Tungsten sheet production steps

‌1,raw material preparation ‌ : Select high quality tungsten powder or tungsten strip as raw material for preliminary treatment and screening ‌

‌2,drying powder ‌ : Put tungsten powder in the oven for drying to ensure the dryness and stability of powder ‌

3‌,pressing molding ‌ : Put the dried tungsten powder or tungsten strip into the press for pressing, forming the required plate shape or normalized block ‌

4,Pre-burning: the pressed tungsten plate is put into the furnace for firing, so that its internal structure will become very dense.

5,hot pressing: the pre-burned tungsten plate is put into the furnace for high temperature hot pressing, the purpose is to enhance its strength again.

6,post treatment ‌ : the hot pressed tungsten plate is cut, polished, remove impurities and other treatment to make it meet the requirements of size and surface finish ‌

Tungsten sheet application

1,Vacuum coating ‌ : tungsten sheet is often used in the manufacture of electric vacuum furnace heating body and heat insulation screen, and electric vacuum electric light source parts, such as filament ‌

‌2, electric vacuum furnace ‌ : tungsten plate as heating element and heat insulation screen in electric vacuum furnace, has high melting point and good thermal stability, can withstand high temperature environment ‌

‌3,sporting goods ‌ : tungsten alloy plate is used for making dart rod, fishing pendant and other sporting goods ‌

‌4,balance weight: tungsten alloy plate can also be used in the oil drilling platform above the breeding device. And the counterweight on the fly hammer

5, electrode material: tungsten alloy sheet can be used to make electrodes, welding rods and other products

6,electronic package ‌ : Because tungsten alloy has high temperature resistance and good thermal properties, the electronic industry began to use tungsten alloy plate as electronic package ‌

‌7,nuclear energy ‌ : tungsten alloy sheet has a wide range of applications in the field of nuclear energy, including reactor structural materials, radiation shielding materials, nuclear fuel elements, absorption rods and radiation monitoring equipment base and support structure ‌

Characteristics of tungsten sheet

High tensile strength

The tensile strength of sintered high-density alloy is 800-1000MPa, and after hot processing, the strength can be increased to 1300-1500MPa. This high strength gives it an advantage in situations where high-strength materials are required.

Good ductility
High density alloy has good ductility, the elongation of sintered state can reach 10%-15%, after vacuum or atmosphere dehydrogenation treatment, the elongation can be increased by 20%-30%. This ductility makes it excellent in applications where plastic deformation is required.

Strong ability to absorb rays

The high density alloy has a 30%-40% higher ray absorption capacity than lead, and has better stability. This makes it important for applications where radiation shielding is required, such as medical treatment and radiation protection

Excellent electrical performance
Tungsten alloy has good electrical conductivity, electrical corrosion resistance and high voltage resistance, so that it has a wide range of applications in electric power, electronics and other fields.

Good thermal conductivity and low linear expansion coefficient
Its thermal conductivity is 5 times that of die steel, and the linear expansion coefficient is only 1/2-1/3 of iron or steel. This characteristic makes it excellent in applications such as heat transfer and heat treatment.

Good corrosion resistance and oxidation resistance
Tungsten alloy has good corrosion resistance and oxidation resistance, which makes it important for applications where long-term exposure to high temperatures or corrosive environments is required.

weldability
High density alloys can be brazed with steel, silver welding materials, and can also be electroplated. This weldability gives it an advantage in situations where connection or repair is required.

Good machining characteristics
Tungsten alloy has good ductility, can be turned, milling, planing, threading and tapping machining, but also can be rolled, rotary forging and forging processing and other large deformation strengthening treatment. This machining characteristic makes it widely used in the manufacturing industry.
