Products
Gas-Atomized Aluminium and AlSi10Mg Powder
In gas atomization, nitrogen, argon or helium is used as the protective atmosphere and as the atomizing gas. The powders produced are regularly spherical and contain no porosity. When production parameters are well optimized, the oxygen content is below 100 ppm. Spherical powders are particularly useful in hot and cold isostatic pressing, where green strength is not a problem but the packing density of the powder in the container matters. Powders produced by gas atomization include aluminium, aluminium-silicon-10-magnesium, copper, bronze, zinc and brass.
Water-Atomized Copper Powder
Water-atomized copper powders have an irregular particle shape and therefore good green strength. The powder particles contain no internal porosity and have superior compressibility, especially because of the annealing step developed for hot pressing. Water-atomized powders are the preferred material where high green density is sought in powder-metal structural parts. The page states that production of copper and copper-alloy powders by water atomization is increasing; the powders produced include copper, bronze, iron, stainless steel and brass.
Water-Atomized Iron Powder
On the water-atomization page, the powder table lists iron powder at 99.9% purity, produced by water atomization. The stated sieve ranges are -20 µm (600 mesh), 20-45 µm (325 mesh), 45-63 µm (230 mesh), 63-90 µm (170 mesh), 90-125 µm (120 mesh) and +125 µm (100 mesh). The same page lists copper, bronze, stainless steel and brass powders among the powders produced by water atomization, together with iron powder. Atomization is formed when a high-energy liquid or gas breaks up molten metal.
Services
Metallographic Examination and Hardness Testing
The R&D laboratory has an AOB Mount-1 LHM-3000 metallographic cutter, an AOB automatic metallographic cutter and an AOB POL-1 grinding and polishing machine for sample preparation. Hardness is measured with an AOB Brinell-Rockwell and Vickers hardness tester. Powder characterization uses a Carpenter Additive flow and apparent-density instrument and a KERN ABJ 220-4 NM analytical balance. The fume hood is a Hedlab X-Pro. This equipment is used to support companies and universities with laboratory services.
Powder Chemical Analysis and Particle Measurement
In the R&D laboratory, the chemical composition, size and shape of the powders produced in-house are measured. Chemical content is analysed with an X-Ray PANalytical Epsilon 1, particle size with a Malvern Mastersizer 3000, and particle shape with a Nikon Type 104 C microscope. The laboratory supports national and international companies and universities with the laboratory services they need.
Powder Metal Parts Manufacturing
In 2021, at its factory in the HAB Ankara Aerospace and Aviation Specialized Organized Industrial Zone in Kahramankazan, Karakoyunlu Group A.Ş. began production and sales of powder-metal parts under the TMC Powder Metal brand, alongside metal and non-metal powders. Production is oriented to the defence industry. The about page names Prof. Dr. Mustafa Boz as consultant. The plant address is Saray OSB Mahallesi, Sabiha Gökçen Bulvarı No: 16/1, 06980 Kahramankazan / Ankara.
