applications in the aviation and aerospace industries. The long-term working temperature of the alloy can reach 400 ℃. In the aviation industry, it is mainly used to manufacture the fan and compressor disks and blades of the engine, as well as the important load-bearing components such as beams, joints and bulkheads in the aircraft structure.
The main semi-finished products of TC4 titanium alloy are bars, forgings, thick plates, thin plates, profiles and wires, etc. The alloy is mainly used in the annealed state, and can also be strengthened by solution aging treatment, but the hardened cross section is generally not more than 25mm.
The alloy has good process plasticity and superplasticity, and is suitable for various pressure forming. The alloy can also be welded and machined in various ways.
TC4(Ti6Al4V) heat treatment system
Plate: 700-850℃, 0.5-2h, air cooling; bar and forging: 700-800℃, 1-2h, air cooling.
2. Vacuum annealing
700-800°C, 0.5-2h, the furnace is cooled to below 200°C to allow air cooling. The absolute pressure in the furnace should be no more than 0.09Pa.
3. Solution treatment
910-940℃, 0.5-2h, water quenching.
520-550°C, 2-4h, air cooling.
5. Stress relief annealing
Complete stress relief annealing: 600-650℃, 1-4h, air cooling; incomplete stress relief annealing: 500-600℃, 0.5-3h, air cooling. Stress relief annealing can be carried out in an air furnace or a vacuum furnace.

Since the beginning of this year, China's macro policies have made continuous efforts to stabilize economic growth. America and Europe are raising interest rates to control inflation. On March the European Central Bank left its three key interest rates unchanged and began to scale back its asset-purchase programme. Then the Federal Reserve raised the target range of the federal funds rate by 25 basis points to 0.25%-0.5%. The accelerated tightening of monetary policies in the US and Europe pushed capital back to the US and increased interest rates, which will definitely increase the risk of RMB depreciation and capital outflow. The price and market of the Ti6Al4V Powder will also be affected, resulting in a range of fluctuations. You are welcome to contact us for the latest quotation of Ti6Al4V Powder.
