Tungsten has magnetic properties,but not like you'd think.Tungsten is paramagnetic.It doesn't produce a magnetic field.Actually,
its the perfect meterial for a watch case.While steels can become magnetised.tungston orients towards the magnetic field,but when the field
is gone,tungsten doesn't retain the magnetism.Basically,tunsten doesn't attract the field like steel does.
Tungsten in its raw form is heavy and brittle.Has a dull gray appearance.In its purest form,its easier to work than most steels.
It can be worked by forging,exruding and sintering.It also has the highest melting point.
Tungsten in its purest form can be cut with a hacksaw.Thats counter to what I've heard about this material.
But when combined in small amounts to other alloys,like steel,the steel can take on super hard properties.Mainly a military metal used
in missiles for bunker busting.
So when used for watch cases,it can have any color or finish you require.Rado has been using it for years.
But if the tungsten isn't pure when shaped,it can scratch.You all remember some of the swiss legend tungsten watches where
the bracelets scratched.This also happened to invicta. using poorly made tungsten to save afew bucks will always bite you in the ass later.
Invictas excuse was that colored tungsten wasn't as hard as pure tungsten.Thats not correct.Makes for a good myth though.
I think using tungsten carbide as a coating on steel is a much better solution.You get the hardness of tungsten with the lighter weight of steel.
Seiko and Citizen use this coating process on some steel and titanium watches with great success, even though they call it by another name,
its still a tungsten coated product.
I'd ask Chris from DWC about the chemical makeup of this.He works in this field.
