Casos de estudio sobre minerales críticos y tierras raras

Estos casos de minerales críticos explican cómo EuStrategix ayuda a los fabricantes europeos cuando el tiempo, la pureza y el cumplimiento normativo no son negociables.

Cómo un laboratorio español de fotónica eliminó retrasos de 6 semanas utilizando el modelo de suministro JIT de EuStrategix.

Laboratorio de investigación que suministra componentes ópticos a integradores de defensa y aeroespaciales.

Materiales típicamente requeridos: Ta₂O₅, Nb₂O₅.

El desafío::
El laboratorio enfrentó retrasos críticos cuando los proveedores tradicionales cotizaban plazos de entrega de 4 a 6 semanas para pequeños volúmenes (1–5 kg).

Tuvieron dificultades con:
Pureza inconsistente en envíos de pequeños volúmenes
Documentación de cumplimiento normativo incompleta o inexistente

Delays due to export restrictions:
La necesidad de polvos trazables y conformes con REACH para auditorías.

Estos retrasos estaban obligando al laboratorio a posponer procesos de recubrimiento óptico y ciclos de prototipado, lo que les estaba costando tiempo, credibilidad y oportunidades de financiación..

The EUS Solution:
EUS provided: High-purity Ta₂O₅ and Nb₂O₅ (4N–5N) in 1 kg and 2.5 kg formats.

Documentación totalmente trazable y conforme con REACH. (CoA, SDS, trazabilidad de lote).

Envío desde stock en depósito aduanero en Madrid en un plazo de 72 horas.Etiquetado bilingüe y embalaje preparado para auditorías.

Resultados:
Reducción del plazo de entrega de 5 semanas a 3–4 días.

Trazabilidad completa de cumplimiento normativo: auditoría superada sin ninguna observación.

Los ciclos de producción de I+D óptica se estabilizaron. Ahorro de costes: eliminación de pedidos de emergencia y envíos urgentes (RUSH).

El laboratorio ahora utiliza EUS para compras JIT de pequeños volúmenes de Ta₂O₅ y Nb₂O₅..

Comentarios del cliente
«La fiabilidad de EUS ha transformado la forma en que programamos nuestros procesos de recubrimiento.
Por fin podemos planificar con confianza.»

“How a French Aerospace Supplier Secured Its Supply Chain During a Global Shortage of Nb₂O₅”

A Tier-2 aerospace manufacturing company producing ceramic-based components for propulsion and high-temperature applications.

Materiales típicamente requeridos: Nb₂O₅ (4N+), Ta₂O₅.

El desafío:
During a global tightening of niobium pentoxide supply, the company was exposed to:
–Supplier rationing and no guaranteed delivery windows
-Inconsistent documentation (REACH gaps, missing CoA fields)
-Production slowdowns due to raw material unavailability

Their annual Nb₂O₅ consumption was under 100 kg, which made them a low-priority customer for major traders. The risk was missed delivery deadlines.

The EUS Solution:
-EUS offered: Quarterly JIT delivery from bonded Madrid stock
-Pre-reserved material blocks (no rationing)
–Full documentation package: CoA + MSDS + traceability + compliance letters
-Guaranteed purity: 99.99% (4N) with <3 µm particle size
-Packaging adapted to aerospace cleanroom requirements

EUS created a supply agreement tailored to their small-volume but high-criticality needs.

Resultados
Zero production stoppages during the shortage Improved quality consistency in ceramic firing,
reduced internal compliance workload and the company expanded its EUS orders.

Classified EUS as their “continuity supplier”.

Comentarios del cliente
“EUS gave us what no major supplier would — guaranteed availability, documentation discipline, and delivery we could count on.”

“How a Spanish University Lab Accelerated Materials Research With Reliable Small-Lot Deliveries“

A materials science and photonics research Laboratory with a focus on thin films, optical coatings and quantum materials.

Typical materials required: Ta₂O₅, Nb₂O₅,

El desafío:
The lab’s research depended on unpredictable deliveries from large global distributors. They struggled with: long lead times (5–7 weeks),
difficulty obtaining very small lots (25 g – 100 g),missing documentation for grant compliance and safety checks,needing multiple high-purity oxides from a single supplier
,budget pressure to avoid minimum order quantities (MOQs).

This slowed down student projects, delayed publications, and risked losing competitive EU research funding.

The EUS Solution
EUS delivered: Lots ( 25 g, 50 g, 100 g) with identical purity to production lots,, full documentation: COA, MSDS, traceability, REACH, express JIT shipping from Madrid (typically 72 hours), support letters for safety protocols and grant audits, Stable pricing for 12 months to help with budget planning.

Resultados
Cut procurement time from 6 weeks to under 5 days, enabled a new research line requiring ultra-pure oxides, Improved consistency in thin-film experiments and dielectric measurements, and recognized EUS as a “rapid-response supplier” for critical oxides

”EUS has become essential to our research. The JIT delivery and documentation quality let our students and researchers move at full speed.”
