Relief technique

Effect pigments, aluminium pigments, gold bronze pigments

With “relief technique”, “real” metal surfaces are created for artistic or craft purposes by working metal granulate into plastic, by pouring or modeling it into the desired form, and then using mechanical processing (grinding, polishing, brushing, etc.) to reveal the metal surface. Subsequent chemical processing can also achieve antique or patina effects.

Rogal Copper GK

Smelting and atomization are used to produce copper powders from highly pure refined or electrolytic copper.

In the air atomization process used by SCHLENK, spherical particles are formed , which are then classified into the required particle size distribution.

Rogal Brass

Brass is an alloy made of copper and zinc in various compositions. Air atomization of the molten material results in irregularly shaped powders. Common compositions are brass I (approx. 92%Cu/8%Zn), brass II (approx. 82%Cu/18% Zn) and brass III (approx. 70%Cu/30%Zn)

Rogal Tin Bronze GK

Alloying and atomization of copper and tin in air produces irregularly shaped bronze powder. Deoxidizing components (e.g. phosphorus) can be added to produce powders with light gloss, e.g. those needed in filter materials.

A standard alloy contains approx. 90% copper and 10% tin. Special alloys and the respective particle size distribution are part of the individual specifications and are ensured through effective process and quality control.
