Lead vs Tungsten

Lead and Tungsten are genuine alternatives to one another — a choice somebody actually makes — and differ on 6 measured properties, density most clearly.

Lead vs Tungsten

Lead

Pb

Soft, dense, easily worked, and quietly poisoning people for three thousand years.

Tungsten

W

The highest melting point of any metal, which is why lightbulb filaments were made of it and why it is used to drill through everything else.

Choosing between them

Tungsten is recorded as a substitute for Leadless toxic.

What it gives up: Denser and far harder to form, and many times the price for a property lead had for nothing.

In this application, on the evidence cited above.
