蒙古采购需求：铝、铜、铝系列及制品

I'm looking to purchase copper and would appreciate more details on the available products you offer. Specifically, I'm interested in the grades, forms, and any additional specifications you can provide. Also, if you have current pricing and minimum order quantities, that info would be really helpful. Additionally, it would be great to understand your lead times and shipping options, as I have a project timeline to consider. If you could send over a catalog or a product list, that'd be awesome. Looking forward to your prompt response so we can discuss this further.
