Smaller samples in general – as well as lower thickness – allow a lower bending radius without cracks. If needed we supply bending optimized temper classes that far exceed standard quality. Please take care when comparing with ASTM E 290 results, there the bend definition direction is contradictory.

This method is taking short time relaxation into account. so that the values achieved are very realistic, while other test methods like tube test pretend better properties from the achieved values. Relaxation values give an indication about stress relieve of strip under tension for a certain time and temperature. As it is measured on plain strip. the behaviour of deformed parts may differ. nevertheless the ratio between the different tempers remains the same. Typical test sample thickness is 0.3 – 0.6 mm. 0 10 20 30 40 50 60 70 80 90 100 10 100 1000 10000 Time [h] R em ai ni ng S tre ss [% ] R460 100°C R460 150°C R460 200°C P kt (XY) 4 0 10 20 30 40 50 60 70 80 90 100 10 100 1000 10000 Time [h] R em ai ni ng S tre ss [% ] R460 100°C R460 150°C R460 200°C P kt (XY) 4 0 10 20 30 40 50 60 70 80 90 100 10 100 1000 10000 Time [h] R em ai ni ng S tre ss [% ] R460 100°C R460 150°C R460 200°C P kt (XY) 4 Initial Stress: 50% of Rp0.2 Parallel Rolling Direction Initial Stress: 80% of Rp0.2 Transverse Rolling Direction Initial Stress: 80% of Rp0.2 Parallel Rolling Direction Initial Stress: 50% of Rp0.2 Transverse Rolling Direction CuSn0.15* C14410 STOL®80 Industrial Rolled Page 5 Bend Fatigue (at room temperature) The fatigue strength gives an indication about the resistance to variations in applied tension. It is measured under symmetrical alternating load. The maximum bending load for 107 load cycles without crack is measured.

University of Bern Copper has been recognised as a hygienic material since the dawn of civilisation and, in the last two centuries, the anecdotal evidence has been supported by scientific research showing that copper is antimicrobial, i.e. it inhibits the growth of harmful pathogens - bacteria, moulds, algae, fungi and viruses. Due to its high copper content of about 99.8% STOL®80 provides the full antimicrobial properties of copper to inhibit the growth of bacteria, viruses and fungi which are in contact for a short period of time on copper containing surfaces. Copper surfaces have sanitizing properties and self-sanitizing activity that make it attractive for hygienic and sanitary use e.g. in hospitals, nursing homes and other healthcare facilities or public buildings. The effect has been verified in recent scientific studies on a range of disease-causing organisms including MRSA, Clostridium difficile, E.coli, Listeria monocytogenes, Influenza A (H1N1) and Aspergillus niger .
