Since Tungsten is environmentally friendly, there, are no federally mandated disposal costs associated with getting rid of tungsten, as there are with lead as it is known to all that lead interferes with the development of the nervous system and is therefore particularly toxic to children, causing potentially permanent learning and behavior disorders.

As a matter of fact, industrial scrap (new scrap) and used scrap (old scrap) are recyclable, so it does not need much effect to dispose tungsten. For example, in 2000, an estimated 46 percent of U.S tungsten supply was derived from scrap. The ratio of tungsten consumed from new scrap to that from old scrap was estimated to be 20:80.

Tungsten has the highest melting point of any pure metal at 6170°F (3410°C), while lead melted at 621.43 °F (327.46 °C), which make tungsten rod of value in a variety of high temperature products and processes. Among them are glass-to-metal seal parts and support parts for lighting and electronics, silicon rectifier stud mounts and high temperature furnace components.

Due to its high density and high melting point, tungsten is as versatile as lead, if not more so. Tungsten can be used as a lead replacement for a variety of applications:

a)        Ammunition (tungsten shot)

,

b)        Industrial (tungsten flywheels, tungsten cases, tungsten dies, tungsten rods, tungsten plates)

c)        tungsten Jewelry (tungsten rings, tungsten bracelets)

d)       Radiation Shielding (the protective mats radiologists use when taking your x-rays)

e)        Sport (tungsten darts, tungsten golf clubs, tungsten fishing weights and tungsten lures) 

f)         Stationery (the tungsten tips used in ballpoint pens)

g)        Weights (tungsten balance weights, tungsten wheel weights)

Tungsten comes in many alloys from a machinable alloy to a diamond-hard one. The alloy can be tailored to each specific application. The hardness and density of tungsten are applied in obtaining heavy metal alloys. A good example is high speed steel, which can contain as much as 18% tungsten. Tungsten's high melting point makes tungsten a good material for applications like rocket nozzles, for example in the UGM-27 Polaris submarine-launched ballistic missile. Superalloys containing tungsten are used in turbine blades and wear-resistant parts and coatings.

Tungsten Carbide is the choice to provide the best protection available for extreme wear and impact. It wears up to 100 times longer than steel in conditions including abrasion, erosion and galling. Wear resistance of tungsten carbide is better than that of wear-resistance tool steels. Wear resistance and heat resistance are just two of hundreds of suitable applications. It can offer wear life in excess of 5 times that of alumina ceramic and has ability for continuous operation a temperatures up to 900 degrees F (480 C). It can also be machined to very tight tolerances and to fine surface finishes as needed. WC is used to make wear-resistant abrasives and cutters and knives for drills, circular saws, milling and turning tools used by the metalworking, woodworking, mining, petroleum and construction industries and accounts for about 60% of current tungsten consumption. The jewelry industry makes rings of sintered tungsten carbide, tungsten carbide/metal composites, and also metallic tungsten. Because of tungsten carbide's hardness, rings made of this material are extremely abrasion resistant, and will hold a burnished finish longer than rings made of metallic tungsten.
