Bolts that are not afraid of fire

Molybdenum bolts


“Molybdenum” is a metallic element, the element symbol is Mo, and the English name is Molybdenum. It is a silver-white metal. As a rare metal, “molybdenum” is widely used in various industries such as steel industry and petroleum. At the same time, various mechanical parts using “molybdenum” as raw material also appeared, such as our protagonist today – molybdenum bolts. Bolt is a very common part of our daily life. So what are the advantages of molybdenum bolts compared to ordinary bolts?

1. High temperature resistance

The main material of molybdenum bolts is molybdenum metal, and the purity of molybdenum is as high as 99.95%. The “molybdenum” used as a raw material has a very high melting point, so molybdenum bolts usually can withstand high temperatures up to 1600°~1700°. The melting point of stainless steel bolts is generally around 1300°~1400°. This means that in many cases, molybdenum bolts can meet the working requirements of many high-temperature environments that ordinary bolts cannot touch.


2. Excellent electrical conductivity

In addition to a high melting point, molybdenum bolts also have excellent electrical conductivity, which can be adapted to any equipment that requires electrical conductivity.

3. Good corrosion resistance

Parts made of many materials face the problem of corrosion and rust during daily use. Molybdenum, raw material of molybdenum bolts, does not react with hydrochloric acid, hydrofluoric acid and alkali solutions at room temperature, and is only soluble in nitric acid, aqua regia or concentrated sulfuric acid. It is also suitable for most liquid metals, non-metallic slag and molten glass. It is quite stable, so that molybdenum bolts also have good corrosion resistance.

4. Low coefficient of thermal expansion

Secondly, molybdenum bolts also have a low coefficient of thermal expansion. This advantage plays a very important role in the application of metal-ceramic structure, metal-semiconductor structure and metal-graphite structure.
