Compounds

Due to its outstanding wear resistance and tribological properties, PTFE is used as a sliding material (e.g. in bearings) and in seals.  In combination with copper or bronze powders as technical compounds, their density, strength and thermal conductivity are improved significantly.

Cubrotec

Lamellar copper powders for use in contact materials, lubricants and in the chemical industry are produced when copper powder atomized in air is processed in the following ball milling procedures.

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.
