Molybdenum wire should be stored in low humidity, cool and ventilated environment, storage temperature is as much as possible at 20 degrees ~25 degrees, it is easy to make molybdenum wire fast oxidation at humid environment. Molybdenum wires which are not used for a long time should be vacuum treated and stored. The thinner the wire diameter is, the shorter the oxidation time is. The suitable storage environment can guarantee the non oxidation of molybdenum wire for 1~2 months. After vacuum treatment, it can be kept for about 6 months. The vertical problems may occur when molybdenum wire is placed over 6 months.

Advantages of molybdenum wire:
The accuracy of molybdenum wire is high, and the line diameter tolerance is less than 0-0.002.
The breakage rate is low, the processing speed is high, and the cost performance ratio is high.
Stable long time continuous machining can be achieved.

The main features of unqualified molybdenum wire are as follows:
1. Unqualified wire cutting molybdenum wire, each disk length is less than 100-200 meters, which leads to insufficient net weight of molybdenum wire.
2. The unqualified wire cutting molybdenum wire coil weighing is 120-130g, or the actual coil weighing is 20~30g more than standard weighting. The net weight of molybdenum wire increases by 20-30g, and some of company wire weigh is about 98g.
3. The outside label data of non - standard cut molybdenum wire box does not tally with the number of wire disk labels.
