Tantalum Box Heaters

1. Product name:  Tantalum box heaters

The texture of tantalum box heaters is very hard, and the hardness can reach 6-6.5. Its melting point is as high as 2996℃, and its thermal expansion coefficient is very small. Tantalum box heaters also have excellent chemical properties and extremely high corrosion resistance. It has no reaction to hydrochloric acid, concentrated nitric acid, and "aqua regia" under both cold and hot conditions.

2. Metal tantalum is a kind of slightly blue light gray metal. Due to its many exotic properties, it has a wide range of applications. Therefore, it is known as the all-rounder of the "metal kingdom".

3. Tantalum boat box production process: molybdenum slab - blanking - semi-finished product multi-pass rolling - finished product rolling - shearing - wire cutting - bending - riveting - cleaning - inspection

4. Our company and factory:

Baoji Magotan Nonferrous Metals Co., Ltd has many years of experience in non-ferrous metal production and processing, and a long-term commitment to export trade, the tantalum box heaters produced by Magotan have high flatness and long service life. Tantalum box heaters of various sizes and shapes can be customized according to customer requirements.

5. Expand knowledge:

Classification of coating types:

The type of coating can be divided into two types: dry coating and wet coating.

Among them, dry coating mainly includes: vacuum evaporation coating, sputtering coating, vacuum ion coating.

 Vacuum evaporation coating can be divided into:

1)Resistance evaporation coating (suitable for evaporating low melting point materials, such as gold, silver, zinc sulfide, magnesium fluoride, chromium trioxide, etc.)

2)Electron beam evaporation coating (can evaporate refractory metals, such as molybdenum, tungsten, germanium, silica, alumina, etc.)

3)High-frequency induction heating evaporation coating (the evaporation rate is high, the temperature of the evaporation source is stable, the operation is simple, and the material purity requirements are wide.)

4)Arc heating evaporation coating (especially suitable for materials with high melting point and certain conductivity, such as graphite; the device is simple and cheap, the disadvantage is that the micron-sized particles generated by the discharge will affect the consistency of the film)

5)Laser beam evaporation coating (can evaporate any high melting point material)

6)Reactive evaporation coating (evaporation of refractory compounds, such as magnesium fluoride, barium oxide, tin oxide, etc.)
