埃及采购需求：钼靶、钼带、钼箔、钼桶、钨粉、钨丝

I am reaching out to procure tubes made from pure tungsten. The specifications I'm looking for include an outer diameter of 3 mm and a length of 30 mm, with a wall thickness of 0.5 mm. It's crucial that the material is high-purity tungsten to ensure optimal performance for my application. Could you please provide details on availability, pricing, and lead times for these tubes? Additionally, if you have any recommendations regarding manufacturing processes or quality certifications, I would be interested to hear them. Looking forward to your prompt response so we can move forward with this potential order.
