Product Description

TiAl is a new class of aerospace alloys that offers an excellent strength-to-weight ratio as well as high chemical and thermal stability. Gamma titanium aluminide alloy has excellent mechanical properties as well as oxidation and corrosion resistance at elevated temperatures (over 600 degrees Celsius). TiAl is the latest class of materials competing with Nickel superalloys for the fabrication of aircraft engine parts such as low-pressure turbine.

Titanium alloy powder are prepared by high-purity argon atomization and plasma rotating electrode atomization processes. The products include titanium alloys, Ti-Al alloys, Ti2AlNb, Ti-Ta alloys, Ti-Nb(-Zr) alloys, niobium alloys , tantalum alloy, etc. The powder has low oxygen content, high sphericity, good fluidity and stable performance, which can well meet the different needs of electron beam powder coating 3D printing, laser powder coating 3D printing, laser coaxial powder feeding 3D printing and other processes.

Applications

How we play a role in the industry

VIEW ALL APPLICATION
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.
