蓝宝石炉用钨制品

纯钨钼产品是作为蓝宝石生长炉的重要材料。蓝宝石炉用钨制品主要是以纯度高于99.95%的钨原料生产而成的产品，包含钨坩埚、钨板、钨片、钨丝、钨电极屏、钨筒和钨隔热屏。其中，钨钨铼丝是以钨为主要材料生产出来的合金丝，常用规格为含铼25%的钨铼丝。

蓝宝石炉用纯钨产品

蓝宝石炉用纯钨产品是钢灰色至锡白色的坚硬金属，非常纯的钨可以拉锯锯开（纯钨很脆，不易加工）。钨的加工手段有锻造、拉伸和冲击。在所有金属中钨的熔点最高，为3415℃，蒸汽压最低，在抗张强度最高（1650℃时）。防腐性能非常好，大多数无机酸对其侵蚀很小。在空气里其表面形成一层保护性氧化物，但是在高温下会完全氧化。

Tungsten Rod

Tungsten's unique properties as a high performance material, including a melting point of 3410° C, low vapor pressure at elevated temperatures and low coefficient of thermal expansion, make tungsten rod of value in a variety of high temperature products and processes. Among them are glass-to-metal seal parts and support parts for lighting and electronics, silicon rectifier stud mounts and high temperature furnace components.

Composite Tungsten Electrode

Their performances can be much improved by adding two or more rare Earth oxides which are mutually complementary. The composite tungsten electrodes have thus become out of the ordinary in the electrode family

Yttrium Tungsten Electrode

Yttrium tungsten electrode mainly applied in military and aviation industry with narrow arc beam, high compressing strength, highest welding penetration at medium and high current.

Mainly applied in military and aviation industry with narrow arc beam, high compressing strength, highest welding penetration at medium and high current 

Zirconated tungsten electrode

Zirconated tungsten electrodes are good at the performance in AC welding, especially under high load current. These electrodes can retain a balled end when welding, which results in less tungsten permeation and good corrosion resistance.It balls up well in AC welding and has a more stable arc than pure tungsten.Especially with excellent performance in high load AC welding,it is not replacable by any other electrodes.It also resists contaminationwell in AC welding.

Cerium Tungsten Electrode

Cerium tungsten electrode is the electrode of tungsten added with 2%of CeO2.The power of its electronic transgression is 2.4ev,less than that of thorium-tungsten electrode .Its arc derivation voltage is also lower with better arc derivation function and higher arc power stability.The current allowed under the condition of anode direct current is higher and the burn spoilage is smaller.

Lanthanated Tungsten Electrode

The lanthanated tungsten electrodes are becoming more popular in the circle of welding in the world soon after they were developed, because of their good welding performance. The electric conductivity of lanthanated tungsten electrode is most closed to that of 2% thoriated Tungsten electrodes. 

Welders can easily replace thoriated tungsten electrodes with lanthanated tungsten electrodes at either AC or DC and not have to make any welding program changes.

Thoriated Tungsten Electrode

2% Thoriated Tungsten contains a nominal 2 wt-% or thorium oxide (ThO2) that is evenly dispersed throughout the entire length of the Tungsten. The most common type of Tungsten used today.  

Thoriated tungsten electrode provides excellent resistance from weld pool contamination while at the same time offers the welder easier arc starting capabilities and a more stable arc. Generally used for DC electrode negative or straight polarity applications such as carbon & stainless steels, nickel alloys and titanium.

Pure Tungsten Electrode

Pure tungsten electrodes the one without any addition of oxide. This allows the tip to form a clean, balled end which provides good arc stability on AC. The power of electronic transgression is as high as 4.5ev. Requiring a high voltage for arc derivation, it has a low current capacity and is easily burnt. It’s good for application under the condition of AC and in the situation of low welding requirements.

Pure tungsten electrode can form a clean, balled tip when heated and provides great arc stability for AC welding with balanced wave. Pure tungsten also provides good arc stability for AC sine wave welding, especially on aluminum and magnesium, but is not typically used for DC welding (it does not provide as strong of arc starts as thoriated or ceriated electrodes).

MSDS

What is MSDS?

Material Safety Data Sheet (MSDS) is a table about data regarding the properties of a particular substance, which may concern instructions for the safe use and potential hazards associated with a particular material or product. Therefore, MSDS is important and necessary for chemicals users.

The sheet aims to offer workers and emergency personnel with procedures for handling or working in a safe way, and includes information such as physical data (melting point, boiling point, flash point, hardness, ultimate tensile strength, density, etc.), toxicity, health effects, first aid, reactivity, storage, disposal, protective equipment, and spill handling procedures. The exact format for MSDS can vary from countries to countries by respective national requirement.

For example, below is part of the MSDS of tungsten electrode:
