Ultra Pure Copper Products
For the most demanding applications requiring the highest purity of copper It all begins with high-purity copper
As even small impurities can have a significant negative influence on the desired results, therefore we never compromise the purity of our raw materials. Our finished and semi-finished products are all made from the very highest purity copper.
We produce our own proprietary oxygen-free copper from only the best quality cathodes. This vertical integration gives us complete control over the quality and supply of our raw materials and products.
Oxygen-free coppers and copper alloys used:
99.9995% (5N5)
OFE-OK® (4N5) 99.995% (5N)
99.995% (4N5)
Other oxygen-free coppers and copper alloys, such as CuP
Sputtering targets
UKLT has a long history of developing the challenging sputtering targets and blanks for the targets together with our customers. The products are based on high quality copper with very homogenous structure.
Copper anodes
UKLT offers the best copper anodes for the most advanced electrochemical deposition (ECD) semiconductor systems. Those have been developed over several decades together with the high-end companies.
The products can be precision machined products directly into the clean room or semi-finished components for the customer's own manufacturing.
High-purity copper pellets
UKLT specialises in the refining and fabrication of high-purity copper pellets for physical vapor deposition (PVD) and electrochemical deposition (ECD).
The products could be customer specified from the very small pellets to the bigger balls or slugs. The purity range is 4N5 – 6N (99.995%-99.9999%). Also special alloys like CuP and CuIn are available.
Ultra-pure coppers cryogenic components
UKLT is a leading manufacturer of semi-finished products for all kinds of applications where high-quality copper is essential. We can produce customer-specific semi-finished products in all shapes and sizes, including bars, sheets, tubes and machined components. We can also supply ingots in all the high-purity copper grades.
It has developed the copper grades for the cryogenic applications. The best-sold alloy is OFE-Cryogenic. The RRR (Residual-resistivity ratio) is 250 – 450. Even higher RRR values could be get by using ultra-pure coppers (Cu 99.999 – 99.9999%). Then RRR values are 800 – 2000.
