What is BS 3907-7 – Magnesium and magnesium alloys about?
BS 3907-7 standard is a part of the BS 3907 series that discusses the determination of nickel in magnesium alloys using the photometric method for the analysis of magnesium and magnesium alloys. The advantage of magnesium alloys to be used in such applications is their lightweight, high strength-to-weight ratio, high stiffness-to-weight ratio, castability, machinability, and great damping.
Who is BS 3907-7 – Magnesium and magnesium alloys for?
BS 3907-7 on magnesium alloys applies to:
- Manufacturer of magnesium products
- Quality testing personnel
- Aerospace industries
- Designing engineers
Why should you use BS 3907-7 – Magnesium and magnesium alloys?
Nickel Magnesium Alloys are master alloys of Magnesium with Nickel. They facilitate small additions of Magnesium to Iron, which transforms graphite flakes into spheroids. This group of alloys was the first to be used for S.G. Iron production. Photometric measurement, or photometry, is a technique that can be used to measure the concentration of organic and inorganic compounds in solution by determining the absorbance of specific wavelengths of light.
BS 3907-7 provides you with the principle of nickel in magnesium alloys using the photometric method in which the alloys are dissolved in acid, the dimethylglyoxime complex of the nickel is formed in ammoniacal citrate solution and the complex is extracted with chloroform. The nickel complex is then extracted from the chloroform with dilute hydrochloric acid and, after the addition of bromine water, the solution is made ammoniacal and dimethylglyoxime added. The method is recommended for nickel contents between 0 001 % and 0.02 %.
With obedience and compliance to BS 3907-7, you can efficiently manufacture high-quality magnesium alloys using the determination of nickel.
