Publication TN26 The Brasses - Technical Data

About this Publication

These data sheets, prepared by the International Copper Development Council (CIDEC), were originally published in a series covering all the main coppers and copper alloys in two large loose-leaf binders during the period 1968-72. 

They contain an invaluable summary of data relating to the physical and mechanical properties of the materials at low, ambient and elevated temperatures which is not available elsewhere. 

Tensile, hardness, impact, creep and fatigue data have been abstracted from the relevant original literature.  For the sake of accuracy, it is presented in bold type in the units in which it was originally published, together with lighter type equivalents in corresponding units.

Whilst this publication has been prepared with care, we can give no warranty regarding the contents and shall not be liable for any direct, incidental or consequential damage arising out of its use.

Introduction

Due to increasing demand from engineering designers and others for this type of information in readily accessible form, the decision was made to reprint the data sheets in bound form.  This booklet provided information relating to the brasses.  A second booklet covered the coppers in high conductivity copper alloys.  Since the original editorial facilities are no longer available, it has not been possible to update the information given.  Generally it will be found still valid.  For information updating the national and ISO specifications quoted for manufactured forms, refer to national standards organisations.
