1kg Tungsten Bar Price

Tungsten bar/rod is mainly used to found ingredient of material, cutter and heads, 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. Also used for making special steels, to make guns, artillery rockets, satellite airplane and ship. Tungsten bars have a luster rather like that of silver in uniform color. Though the whole tungsten bars may slightly curve, the maximum height of the bend should not be more than 7mm. The most popular application of tungsten bar is in steel making industry. Tungsten bars are used to improve the property of steel.
Tungsten bar with impurities is used to procedure bulb filaments or electron tube filaments, which are guaranteed to have remarkable resistance to high temperature.

Our Service

LASER & WATER JET CUTTING

Both processes are relatively quick, but are not suitable for parts with tight dimensional tolerances. For parts with high tolerances, we suggest EDM cutting.

GRINDING

As tungsten is difficult to conventionally machine, grinding is often used to manufacture parts with tight tolerances or fine surface finish requirements.

WINDING

Our current capabilities include the winding of not only evaporation filaments, but also of electron beam and ion beam filaments.

SHEARING, PUNCHING, & STAMPING

In addition to numerous stamping and forming presses, brakes and shears, we also has CNC punches and tack welding equipment to form refractory metal sheet into the products that you need.

Nitinol Shape Memory Alloys undergo a phase transformation in their crystal structure when cooled from the stronger,
high temperature from (Austenite) to the weaker, low temperature from (Martensite). This inherent phase transformation is the basis for the unique properties of these alloys - in particular, Shape Memory and Superelasticity.
