Tape, strip of molybdenum
Supplier — AvekGlob Company — offers at reasonable prices from the manufacturer molybdenum tape and strip. The supplier guarantees the timely delivery of products to any address specified by the consumer.
Technical specifications
Molybdenum tape and strip are produced in the annealed condition, in accordance with the technical requirements of GOST 25442−82 and TU 11−90 (the latter concerns products used for the manufacture of electronic devices). To obtain this type of rolled products, powder billets of molybdenum of M, MF and MF grades are used.
Urgency of application
Tape and strip of molybdenum is used for the production of hull details of the vacuum technique, which are manufactured using deep-drawing technology.
Chemical composition
The numerical data is given in percentages:
| Mass fraction of detectable impurities | Mass fraction of molybdenum | |||||||
| Aluminum | Iron | Nickel | Silicon | Calcium | Magnesium | Carbon | Oxygen | |
| 0.004 | 0.010 | 0.005 | 0.010 | 0.003 | 0.002 | 0.005 | 0.008 | Rest |
Notes:
1. It is permissible to increase the mass proportions of impurities of aluminum, iron, calcium, and magnesium, while retaining the sums of the mass fractions of aluminum + iron, calcium + magnesium.
2. The oxygen norm is determined at each lot and is indicated in the quality document. In accordance with the agreement with the consumer, this standard can be adjusted.
According to TU-11−90, annealed and unburned Molybdenum grades MCH and MPH are used for the production of electronic components, which contain, besides molybdenum, 0.018… 0.025% silicon, 0.005… 0.02% of a mixture of calcium and magnesium and not more than 0.014% carbon.
