The Top 10 Reasons Why Tungsten Is Better Than Lead

1. Environmentally Friendly
Tungsten is much more environmentally friendly than lead. In fact, according to the U.S. Government's Priority List of Hazardous Substances, lead is the second most hazardous substance (Arsenic being #1).

2. Higher Density
Lead has a density of about 10 g/cc, but with tungsten, you can achieve densities of up to 18.6 g/cc! Higher density means smaller parts for the same weight.

3. Non-Toxic Alternative
Lead has already been phased out of kids’ toys, electronics, and electrical equipment. New regulations for lead paint removal go into effect in April 2010. At some point all lead use will be phased out, so why not get a jump on finding environmentally-friendly lead alternatives, like tungsten?

4. Hardness
Tungsten comes in many alloys, from a machinable alloy to a diamond-hard one. The alloy can be tailored to each specific application. Wear resistance and heat resistance are just two of hundreds of suitable applications.

5. Highest Melting Point
Despite its incredible hardness, tungsten can still be melted. However, at 6170°F (3410°C), tungsten has the highest melting point of any metal.

6. Versatility
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 (flywheels, cases, dies, rods, plates)
c.Jewelry (rings, bracelets)
d.Radiation Shielding (the protective mats radiologists use when taking your x-rays)
e.Sport (darts, golf clubs, fishing weights and lures)
f.Stationery (the tips used in ballpoint pens)
g.Weights (balance weights, wheel weights)

7. Cheap Disposal
Since Tungsten is environmentally friendly, there, are no federally mandated disposal costs associated with getting rid of tungsten, as there are with lead.

8. Recyclable
Tungsten parts are manufactured from powder using a powder metallurgy process. This allows each tungsten part to be recycled back to its original powder form. The recycling cost is relatively small and the process is well known and available in every country. There is a very small loss in tungsten recycling.

9. Highly Corrosion Resistant
Like lead, tungsten has excellent corrosion resistance, and is only attacked slightly by most mineral acids.

10. Appearance
Tungsten alloys can be plated and polished, thereby offering a wide variety of finishes.
