We believe materials have been a key element in promoting the progress of mankind; they are the heart of today’s life and will continue to be leading players for the creation of future wealth. We believe that the metals connected to materials play a vital role, that they can be efficiently and infinitely recycled and that this makes them the basis for sustainable products and services. We want Umicore / Italbras to be a leader in supplying and creating solutions with the base materials that contribute to noticeably improve the quality of life. -3-

Ecological Brazing Alloys without Cadmium BrazeTec Ecological Brazing Alloys in Compliance with RoHS and REACH 494/2011 The silver-based brazing alloys on this page can be defined as ecological since they do not contain any metals deemed dangerous in the workplace, in compliance with the RoHS and REACH 494/2011 regulations. The alloys can be generally used for operating temperatures going from -200ºC up to +200ºC. They can be used to braze any type of steel, copper and its alloys, nickel and its alloys. When stainless steel is brazed, the presence of zinc in the alloy can cause corrosion,...

Copper-Phosphorus Alloys and Copper Alloys BrazeTec Brazing Alloys Containing Phosphorous for Copper and Copper Alloys Brazing alloys containing phosphorous can be generally used for operating temperatures going from -55ºC to +155ºC. The alloys have been developed specifically for copper-to-copper or copper-to-copper alloys (brass, bronze) junctions. When copper is brazed with copper it is not necessary to use any flux due to the content of phosphorus in the alloy. When copper is brazed with a copper alloy, flux must be used. The use of these alloys in junctions in contact with sulphur is...

Brass, Bronze and Silversmiths’ Alloys Braze Tec Brass and Bronze Brazing Alloys Bronze and brass alloys are particularly recommended for brazing galvanized iron, steels and cast iron for deposit layers, Nickel and its alloys, always using flux.

CuproBraze Pastes BrazeTec Brazing Pastes for CuproBraze The CuproBraze process was developed primarily for brazing copper-brass radiators without de-oxidant, in protected atmosphere furnaces. In this application a copper-based brazing paste containing phosphorus is used. The pastes can be applied by spraying or roller-coating and can also be used to braze copper with copper. A special thermoplastic paste exists that is solid at ambient temperature and liquefies at 70° C.
