1 Page 1 Alloy Designation Hig Performance Alloys EN DIN CEN/TS UNS CW307G We ave developed a wide range of ig performance alloys wit excellent properties regarding conductivity, strengt, corrosion beaviour, bendability and relaxation properties. KME alloys are te first coice materials for ig-end applications and products. Cemical Composition percentage Cu Remainder % Al % Ni % Fe % Caracteristics CuAl10Fe4Ni5 combines ig strengt, ig cavitation -and erosionresistance. Good resistance against wear and good fatigue beaviour make is a preferred alloy for ig static and dynamic stress. Corrosion resistance, even in ot seawater is excellent. Due to te excellent welding properties it is a used for constructions of casted and wrougt parts. Main applications are sipbuilding, foodand cemical industry, taps and valves for aggressive waters. Tis alloy is in accordance wit RoHS 2002/96/CE for electric & electronic equipments and 2002/53/CE for automotive industry. Main Applications Industrial Valve Seats, Plunger Tips, Condenser Tube for Power Stations and Desalting Units, Safting, Pump Parts, Cams, Gears, Valve Guides, Aircraft Parts, Pump Safts, Structural Members, Corrosion Resistant Articles, Hydraulic Busings for Eart Moving Equipment, Valve Balls, Busings, Bearings, Heat Excanger Flanges, Heat Excanger Headers, Tanks, Welded Piping Systems, Balls Marine Nuts, Sip Propellers, Pump Parts, Bolts, Propellers Plumbing Faucets Pysical Properties Typical values in annealed temper at 20 C Density 7.58 g/cm³ Termal expansion coefficient C C /K 10-6 /K Specific eat capacity 0.42 J/(g K) Termal conductivity 51 W/(m K) Electrical conductivity (1 MS/m = 1 m/(ω ²) 4.6 MS/m Electrical conductivity (IACS) 7.9 % Termal coefficient of electrical resistance ( C) /K Modulus of elasticity ( 1 GPa = 1 kn/²) cold formed annealed 124 GPa GPa

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 290 results, tere te bend definition direction is contradictory.

Example: R/T = 0.5 and tickness 0.3 Minimum radius = (R/T) x tickness = 0.5 x 0.3 = 0.15 Bending Properties* Temper R R R R R Bending 90 Bending 180 Transvers Parallel Trans -vers Parallel R/T R/T R/T R/T under construction * Measured at sample widt 10 according to EN 1654 Possible bending radius = (R/T) x tickness

4 Page 4 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 81% 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. 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 10 7 load cycles witout crack is measured. Dependent on te temper class it is approximately 1/3 of te tensile strengt R m.
