Tungsten is alloyed with steel to form tough metals that are stable at high temperatures. Tungsten-steel alloys are used to make such things as high speed cutting tools and rocket engine nozzles. Tungsten carbide (WC) is an extremely hard tungsten compound. It is used in the tips of drill bits, high speed cutting tools and in mining machinery.

2009年2月22日 · IANAL but tungsten cores machined to a point would almost certainly qualify as armor piercing and be subject to existing restrictions on manufacture. However bullets with tungsten powder cores or solid-slug cores (i.e., a flat-faced tungsten cylinder) should not pose a risk of such classification or regulation.

The tungsten trioxide is then heated with either carbon or hydrogen gas to form the pure metal. This is the reaction if tungsten trioxide is heated with carbon: 2WO 3 + 3C + heat → 2W + 3CO 2 (tungsten trioxide combines with carbon to form tungsten metal and carbon dioxide) This is the reaction if tungsten trioxide is heated with hydrogen gas:

The Element Tungsten - Known Isotopes. Most of the isotope data on this site has been obtained from the National Nuclear Data Center.

2023年10月14日 · I have a basically new (under 40 rounds fired) kkm 4.6 barrel. It fits the factory Glock slide. I also have heavy pure tungsten guide rod with the uncaptured 20 lb spring from the Glock store. I want $125 for the barrel and $100 for the spring. Will also throw in a gunfighters inc Kenia chest holster for free if interested.

2023年11月27日 · So I got ambitious and custom ordered a tungsten weight kit for my Foundation Genesis MG2 stock. I was considering the lead or brass weight kit options out there but when I looked into the density and weight of tungsten (almost double the weight of lead/brass) I decided to go for it and custom...

Rhenium is used in flash lamps for photography and for filaments in mass spectrographs and ion gages, but is most frequently used as an alloying agent in tungsten and molybdenum and as a catalyst for performing certain reactions to a type of hydrocarbon known as an olefin.

I only use tungsten-core bullets made by Powell River Labs and now Dynamic Research Technologies. I just wanted to illustrate the terminal performance of tungsten-core bullets. The bullet, a 200gr .308 was loaded to 2900ft/sec in a .300WM case. The mule deer in the picture was hit once with the...

2023年4月26日 · Selling my Barrett MRAD SMR (Tungsten Grey) in 300 Win Mag for $3500. $3200 Bought this a few years ago and never took it out of the safe. Needs to get to someone who will put it to good use. Other than testing at the factory, this gun has never been fired. Comes with everything shown. Can...

2025年1月9日 · I have a left hand Foundation MG2. Comes with Foundation full length Arca rail, Hawkins M5 DBM, Weibad cheek pad, and full Tungsten weight kit. This was originally inletted for a Vudoo but has since been made to fit a Deviant Defiance. I will not separate this kit unless the stock sells first. Only trades would be an MCS-TCS or a Greyboe ...
