Copper Development Association UK

---

The Copper Development Association, 1933-2019, was a non-trading organisation.

To promote the cost-effective use of copper and copper alloys, in 1933 the leading producers of copper collaborated with the majority of industrial fabricators and processers to create an Association for the proper support and development of the markets. Mostly the producers were members of the London Metal Exchange and they provided the majority of the finance. Many members of the British Non-Ferrous Federation (BNFMF) and the Association of Bronze and Brass Founders (ABBF) subscribed and at one time there were about 600 members of the Copper Development Association (CDA) in the UK.

Aims

The aims were declared as: To encourage and promote the efficient application of copper and copper alloys in all forms.

• To provide a link between research and its industrial applications, including both commercial organisations and the general public.
• To disseminate technical information and provide an advisory service on all matters concerning the use of copper and its alloys.

Sister CDAs were also set up in other countries, notably the American CDA (Inc).

Efforts were aimed at benefiting many industrial sectors such as the electrical industry, brass components for all industries, building and construction uses such as plumbing and roofing, chemical and biological usage and marine environments. With the reduction in the number of fabricators and reorganisations within the producers, increasing efficient international cooperation became vital. The offices of CDA UK were closed in 2003 and the work taken over by the Copper Alliance of the International Copper Association (ICA).

The International Copper Association (ICA) has been working on behalf of the copper industry for more than 60 years, beginning in 1959 with its predecessor organization, the International Copper Research Association (INCRA).

Copper’s capacity for health and healing was discovered by ancient civilizations. As modern science continues to shed light on the relationship between copper and health, copper is playing a greater role in healthcare, being antimicrobial and an essential trace element.

Pure copper has the best electrical and thermal conductivity of any commercial metal. Over half of the copper produced is used in electrical and electronic applications. There are also more than 400 copper alloys, each with a unique combination of properties to suit many applications, manufacturing processes and environments. These include, amongst others, the brasses, bearing bronzes, aluminium bronzes, nickel-silvers and copper-nickel alloys.

Council

The finances of CDA were controlled by a small Council formed from principal members.

Industry Committees

The technical work was guided by industry committees formed to promote applications and conduct projects for applications such as: electrical efficiency, best practice plumbing and roofing Copper_in_architecture, brass applications, aluminium bronze and cupronickel seawater systems

Qualified Technical Staff

Latterly these included: Martyn Stamford, Richard Dawson, Dr Geoff Greetham, Dr Agnes Segal, Nick Hay, Ken Kempson, Carol Powell & Lou Brown. Specialist consultants were also used for some of the projects.

Cooperation

Liaison links in the Copper Industry. Abbreviations in the text.

The diagram shows the effective cooperation that existed in the copper industry. It reflects the situation in 1983 and there have been some changes since, especially with the formation of the Copper Alliance. The BNFMTC used to be known as the BNFMRA British Non-Ferrous Metals Research Association.

CIDEC Data Sheets (International Copper Development Council,) cooperative work agreeing typical compositions and properties of coppers and copper alloys in extensive detail.

CIPEC (Intergovernmental Council of Copper Exporting Countries) including initially Chile, Peru, Zaire and Zambia plus Australia, Indonesia, Papua New Guinea and Yugoslavia. 1967 – 1988.

ICIBulletin – a quarterly summary of abstracts of papers published world-wide.

BSI – CDA helped to represent copper interests on about 30 committees of the British Standards Institution and hence the ISO (International) and CEN (European) standards. British Non-Ferrous Research Association (Later BNFMTC)

Copper Ankh

The 1933 CDA Ankh logo

The CDA ankh 1970s

The last version of the copper ankh symbol

Pre-dynastic Egyptians knew copper very well and in hieroglyphs copper was represented by the ankh symbol which was also used to denote eternal life. This early appreciation of the lifetime cost-effectiveness of copper and its alloys made it the obvious choice for the corporate logo for many years. However, confusion with other meanings was avoided when its use was discontinued in 2000.

Educational Activities

CDA was highly respected by lecturers and teachers for the provision of much material suitable for their syllabuses in physics, chemistry, biology, metallurgy, engineering, architecture, plumbing and roofing. Publications, graded by age range, including books, videos, datadiscs and wallcharts were provided free of charge.

Although CDA material is no longer available directly, some has been digitally recorded and is available for schools, apprentices and undergraduates.

Association for Science Education. School Science Has zip folders of digitised publications for specific age groups under the titles of General Interest, biology , chemistry and physics.

Achievements

Each year the annual report detailed the progress made including the results of publications written or revised, exhibitions attended, cooperation with government and industry sectors and special promotional programmes. The work of CDA was promoted with occasional articles in the technical press. and

Publications

To provide the best information service for users of copper and copper alloys for all types of applications, CDA published an extensive number of publications. Initially they were mostly hard backed octavo books of about A5 size. They were updated with successive editions as technology developed. Later, the A4 format was adopted, and the soft cover booklets were called ‘Technical Notes’ which replaced some of the earlier books. There were also Information Sheets dealing with specific application examples. After 1992, the variety of publications was then simplified by sequential numbering. Most were not given ISBN registration (International Standard Book Number). Miscellaneous publications included conference proceedings and reprints of published papers. Latterly, publications were also made available in data disk format, as educational information sheets and as wallcharts.

CDA publications have been listed compiled from available literature and the index of the British Library. None are now available new from CDA but may be found second hand or at The British Library reading room at St Pancras, London. More recent publications emphasise environmental considerations and are published by the European Copper Institute.
