Microstructure for thermal duty
Oxide dispersion and processing route matter when discussing creep and thermal-cycle requirements.

Oxide dispersion and processing route matter when discussing creep and thermal-cycle requirements.
MoLa and TZM use different strengthening systems. Match the material to the equipment specification.
A rod, wire and furnace part require different dimensional, surface and assembly inputs.
| Property / specification | Reference or selection | Procurement meaning |
|---|---|---|
| Material system | Molybdenum with dispersed lanthanum oxide | Specify oxide content and grade; do not assume a simple metallic La addition |
| Published oxide-content examples | 0.3 or 0.7 wt% La₂O₃ | General material examples, not the complete BOMO grade range |
| Delivered condition | Specified by order | Worked, stress-relieved or other requested state affects the material |
| Density / mechanical values | Grade and condition dependent | Use an agreed grade data sheet or required test report |
| Product dimensions | Drawing-based | Define section size, length, form and critical tolerances |
Reference basis: Published molybdenum-alloy reference. 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 shield, support, fixture or heating-component geometry and the thermal environment.
Specify diameter, length, straightness, delivered state and the finished component role.
Provide load, joining details and atmosphere for a grade-specific review.
| Order input | Custom scope | What to send |
|---|---|---|
| Material and grade | Rod, wire, sheet, plate and drawing-based thermal components | 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 |
