Line Tungsten Wire with Two Ends

Line tungsten wire is all with the same direction spiral, and its ends are with two straight line with the direction the same to the spriral. Also the sprical numbers and ends lengths can be defined by customer. The followings are one drawing and one picutre with the end products. With the drawing and known dimenisons, the tungsten wire can be produced, like the picture.

The picture is with three strands, which belongs to type 3. The type 1 with single wire, type 2 double wires and type 4 three wires with one Al wire are the three most popular tungsten heaters for coating application.

Sprial Tungsten Wire with Two Legs

Sprial Tungsten Wire with Two Legs

Tungsten wire can be shaped to lots of shapes. attached is a kind of tungsten wire with door shape and two legs.

The spiral is to describe the center part, which is the upper part as the following picture. The sprial number is not defined and can be made according to the customer's requirement when they provided the value of "N". The picture is to show one of the tungsten wire, which is type 1, only with single wire.

Meanwhile,there are three more regular types, two strands, three strands and three plus one Al wire.

Detail Application of Cleaned Tungsten Wire

Important applications of cleaned tungsten wire are for the production
of coiled incandescent lamp filaments, cathode and support structures for power tubes, heating elements for high temperature furnaces and
evaporation sources in metalizing processes. Thicker wire sizes,
straightened, finish-ground and cut into rod pieces are widely used for
glass-to-metal seal lead parts in the lighting and electronic industries. The
materials can be made filaments for auto lamps, fluorescent lamps, high
pressure halogen lamps and other lamp components.

Cleaned Tungsten Wire Type and Application

Cleaned Tungsten Wire Type T
Double – screwy filament. Filament for high color temperature lamp and shockproof lamp etc.

Cleaned Tungsten Wire Type L
Filament for incandescent lamp. Cathode for emitting tube. High temperature electrodes. Twisted tungsten wire etc.

Cleaned Tungsten Wire Type W
Folded – heater for electronic tube, etc.

Black Tungsten Wire Cleaned in Hydrogen Atmosphere

Black tungsten wire cleaned in hydrogen atmosphere, in order to get cleaned tungsten wire. 

This method of cleaning surfaces on a metallic article, comprising the steps of: (a) disposing the article within a vacuum furnace; (b) heating the article to a temperature of about 1400° F. or above within the vacuum furnace; and (c) repetitively cycling hydrogen gas and a vacuum within the furnace by supplying in each cycle a fresh supply of hydrogen gas within the furnace at a pressure within a range of about 500-10,000 microns, followed by removal of reaction products resulting from a reaction between hydrogen gas and surface contaminants on the article and substantially all residual hydrogen gas from within the furnace.

How to Weld Pure Tungsten Material with Other Metals

It has been a very difficult and puzzling question: how to weld pure tungsten material with other metals?

As for the melting point is really different. Let is take pure tungsten and copper as example to show how to weld tungsten with copper together.

The melting point of tungsten is as high as 3410℃, but copper 1083 ℃, if we need to weld them together. Then we could choose tungsten electrode as welding consumables, and using TIG welding. Choosing tungsten electrodes can be made from pure tungsten electrode, thorium tungsten electrode, cerium tungsten electrode, lanthanum tungsten electrode and composite tungsten electrode.

Chinese couplet

Chinatungsten is located in Xiamen, Fujian, China, which has been a company which celebrates very traditional Chinese festivals. Spring Festival has been the most important one, and it has taken long holiday from Feb. 16, to Feb. 26. Feb. 27 is the first day for Chinatungsten members to come back for working.

Chinese couplet is very popular in China homes, not only on the house doors, but also on the animal’s doors, etc. Chinatungsten has not put this couplet, but put on “Fu” on doors and windows. If for homes, they always put this character on the wall of hall.

Introduction of Chinese couplet from Wiki.

In Chinese poetry, a couplet (simplified Chinese: 对联; traditional Chinese: 對聯; pinyin: duìlián) is a pair of lines of poetry which adhere to certain rules (see below). Outside of poems, they are usually seen on the sides of doors leading to people's homes or as hanging scrolls in an interior. Although often called antithetical couplet, they can better be described as a written form of counterpoint. The two lines have a one-to-one correspondence in their metrical length, and each pair of characters must have certain corresponding properties. A couplet is ideally profound yet concise, using one character per word in the style of Classical Chinese. A special, widely seen type of couplet is the spring couplet (simplified Chinese: 春联; traditional Chinese: 春聯; pinyin:chūnlián), used as a New Year's decoration that expresses happy and hopeful thoughts for the coming year.
