Copper Powders
A wide range of different qualities of copper powders with various apparent densities is available. Each grade is produced from high quality refined copper and is very carefully fabricated in order to satisfy precisely controlled levels of quality tolerances. These powders are characterized by good flow ability, high green strength values, and are ideal for the industry of sintered parts. Choices of the most suitable quality will depend on the processing requirements.
Other applications of copper powders are in the production of catalysts, electrical contacts, alloying element in iron powders for enhancing strength properties and corrosion resistance and for brazing.
Specific qualities of oxide-reduced copper have lately been used as basic metal component in the industry of friction materials.
Bronze Powders
Several classes of bronze powders with different chemical compositions and particle sizes are produced. Thorough alloying of molten constituents enables obtaining homogeneous powders after atomization.
The other classes of bronze powders containing nickel and higher percent of tin can be fabricated on request. These powders are widely used in production of porous bronze bearings, sintered structural components of high density, as well as diamond tooldies.
Mixed bronze powders are a special developed range of bronze mixes to satisfy the demands of the porous bearing producers, using precisely controlled contents of the constituents such as graphite or Fe. Uniform mixes are obtained with reproducible apparent density and such properties of sintered bearings or structural components and their dimensional changes as to satisfy the customer's requirements for particular sintering conditions.
Brass Powders
Several standard qualities of prealloyed brass powders are available for use in the industry of friction materials and sintered parts. However, powders with other compositions and sieve fractions can be supplied on request.
One specific application of the brass powder alloyed with 2% of Al is in the production of golden bronze.
Copper Oxides
Copper oxides (Cu2O and CuO)are obtained by oxidation, grinding and separation from pure copper chips. Quality of the oxide is characterized by the percentage of oxygen, grain size and the developed surface. Cuprous oxide Cu2O is most often used as a basic component in the production of anti-fouling paints for vessels, then as a additive in alloying of iron powders, as well as in the production of plant protective.
Copper oxide CuO has most extensive application in the chemical, ceramic and porcelain industry and for special purposes.
Lead Powders
Lead powders are produced by air atomization of molten lead blocks of high purity. We offer a wide range of qualities with different particle sizes, although we can also produce special qualities at our customer's request.
Lead powder is extensively applied in the chemical, rubber, ceramic industry, we well as in the industry of friction materials. Lead alloy powders are also included, such as PbSb14, PbSn1, and so on.
Tin Powders
Tin powders are produced by air atomizating molten blocks of high purity. We offer a wide range of qualities with different sieve analyses and various values of the developed surface. Tin powder of standard quality (200 mesh) is used in copper mixes for the manufacture of porous self-lubricating bearings, whereas other qualities have special applications.
Zinc Powders
Zinc based powders are produced by air atomization of molten blocks of high purity. We offer a wide range of qualities with different sieve fractions, from the powder for friction materials (-630 + 100 microns) to very fine powders under 40 microns. Zinc powder of standard quality is used for zinc electrolysis. Furthermore, zinc powder is used for battery filling, in the industry of paints, for special purposes.
