Mo ALLOYS · MASTER ALLOYS · CUSTOM COMPOSITIONS
Compare Mo–Cu, Mo–Ta, Mo–Nb, Mo–Ni and other listed compositions. Define the alloy chemistry, product form and condition for your component. Alloy composition takes the place of a generic pure-molybdenum purity claim.

Mo–Cu catalogue example.
The original product views below illustrate selected material families. Use the composition table to identify the requested grade; photographs do not establish chemistry, condition or tested properties.

Review the listed 90Mo10Nb or 95Mo5Nb compositions, ingot dimensions and required material condition.

Specify the required full chemistry, composition basis, form and quantity for the master-alloy enquiry.

Define the Hf/C composition, sheet, plate, rod or bar dimensions, material condition and inspection requirements.

Provide the Zr/Hf/C composition, product form, finished dimensions and required material condition.
The catalogue labels and ranges below are references for an enquiry. State whether composition is wt% or at%, define element tolerances and impurity limits, and identify the required certificate or test basis.
| Material family | Listed composition and supply references |
|---|---|
| Mo–Cu | Listed grade labels: Mo15Cu, Mo20Cu, Mo25Cu. Custom shapes are listed. Confirm the complete Mo/Cu fractions and composition basis; the labels alone do not define the order. |
| Mo–Ta | Listed range: Mo 99%–92.5%, Ta 1%–7.5%. Confirm the selected composition, reporting basis and product form. |
| Mo–Nb | 90Mo10Nb or 95Mo5Nb; ingot form. Density reference: 9.2–9.4 g/cm³. |
| Mo–Ni master alloy | Listed reference: 50Mo50Ni (47%–51%); the source also mentions Al and Si. Density reference: 9.2 g/cm³. Melting-point reference: 1,560°C. Confirm which component the 47%–51% range describes, full chemistry and material condition. |
| Mo–Cr | Molybdenum with chromium. The catalogue does not define a numerical composition; provide the required grade or chemistry. |
| Mo–Si | Molybdenum with silicon. Define the composition and material specification; this listing does not by itself identify a particular silicide formula. |
| Mo–Ti / Ti–Mo | 80Mo20Ti, 90Mo10Ti or 84Ti16Mo. Listed powder ranges: 0–45 µm and 0–150 µm. Confirm the base material, composition basis and particle-size specification. |
| MHC | Mo–(0.8–1.4%)Hf–(0.05–0.15%)C. Listed forms: sheet, plate, rod, bar or custom geometry. |
| MLR | Molybdenum, lanthanum and rhenium. Define the element fractions, material condition and product form for the requested composition. |
| ZHM | Mo–(0.4–0.7%)Zr–(1.2–2.1%)Hf–(0.15–0.27%)C. Listed forms: sheet, plate, rod, bar or custom geometry. |
Density and melting-point entries are material references, not finished-part service limits or batch measurements. Confirm the offered composition, material condition and documents. A Mo–Si material is not automatically MoSi₂, and a Ti-rich Ti–Mo composition must not be described using pure-Mo specifications.
Send the required composition, product form, condition, dimensions and quantity. Where the catalogue gives no element fractions, a grade name alone is insufficient to define the order.
The catalogue also names Al–Mo, Fe–Mo, Al–Mo–V–Ti and Al–Mo–V–Fe master alloys and semi-finished products. Specify the full chemistry, form and intended use. For the listed Mo–Ti powders, define the particle-size requirement as well.
The Mo–Cu catalogue context includes vacuum contacts, conductive heat-dissipation and instrumentation parts, sealing or contact components, and electrode-related geometries. Provide the actual thermal/electrical requirements, service conditions, geometry and joining details.
The MHC and ZHM listings discuss tooling and forging-die uses; MHC also names vacuum-furnace and rotating-anode target applications. Define temperature, load, dwell, atmosphere, material condition and acceptance criteria for the proposed component.
Other catalogue contexts include flat-panel displays, semiconductor equipment, aerospace and nuclear-related components. Identify the actual material, composition, form and application-specific documentation. Catalogue application names do not establish certification or universal suitability.
Comparative conductivity, strength, creep, corrosion or recrystallization claims depend on composition, processing, condition and test conditions. State the performance data and acceptance evidence required for your application.
Provide the full Mo/Cu fractions, reporting basis and allowed tolerances. The listed grade labels are not interpreted here as a confirmed weight or atomic composition.
An alloy requires its own element fractions and impurity limits. Define the complete material specification and condition rather than applying an unalloyed-molybdenum purity value to Mo–Cu, MHC, ZHM or another composition.
Send the proposed chemistry, form, dimensions, quantity and intended application for review. Availability, material condition and required inspection documents are confirmed for the requested configuration.
State the full chemistry and composition basis, form or particle-size requirement, quantity, impurity limits, intended processing route and required documents. A listed size range does not establish a measured particle-size distribution for an offered lot.
Review a separate Mo–W material family and specify the selected composition and form.
Review Mo–Re product forms and composition-specific enquiry requirements.
Review the separately defined Mo–La material family and required product condition.
Background on molybdenum and alloy naming before specifying chemistry, form and condition.
Application context for refractory-metal alloys and components used in a furnace or crystal-growth assembly.
Alloy products are tagged and externally labelled for identification. Confirm the packing arrangement, material identification, surface protection and inspection records for the selected form and delivery.
Send the full composition and basis, product form, condition, dimensions, quantity and application requirements. Add the inspection documents and delivery details needed for the order.
