Soldering and joining components
Copper and copper alloy powders are used on a large scale in solder pastes for soldering and connecting metal components (heat exchangers, coolers, etc.) in the automotive and electrical device industries.
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.
|Apparent density [g/cm³]||Copper content [%]||flowability||Phosphorus content [%]||Sieve analysis [%]||Application|
|approx. 5||min. 99||flowable||max. 0.4||> 50 µm: max. 5||
|ca. 5||min. 99||fließfähig||max. 0.4||> 63 µm: max. 5||
|approx. 5||min. 99||flowable||max. 0.4||>100µm: max. 5 < 50µm: max.10||
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.
|Apparent density [g/cm³]||Copper content [%]||flowability||Phosphorus content [%]||Sieve analysis [%]||Tin content [%]||Application|
|approx. 5||approx. 96||flowable||max. 0.4||> 63µm: max.5||approx. 4||
|approx. 5||approx. 90||not flowable||max. 0.4||> 25µm: max.5||approx. 10||
|approx. 5||approx. 90||flowable||max. 0.4||> 80µm: max.5||approx. 10||
