Ground Forged Tungsten Bar Introduction

Details: Category: Tungsten Information; Published on Thursday, 25 September 2014 15:09; Written by jwy; Hits: 593

Ground forged tungsten bar is tungsten bar manufactured through the process of forging and finished by grounding. Tungsten bar is normally recognized as round and rectangle shape. Here is to show the rectangle tungsten bar, with the bright, smooth and ground surface. The purity of tungsten bar is over 99.95% and the density is over 19.0g/cm3. The surface roughness is Ra3.2um. Ground forged tungsten bar can be used for manufacturing tungsten sheet or tungsten plate. More detail, please visit ground forged tungsten bar.

What are tungsten bar and its application? Tungsten bar includes tungsten rod, tungsten steel bar, tungsten sintered bars and more.

Ground tungsten bar is mainly used to found ingredient of material, cutter and head, tungsten wire for lights instruments, electric contact points and conductor of heat, crankshaft and cylinder barrel of advanced automobile, ingredient of kinds of heat-resistant steel.The process of grounding is centerless ground the surface to remove all coating and to achieve precise dimension control.

Tungsten Rod Categories

Tungsten rod can be divided into two categories: one is for finished tungsten rod bar. The other is for drawing wire semi-finished rough rod material. It has two processing ways: spinning machining and holes rolled. We own exquisite machining techniques. The tungsten rod bar we produce has good characteristics of extremely strong electrodes, high temperature of oxidation resistance, long service life and corrosion resistance.

Tungsten rod can be made into tungsten wire. Due to the big hardness of tungsten, small mechanical abrasion and refractoriness, so tungsten material is widely used for electric connected touch for mobile motor distributor, voltage regulator of automobile engine and electric system. In addition, tungsten rod bar can be supplied for electrodes, electric tube bars, side bar, quoted line, gas lamp electrodes, high efficient incandescent filament, filament tube, launched tube cathode, senior automotive crankshafts and so on.

Swaged Tungsten Rod

Swaged tungsten rod is made through constant swaging. After centerless grinding, surface diameter’s completeness and accuracy have improved. They can be machined into various shapes, but the most common shape is cylinder. The tensile strength of tungsten rod bar has promoted 1050MPa to 1200Mpa after swaged. Swaged tungsten rod bar is made by forging and sintering tungsten block.

Tungsten support rod

Tungsten support rod has a better function as a bearing component in vacuum furnace such as thermal property, mechanical stability, configuration and service life. In the meantime, tungsten support rod can be made into all kinds of styles. Comparatively speaking, tungsten support rod is the best choice for excellent high temperature application. Tungsten support rod has provided superior mechanical properties and tensile strength.

Sintered Tungsten Rod

Sintered tungsten rod bar is always used for vacuum high temperature furnace such as sapphire single crystal furnace. Sintered tungsten rod bar’s density is 18.3 g/cm3. Basically it is close to tungsten theory density. They are high temperature resistance. Sintered tungsten rod bar’s melting points can reach 3380℃. They also have characteristic of creep resistance.

Tungsten Worm Weights 2

To peg basic worm weights just use a toothpick or a specially designed peg. An alternative is buying weights with screws or hooks to fasten the weight to the plastic.

Tungsten worm weights are perfect for any presentation. The high density of tungsten which makes diameters of tungsten worm weights smaller, allowing them to slip through snags much more easily than lead.

Tungsten worm weights have great sensitivity about the bottom. When you drag tungsten worm weights along the bottom, you'll be able to distinguish between bottom compositions, such as sand, gravel, rock, mud, and wood.

Tungsten Rod for Counterweight and Semiconductor

Details: Category: Tungsten Information; Published on Wednesday, 24 September 2014 15:18; Written by jwy; Hits: 581

Tungsten rod is a basic part for manufacture of a probe pin. It should not have defectiveness in straightness and in cut surface. A probe pine is the core part of a probe card which is inspection equipment. The probe pin is produced through chemical etching manufacturing process and mechanical manufacturing process. The probe card connects at the same time each signal wires of a tester with each pad of a wafer by chip unit so that a wafer tester can really test the function and capacity of a wafer.

Kind of Tungsten rod for semiconductor:

Raw tungsten + wire plated by Ni

Raw tungsten (Not plated by Ni)

General tungsten + wire plated by Ni

Tungsten guide rods offer the ultimate in recoil reduction. Tungsten weighs more than double
