巴基斯坦采购需求：电火花加工丝、钻夹头、伽玛丝、电极管、铜钨丝、电火花加工黄铜丝

I'm looking for information on Chang Heng Moli wire. Could you please provide detailed specifications and available options? I'm particularly interested in different gauges, materials, and any unique features that might be available. In addition, it would be great to know your pricing structure, minimum order quantities, and lead times for delivery. If there are any sample options or catalogs, please include those as well. This will help me assess how to integrate this wire into our upcoming projects. Thanks!
