Brazing Wikipedia

Brazing is a metaljoining process in which two or more metal items are joined together by melting and flowing a filler metal into the joint, the filler metal having a lower melting point than the adjoining metal.. Brazing differs from welding in that it does not involve melting the work pieces and from soldering in using higher temperatures for a similar process, while also requiring much ...

prevents further oxidation of the copper. When the copper is heated (, by bad connection), more oxides are formed. These highresistance oxides will continue to increase the heat until the conductor breaks. At temperatures above 88 EC (180 EF), copper oxidizes in dry air. Copper is oxidized in an ammonium environment and is also affected by ...

From Ore to Finished Product

Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (coppertin alloy) about 3000 BC, was the first engineering material known to man.

Cathodic protection Wikipedia

Cathodic protection (CP) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects the metal to be protected to a more easily corroded "sacial metal" to act as the sacial metal then corrodes instead of the protected metal.
