Pure 6061-T6 Aluminum Base (100 kg batch):
- Raw 6061 ingots: $2,000 – $3,000 (depending on supplier purity and form).
- Vacuum purification to remove Cu/Fe impurities: +$800 – $1,200 per batch (equipment rental or contract service).
3% Enriched Lithium-7 Addition:
- High-purity Li-7 powder (99.9%): ~$50/g. For 3% of 100kg, that’s ~3kg Li-7 = $150,000. Note: Commercially available Li-7 is rare; prices may fluctuate wildly based on source and quantity.
0.5% Tungsten Carbide Particles:
- WC powder (<5µm particle size): ~$200/kg in bulk quantities for industrial use. For 0.5kg in a 100kg mix = $100 – but sourcing ultra-fine WC specifically could be higher ($500-$1,000/kg).
0.2% Samarium Addition:
- Sm metal powder (~99% pure): ~$120/g in small quantities; large orders might reduce this to ~$80/g for bulk purchases over 10kg (e.g., Alibaba quotes). For a 0.2kg addition = ~$9,600 to $14,400.
Casting Process & Ultrasonic Cavitation Equipment Rental:
- Custom ceramic molds (per piece): Could range from $500-$5,000 depending on complexity and material quality.
- Argon gas flow setup rental (day rate): Assume $800-$2,000/day.
- Ultrasonic cavitation equipment rental or purchase: A basic lab setup could be rented at ~$500/day or purchased used for <10k.
Solution Heat Treatment & Cryogenic Quenching:
- Furnace time rental: Assume $300-$600/day.
- Liquid nitrogen (~50L needed for quenching): Bulk LN2 costs around $0.50/L; thus ~$25 plus delivery/setup fees.
Aging Cycle & Thermal Shock Conditioning:
- Specialized oven capable of precise temperature cycling + compressed air jets for rapid cooling: If custom-built or modified from existing equipment, estimate >$20k capital investment.
Final Machining & Silver Coating:
- CNC machining services per part hour rate (~$75/hour) depending on complexity and volume.
- Silver electroplating bath chemicals + labor estimate ($300-$900 per batch).
- Total Estimated Cost*: For a single prototype batch of Mondaloy (~100 kg), expect costs between ~$250k to ~$450k, largely driven by the exotic nature of enriched lithium and samarium additions along with specialized processing steps requiring high-end equipment rentals/purchases.
