I'm currently looking to purchase a specific type of high-purity ingots, specifically 100 kg worth. I would like to understand your pricing for these products, taking into consideration any bulk purchase discounts or special offers that may apply. Additionally, it would be helpful if you could provide information regarding the lead time for delivery, payment terms, and any minimum order quantities I should be aware of. If you have any relevant specifications or certifications for these ingots, please share those as well. Looking forward to your detailed response!
