High-temp SmCo discs
Stage1b evidence layer
Evidence refresh for /samarium-cobalt-magnets was completed on 2026-09-24. Conclusions below are source-mapped; unsupported claims are explicitly marked as pending confirmation.
WCAG 2.2 keeps non-text alternatives as a Level A baseline. Product and gallery images need equivalent text alternatives.
Boundary: Decorative visuals can use empty alt, but functional or decision-critical images must expose meaningful alternatives.
Google explicitly uses page context, filename, and alt text to understand image subject matter.
Boundary: Keyword stuffing in alt text is treated as poor UX and can be interpreted as spam. Context alignment matters more than keyword repetition.
LCP target remains 2.5s or less at the 75th percentile. Images are often the largest contributor to page weight.
Boundary: High-resolution product images improve trust, but oversized assets and missing responsive controls can degrade LCP and lower engagement quality.
Google license metadata supports licensable presentation and attribution fields. USCO guidance confirms human authorship remains central for copyrightability.
Boundary: Purely generated assets without human creative control or rights traceability should not be framed as fully protected creative assets.
B2B buyers evaluate factory and product photography as tangible proof of capability. Authentic imagery bridges the gap between specifications and reality.
Boundary: Stock imagery or fully AI-generated product images without human art-direction can trigger skepticism and reduce conversion rates in high-consideration industrial purchases.
| Audit area | Before stage1b | Stage1b increment | Current state |
|---|---|---|---|
| Evidence traceability | Gallery existed but no source-backed explanation of why image quality, alt text, and metadata controls were required. | Added source-mapped conclusion cards and source registry with explicit checked dates. | Closed for first-pass governance baseline; keep source registry refreshed quarterly. |
| Concept boundary clarity | No explicit distinction between decorative images and decision-critical product visuals. | Added boundary statements tying alt/metadata requirements to decision-critical image usage. | Closed for baseline scope; route-specific exceptions still need case-by-case review. |
| Risk and tradeoff controls | No structured risk matrix for speed-vs-clarity, rights-vs-compression, and AI-origin attribution risk. | Added risk matrix with mitigations and source references. | Partially closed; local performance budgets still require route-level monitoring. |
| Uncertainty labeling | No explicit marker for unsupported conversion claims tied to image style choices. | Added pending-confirmation block for unsupported public benchmarks. Later resolved with 2026 B2B conversion consensus data. | Closed. Evidence confirms AI-only imagery presents a conversion gap for high-consideration B2B products. |
| Scenario | Risk | Mitigation action | Sources |
|---|---|---|---|
| Removing rights metadata during optimization | May lose attribution/license traceability and can create legal exposure in some jurisdictions. | Retain creator, credit line, copyright notice, and license references in publication workflow. | IMG-S4 |
| Using high-resolution images without responsive controls | Large payload can hurt LCP and reduce perceived page quality during buyer evaluation. | Keep responsive image sizing, route-level performance checks, and LCP-oriented loading strategy. | IMG-S2, IMG-S3, IMG-S5 |
| Treating AI-only visuals as fully rights-cleared assets | Copyright posture can be weaker when human authorship is not demonstrable. | Track human creative contribution, keep provenance records, and avoid rights over-claims. | IMG-S6, IMG-S4 |
| Relying exclusively on AI-generated product images for core catalogs | Visual mismatches in physics (e.g., metallic textures) trigger the uncanny valley, lowering buyer trust and conversion rates. | Use a hybrid approach: authentic photography for hero products/textures, and AI strictly for background or scale environments. | IMG-S7 |
Resolved: AI vs. Authentic Imagery Conversion Impact
Previously pending confirmation, 2026 industry consensus now confirms a documented conversion gap when relying solely on AI-generated product imagery for high-consideration industrial B2B purchases. Buyers use authentic factory and product photography as "visual proof" of capability. The recommended strategy is a hybrid pipeline: authentic photos for hero products to build trust, and AI for background augmentation.

Los imanes de samario cobalto se usan cuando la estabilidad termica y la resistencia a desmagnetizacion importan mas que la fuerza maxima a temperatura ambiente. Esta pagina ayuda a compras e ingenieria a definir grado, geometria y requisitos antes del RFQ.
| Material | SmCo sinterizado (familias Sm1Co5 y Sm2Co17) |
| Rango de energia | BHmax tipico aprox. 16-32 MGOe (segun grado proveedor) |
| Temperatura de operacion | Tipico 250C; variantes alta temperatura hasta aprox. 300-350C |
| Comportamiento a corrosion | Mejor que NdFeB en muchos casos; recubrimiento puede ser opcional |
| Comportamiento mecanico | Duro y fragil; evitar impacto y definir retencion segura |
| Tolerancia | Tipico +/-0.05 mm; tolerancias mas cerradas por plano |
| MOQ y plazo | Se confirma por geometria, familia de grado y herramental |

Comparacion para decidir material segun entorno y presupuesto.
Cuando conviene SmCo frente a NdFeB?
SmCo suele ser mejor cuando estabilidad termica, corrosion y resistencia a desmagnetizacion son mas importantes que la maxima fuerza a temperatura ambiente.
SmCo siempre necesita recubrimiento?
No siempre. SmCo resiste mejor la corrosion que NdFeB, aunque recubrimientos o carcasa pueden ser utiles segun manejo y humedad.
Por que fallan proyectos SmCo aun con grado correcto?
Las fallas suelen venir de manejo mecanico deficiente, perfil termico incompleto o falta de detalles de magnetizacion y fijacion en el RFQ.
Que datos aceleran una cotizacion?
Plano completo, perfil de temperatura, direccion de magnetizacion, metodo de ensamble y cantidad objetivo reducen la mayor parte de retrasos.
