Distinguish True And False Through Waste Molybdenum Wire By EDM Wire Cutting During Processing

2024-01-05 18:00:06

We usually cut the molybdenum wire inside with the middle-travel wire, and the cutting mold is rubbed for a long time and it will be scrapped. However, the recycling price of the scrapped molybdenum wire is still very high, so how do we distinguish the true and false molybdenum wire? Below we decrypt this answer:

Generally speaking, because the unit price of waste molybdenum wire is relatively high, it is prone to fake products and other substances during the recycling process. In order to prevent users from being deceived, it is very necessary to master the identification method of waste molybdenum wire. Tell me how to identify the authenticity of molybdenum wire.

① Because the molybdenum wire has a high melting point, reaching more than 2500 degrees, it can be burned with a lighter when it is opened by hand (no need to be tight). Normally, it can be burnt at least ten seconds. If it is broken within 10 seconds, it is basically a fake. And the fakes usually bring sparks when they break off.

② The molybdenum wire is not magnetized, nor can it be attracted by strong magnetism. Therefore, if the molybdenum wire is attracted by a magnet, it is fake.

③ Tie the molybdenum wire tightly, (don't break it) and loosen it. You will see the molybdenum wire separate two or more.

④ Put a group of molybdenum wire on a gas stove and burn it in about a minute. The molybdenum wire will quickly oxidize to blue.

⑤ A ball of molybdenum wire, pour some concentrated nitric acid down and immediately emit yellow smoke. (Please use this method carefully, because concentrated nitric acid is very corrosive)

⑥ In the rolled waste molybdenum wire, if it feels too heavy, it may be adulterated with iron pieces. Pick up the molybdenum wire and fall to the ground. If there is a sound of hard objects hitting the floor, there may be iron pieces in the middle. If the molybdenum wire rolled into a ball has poor extrusion elasticity, there may be cloth pieces in the middle, it should be disassembled for inspection.

⑦ In addition, if there is more heavy oil and engine oil on the waste molybdenum wire, the weight should be discounted.
