Mass within a defined volume
Counterweight selection starts with target mass, available space and installation geometry.

Counterweight selection starts with target mass, available space and installation geometry.
W–Ni–Fe and W–Ni–Cu have different characteristics. Identify magnetic and process requirements explicitly.
A finished ring, balance part and shielding component require different dimensional and acceptance checks.
| Property / specification | Reference or selection | Procurement meaning |
|---|---|---|
| Material systems | W–Ni–Fe / W–Ni–Cu | Name binder system and material grade |
| Brochure density overview | 16.8–18.6 g/cm³ | General family range; actual grade density requires agreement |
| Magnetic behaviour | Binder-system dependent | Specify any magnetic-permeability requirement and required verification |
| Mechanical properties | Composition and processing dependent | State tensile, ductility or hardness criteria only where needed |
| Component geometry | Drawing-based | Critical mass, centre of gravity, holes, fits and interfaces |
Reference basis: Our product brochure, printed pages 12–13. These values or composition examples describe the material family. They are not guaranteed values for every delivered grade or finished component.

Connect the material choice to the finished component: identify the process, contact surfaces, operating conditions and critical assembly interfaces.
Use the examples below to prepare a drawing-based enquiry. Final material suitability and achievable geometry are reviewed for your project.
Define target mass, mass tolerance, centre-of-gravity requirement and fixing details.
Supply radiation type, equipment layout and an approved shielding design; a material page does not validate attenuation.
Mark fits, contact surfaces, mechanical requirements and the selected alloy condition.
| Order input | Custom scope | What to send |
|---|---|---|
| Material and grade | Plate, rod, blanks, counterweights, rings and drawing-based shielding geometries | Exact grade, standard, chemistry and delivered condition |
| Dimensions and features | Length, width, thickness, diameter or part geometry | Drawing revision, critical tolerances, interfaces and machining allowance |
| Surface and fabrication | Finish, cleaning, cutting or machining requirements | Mark acceptance surfaces, joining details and any permitted process route |
| Duty and documentation | Operating conditions, quantity and required checks | Include material documents, dimensional inspection, destination and requested schedule |
