1 Alloy Designation EN DIN CEN/TS Hig Performance STOL Alloys UNS * * Sligtly different composition Cemical Composition percentage Cu including Ag 99.2 % Sn.2 % Mg % Ag.1 % Tis alloy is in accordance wit RoHS 22/96/CE for electric & electronic equipments and 22/53/CE for automotive industry. We ave developed a wide range of ig performance copper alloys wit excellent properties regarding conductivity, strengt, corrosion beaviour, bend ability and relaxation properties. STOL alloys are te first coice materials for ig-end applications and products. Caracteristics is alloyed wit low Silver (Ag), Magnesium (Mg) and Tin (Sn) to acieve a ig strengt combined wit very good conductivity. I as good relaxation properties, ig softening resistance and oxidation stability. Main Applications Electrical: Coutators for Electric motors, Flexing Switc Parts, Tinsel Wire, Wire, Hig Strengt for Aircraft Hook Up, Contacts, Fittings, Electronic Components, Conductors in Solid State Devices, Electrical Connectors, Lead Frames, Resistors, Current bridges, Fasteners: Clamps Industrial: Diapragms, Heat Sinks, Resistance Welding Electrodes, Hig Conductivity, Ligt Duty Springs Preferred Applications Spring Contact Components for Printed Circuit Board Current Carrying Capacity x xx xx x = well suited xx = particularly well suited Pysical Properties Typical values in annealed temper at 2 C Density 8.9 g/cm³ Termal expansion coefficient C /K Specific eat capacity 385 J/(g K) Termal conductivity 33 W/(m K) Electrical conductivity (1 MS/m = 1 m/(ω ²) 46 MS/m Electrical conductivity (IACS) 79 % Termal coefficient of electrical resistance (.. 1 C) /K Modulus of elasticity ( 1 GPa = 1 kn/²) cold formed annealed 125 GPa GPa Page 1

Bending Radius R/T bending edge transvers to rolling direction bending edge in rolling direction 9 Bending Bending test according to EN ISO 7438 is done wit 1 wide samples. Smaller samples in general as well as lower tickness allow a lower bending radius witout cracks. If needed we supply bending optimized temper classes tat far exceed standard quality. Please take care wen comparing wit ASTM E 29 results, tere te bend definition direction is contradictory. Bending Definition R32 R39 R44 R48 Transverse = good way Parallel = bad way rel.

Tis metod is taking sort time relaxation into account. so tat te values acieved are very realistic, wile oter test metods like tube test pretend better properties from te acieved 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. te beaviour of deformed parts may differ. neverteless te ratio between te different tempers remains te same. Typical test sample tickness is.3.6. Page 4

5 Page 5 Sanitary and Antimicrobial Properties Marc Solioz. University of Bern Copper as been recognised as a ygienic material since te dawn of civilisation and, in te last two centuries, te anecdotal evidence as been supported by scientific researc sowing tat copper is antimicrobial, i.e. it inibits te growt of armful patogens - bacteria, moulds, algae, fungi and viruses. Due to its ig copper content of about 99% provides te full antimicrobial properties of copper to inibit te growt of bacteria, viruses and fungi wic are in contact for a sort period of time on copper containing surfaces. Copper surfaces ave sanitizing properties and self-sanitizing activity tat make it attractive for ygienic and sanitary use e.g. in ospitals, nursing omes and oter ealtcare facilities or public buildings. Te effect as 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.

Te diagram sows typical values Time [s] Bend Fatigue (at room temperature) Te fatigue strengt gives an indication about te resistance to variations in applied tension. It is measured under syetrical alternating load. Te maximum bending load for 1 7 load cycles witout crack is measured. Dependent on te temper class it is approximately 1/3 of te tensile strengt R m.
