Riveting requires the use of a rivet gun and a tungsten alloy bucking bar. Typically, the bucking bar is designed in various shapes and sizes depending on the rivet gun being used. In some cases, dedicated tungsten bucking bars may be designed for specific riveting tasks.

LED chip probing and LED mapping sorting are necessary and important processes in the production of LED products. 

Tungsten granules, also known as tungsten flux, are made by breaking forged tungsten parts. 

Tungsten-copper protective tube is a composite material tube, made from a blend of 93% tungsten and 7% copper. 

In the first half of April 2024, the prices of high-grade wolframite concentrate from main China tungsten companies were 128,500 yuan per standard ton, an increase of 2,500 yuan per standard ton compared to the second half of March 2024.

In the first half of April 2024, the long-term contract prices (including 13% value-added tax) of main China tungsten companies for wolframite concentrate (WO3≥55%) were 126,500 yuan per standard ton, an increase of 2,000 yuan per standard ton compared to the second half of March 2024. For scheelite concentrate (WO3≥55%), the prices were 125,500 yuan per standard ton, an increase of 2,000 yuan per standard ton compared to the second half of March 2024. And for ammonium paratungstate (APT) (national standard grade), the price was 188,500 yuan per ton, an increase of 3,500 yuan per ton compared to the second half of March 2024.

In the first half of April 2024, the long-term purchase price of ammonium paratungstate (APT) of main China tungsten company was 187,500 yuan/ton, an increase of 2500 yuan/ton from the second half of March 2024.

The barium tungsten cathode is composed of a porous matrix uniformly filled with barium salt. The barium oxide component in the barium salt easily absorbs moisture and other impurities. To ensure the effectiveness of the barium tungsten cathode product, it is required not to be exposed to the atmosphere for more than 48 hours before use, and maximum efforts should be made to prevent moisture, dust, and other pollutants from contacting the product.

To ensure optimal performance, all operations on the electrode should be carried out in a very clean, dry environment. Oil stains or other contaminants on the fingers can affect the activation of the electrode and the performance of the final finished lamp.

Nano tungsten oxide can be used as a raw material for lithium battery cathodes due to its high theoretical specific capacity and good conductivity.

The price of nano-tungsten oxide for lithium batteries is USD55/kg, FOX XIAMEN, CHINA (adjusted according to quantity)

Delivery time 20 days

Packaging: 25KG or 50KG/barrel

Tungsten alloy sheet is widely used in aerospace, medical fields and electronic equipment.

Shielding windows and shielding blankets in space capsules: Tungsten alloy sheets are used in aerospace as shielding windows and shielding blankets to shield space rays and protect electronic equipment and the human body.

Radiation shielding: Tungsten alloys are non-toxic and safer than lead. The high density makes tungsten alloy plates have better radiation shielding capabilities, and their radiation shielding capabilities are not affected even under extreme conditions. Tungsten alloy sheets can be used to make multi-leaf grating blades. The multi-leaf grating system in radiation medical technology consists of 120 tungsten alloy grating blades.

Heat sink: Tungsten alloy sheet has the advantages of good thermal conductivity and low expansion coefficient. Moreover, tungsten alloy sheet is non-magnetic and is very suitable for use as heat sink for high-power LED chips. Tungsten alloy sheets can also be used in housings and heat sinks for computer chips and integrated circuits.
