Product catalog summary

Overview
ALD Vacuum Technologies specializes in high-tech solutions for metal additive manufacturing, focusing on vacuum induction-melting inert gas atomization (VIGA) and electrode induction-melting inert gas atomization (EIGA) processes. These technologies are pivotal in producing high-quality metal powders for various industries, including superalloys and dental alloys.

VIGA Process
The VIGA process is renowned for producing superclean, spherical powders with high tap density, suitable for superalloys like Inconel 718 and CoCr. It supports plant sizes ranging from 20 to 2000 tons annually, ensuring repeatable product quality and consistent particle size distribution.

EIGA Process
EIGA is ideal for refractory and reactive alloys such as CP-Ti and TiAl6V4. It offers a robust, repeatable process without the need for a refractory consumable crucible, producing superclean powders with high tap density.

Technical Specifications

Equipment Dimensions: VIGA equipment height ranges from 9-16 meters, while EIGA ranges from 7-10 meters.
Power Requirements: VIGA requires 80-1500 kVA, and EIGA requires 80-300 kVA.
Vacuum and Leak Rate: Both processes operate at an ultimate vacuum of 5 Pa with a leak rate of 5 Pa l/s.
Production Capacity: VIGA can produce 50-2000 MT annually, whereas EIGA can produce 50-250 MT.
Gas Specifications: VIGA uses N2 or Ar at 20-60 bar, while EIGA uses Ar or N2 at 15-35 bar.

Powder Characteristics

Alloys: VIGA is suitable for CoCrMo(W), In625, In718, In738, while EIGA is suitable for CP-Ti, TiAl6V4, TiAl, Zr702, and precious metals.
Particle Morphology: Both processes produce spherical powders.
Particle Size Distribution: VIGA offers a d50 range of 35-70 μm, and EIGA offers 60-100 μm.

Company Information
ALD Vacuum Technologies GmbH is based in Hanau, Germany, with a global sales and service network. They offer testing facilities for powder production in Germany.
