越南采购需求：钛粉、碳化钨粉、铋锭、钨钴粉、铋粉、二硫化钼

I'm looking to find a reliable supplier for Titan powder based in Vietnam. Our company is considering expanding our product line, and Titan powder is a key ingredient we are interested in sourcing. It would be great to know if you have any connections or recommendations for sellers who can provide this material consistently and at a competitive price. In addition, I would appreciate any information regarding minimum order quantities, lead times, and whether you have experience working with any specific suppliers in the region. If you could provide some insights or referral options, that'd be super helpful as we navigate this procurement process. Thank you!
