Ti811 Titanium Alloy Powder
Ti811 (Ti 8-1-1) is a near alpha alloy with superior creep resistance. TRUER ® Ti 8-1-1 can provide creep resistance at operating temperatures up to 455°C and is used primarily in engine applications such as forged compressor blades and disks. This alloy has a relatively high tensile modulus to density ratio compared to most other commercial titanium alloys. Good weldability is another advantage of Ti811 alloy.

TRUER ® Ti 8-1-1 can provide creep resistance at operating temperatures up to 455°C and is used primarily in engine applications such as forged compressor blades and disks. This alloy has a relatively high tensile modulus to density ratio compared to most other commercial titanium alloys. Good weldability is another advantage of Ti811 alloy.
TRUER® Ti 811 spherical powder (Ti-8Al-1Mo-1V) is prepared by the plasma rotary electrode atomization process (PREP) or Electrode induction gas atomization (EIGA).
Its common particle size range of Ti811 powders includes 15-45um, 15-53um, 20-63um, 45-106um, 53-150um which can be applicable in AM, including SLM, EBM, DED etc.

Applications
How we play a role in the industry
HIP Technology
Hot Isostatic Pressing (HIP) technology works by placing the product in a closed container, filling it with inert gas and sintering or densifying the product at a very high temperature (usually close to the forging temperature of the material) and at a very high pressure (usually 100 – 140 MPa). This allows the product to be sintered or densified.
MIM Technology
MIM products can be complex in shape, precise in size, high in strength and produced automatically in large quantities, and can significantly reduce the complexity and cost of traditional metalworking
SLM Technology
SLM, also known as Selective Laser Melting, is similar in principle to SLS in that a laser is used to melt and solidify metal powder in a specified area, which is then moulded in a layer-by-layer stack.
EBM Technology
Electron beam melting refers to a vacuum melting method in which the kinetic energy of a high speed electron beam stream is converted to heat as a heat source for melting metals under high vacuum. The abbreviation is EBM.
