Used for rudders,propellers and ship fittings ·Cupro-nickel (Cu-Ni) used for coins, tubes, wires,electrical resistances and thermocouples ·Nickel silver (Cu-Ni-Zn) used for marine applications,car radiators and fittings Brasses One the most important non-ferrousengineering alloys. They cover a largerange of physical properties and theirapplications are multiple. Copper is capable of holding about 39 % of zinc in solid solution. Alloys containing less than 39 % Zn are known as a-brasses. This brass (70/30) is very widely employed for cartridge, cases, condensertubes, etc. From 39 % to 46 % of Zn, a B-solid solution gives op-brass. This alloy (60/40) is found in extensive engineering applications with enhanced corrosion resistance used in marine applications. Alloys containing more than 49 % Zn are very hard and only used for brazing brasses. Bronzes Bronzes are used for bearing and gears. There are a widevariety of bronze alloys containing various elements suchas phosphorus, beryllium, silicon,etc.: · Leaded bronzes (Cu-Sn-Pb) are mainly used for bearingsdue to their good wear resistance Aluminum bronzes (Cu-Al) have good corrosionresistance but are difficult to cast. Used for pumps rods,diecastings, etc. (cont. on back page) ·Silicon bronzes (Cu-Sn-Ni) have high electricalconductivity and are used for wires · Phosphor bronzes (Cu-Sn-P) are used for valves,bearings and gears.

Please contactyour nearest Thermo office for the most recent values. The values listed in the general table are calculatedfrom the following formulae: and BLOD= limit of detection (3 sigma)= 3VQT where Q= counts per second per 1 % element B= background equivalent concentration T= time of analysis in seconds P= the percentage concentration at whichthe sigma value is calculated. The limits of detection are determined with low alloycopper samples. In practice, these values should agree withvalues measured practically using the mathematicalderivation of standard deviation (1 sigma). where the individual readings the arithmetic mean of the individualvalues n= number of determination (normally≥ 10) For guaranteed values, the values of precision and LODs should be multiplied by factor 1.5. Instrument calibration It should be stressed that an XRF spectrometer is a veryaccurate comparator, but the accuracy of the final analysisis entirely dependent on the quality of the standards usedfor calibration. The Thermo Scientific ARL 9900 XRFspectrometer, can be factory calibrated for various copperalloys or a general copper program using commerciallyavailable standards. It can also be calibrated on-site usingwell analyzed samples from the user. Conclusion The long experience of our company in metals analysiscomes from an installed base of over 1'000 XRFspectrometers world-wide. The ARL 9900 is the answer toyour metallurgical analysis needs; whether they beincoming material control, metal QC or productionanalysis. Working 24 hours a day and 7 days a week, theARL 9900 delivers dependable performance year afteryear. The high performance of the ARL 9900 will meetyour analytical needs today and in the future. In addition to these offices, Thermo FisherScientific maintainsa network of represen-tative organizationsthroughout the world. 朗铎投资控股(北京)有限公司全国统一销售电话:400-709-6161全国统一售后电话:400-010-9091 地址:北京市朝阳区高碑店乡西店村1106号源创空间大厦F026室 电话:010-87729275、010-87729285、18513915614传真:010-87729345邮编:100123网址:www.longduoholdings.com电子邮件:sales@longduoholding.com
