Application:
Ball valve and Bearing shotshell reloading,tss turkey loads,hunting sphere, hunting sphere ,counterweightfishing sinker
1. Producing ion implantation parts
2. Producing electric light source parts and electric vacuum components
3. Making heating elements and refractory parts in high temperature furnaces
4. Used as electrodes in the field of rare earth metal industry
Advantages:
1. Tungsten alloy sphere is very dense and small in volume, which means it can be used in fields requiring small but heavy parts.
2. Counterweights in golf clubs, fishing weights, counterweights for military defense,equipment, counterweights, prefabricated fragments, oil logging.
3. Also some fields in precision industry, such as mobile phone vibrator, clock cube, self-winding watches, anti-vibration toll holders, flywheel weihts, etc.
4. The density allows it fly long distances without slowing down, while the hardness allows it to keep their shape while being accelerated by the powder charge, which increases the muzzle velocity.
5 Heat resistance
The melting point of tungsten is 3422 degrees Celsius, And the melting point of iron is only about 1500 degrees Celsius
6 Hard
When tungsten combines with carbon, will become very hard. The hardness is close to the diamond.
7. High density
The density of tungsten is almost the same with gold. Advantages of tungsten alloy fishing weights/sinkers
