Corrosion Behaviour and Protection of Copper and Aluminium Alloys in Seawater, Volume 50

This is achieved by the alloying process: to produce a solid material out of two or more different metals. By combining copper with other metals, a range of copper alloys can be made to fit almost any application. There are more than copper alloys, each with a unique combination of properties, to suit many applications, high quality requirements, manufacturing processes and environments. Pure copper has the best electrical and thermal conductivity of any commercial metal. Click on the boxes below to read more.

Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion. The best known traditional types are bronze , where tin is a significant addition, and brass , using zinc instead.

In exposure tests were started in Sweden to gain knowledge of the natural patination and the corrosion behavior of copper and copper alloys when used outdoors. The investigation covered 36 alloys in sheet or rod form: 5 coppers, 20 brasses, 5 phosphor bronzes, 1 silicon bronze, 1 aluminum bronze, 1 cadmium bronze, 2 nickel-silvers, and 1 free-cutting phosphor bronze. Specimens were exposed in rural, marine, and urban atmospheres. After two- and seven-years' exposure, specimens were examined. During the first years of atmospheric exposure the copper and copper alloys acquired a dark surface coating consisting mainly of copper oxide Cu 2 O.

Copper and copper alloys

Brasses have have a interesting combination of mechanical properties and easiness to manufacture complex parts. The Cu- und Zn alloys are non-magnetic and expose good tribological properties. The higher the Zn content, the better are the mechanical properties, however cold-formability decreases. The use of brass is reduced in many applications because of the poor mechanical strength and because of the low relaxation resistance at high temperature in connector technology applications. Leaded brasses offer excellent machinability.

Part 1 Overview on copper and aluminium alloys: Corrosion behaviour of non-ferrous alloys in sea water in Polish marine industry; Erosion-corrosion interactions of copper and aluminium based alloys. Part 3 Aluminium bronzes: Long-term and accelerated corrosion testing methods for cast nickel aluminium bronzes in seawater; Galvanic corrosion of nickel-aluminium bronze coupled to titanium or CuNi alloy in brackish seawater. Part 4 Aluminium alloys: Corrosion and protection of aluminium alloys in seawater. Part 5 Aluminium based anode material: Electrochemical of the performance of new aluminium alloys as sacrificial anodes; Low voltage aluminium anodes optimization of the insert-anode bond; Improvement of the performance of al-zn-in anode in seawater by control of casting parameters and alloying elements.


Brasses are alloys made from copper and zinc, they exhibit good strength and ductility and are easily cold worked, properties which improve with increased zinc​.

Но сразу же об этом пожалел. Глаза немца расширились. - Was tust du. Что вы делаете. Беккер понял, что перегнул палку.

Фонтейн смотрел в окно, пытаясь понять, что происходит. За несколько лет работы ТРАНСТЕКСТА ничего подобного не случалось. Перегрелся, подумал .

Сьюзан это выводило из себя, однако она была слишком самолюбива, чтобы пожаловаться на него Стратмору. Проще было его игнорировать. Хейл подошел к буфету, с грохотом открыл решетчатую дверцу, достал из холодильника пластиковую упаковку тофу, соевого творога, и сунул в рот несколько кусочков белой студенистой массы.

 - Мне кажется маловероятным, что Танкадо использовал непроизвольный набор знаков. - Выбросьте пробелы и наберите ключ! - не сдержался Бринкерхофф. Фонтейн повернулся к Сьюзан. - Как вы думаете, мисс Флетчер. Сьюзан задумалась.

Сьюзан стукнула кулаком по столу: - Нам необходимо это кольцо. Ведь на нем - единственный экземпляр ключа! - Теперь она понимала, что нет никакой Северной Дакоты, как нет и копии ключа. Даже если АНБ расскажет о ТРАНСТЕКСТЕ, Танкадо им уже ничем не поможет. Стратмор молчал. Положение оказалось куда серьезнее, чем предполагала Сьюзан.

 Да. Он уверяет, что в шифровалке полный порядок. Сказал, что ТРАНСТЕКСТ работает в обычном темпе. Что у нас неверные данные. Джабба нахмурил свой несоразмерно выпуклый лоб.
