Tungsten bar has the highest melting point of any metal of approximately 3422 degrees Celsius, but with the lowest vapor pressure. Especially, tungsten bar has very high densitys, high temperature resistance, non-toxic, etc .
Density:≥19.20 g/cm³
Purity:≥99.95%
Surface condition:black-faced ,polished sruface
Appearance of tungsten bar: The appearance of tungsten bar turns to be metallically gray or dark gray. Hygroscopy is not allowed on the appearance of W1 ,W2, and W3 tungsten bars.
Tungsten bars stock are manufactured from high purity tungsten powder. Because of the special properties of tungsten, these rods and bars have many applications such as welding electrodes and electrical contacts.

Tungsten bar includes tungsten rod, tungsten steel bar, tungsten rod, tungsten sintered bars and more, which 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.
Tungsten bar with impurities is used to produce bulb filaments or electron tube filaments, which are guaranteed to have remarkable resistance to high temperature. Tungsten is a naturally occurring metal mined from the earth. In this raw form, tungsten can be very brittle. In general, tungsten bar can be divided into three types.

Tungsten flipping weight have smooth curved edges with shape of a cross between a bullet and a little ball, so that the line can't snap on high impact hook sets. Flipping weights feature for insert-free technology, so that you don't have to use toothpicks.
Tungsten flipping weight are very sensitive, you can feel even little tick of the bottom and you can even feel the bottom soft or hard .The weights come in sliding and screw in versions as well.
Tungsten flipping weight are perfect for any type of Texas or Carolina rig application. Tungsten flipping weight are great for punching through heavy cover and are available in both natural and black colors.
