Applied parts

Used as the evaporation source in vacuum coaters, the melting crucible in high-temperature furnaces and the vessel in crystal growth equipment. Material and shape are designed around what it will hold and at what temperature.

KEY FEATURES

Putting large mass into a small space

Far heavier than lead at the same volume.

Its high density puts the same mass into a smaller volume.

High density

High Density

17 – 18.5 g/cm³. It secures the mass and shielding needed even in a confined space.

Machinability

Easier to machine than pure tungsten, so complex non-standard geometries are possible.

Non-toxic

Lead-Free

It replaces lead, reducing the handling and disposal burden.

Density by material

Tungsten heavy alloy18.5

Lead (Pb)11.3

Iron (Fe)7.9

Density g/cm³. The higher the figure, the heavier at the same volume.

Why heavy alloy

Pure tungsten is hard and difficult to machine. Heavy alloy keeps the density while being easy to machine.

Balance design

In a counterweight, the position of the center of gravity matters as much as the mass. Geometry is what sets it.

DESIGN PRECISION

Geometry set to the mass required

In shielding, density and geometry are what distinguish the product.

At the same mass, changing the geometry and composition changes the volume and the center of gravity.

Densitychoice

Composition

Chosen between 17 and 18.5 g/cm³ together with machinability.

Drawingbasis

Machined geometry

We look at the mounting space and the center of gravity together.

Platingor paint

Surface treatment

Set by the corrosion and contamination conditions.

We do not pick a specification, we develop it with you. (Give us the required mass and the mounting space, and we will work out the geometry with you.)
