High Precision Molybdenum Wire Product Details – Empowering Precision Manufacturing
Product Overview: What is Molybdenum Wire?
Molybdenum Wire is a wire product made from high-purity molybdenum metal (purity ≥99.95%) through precision wire drawing processes. Leveraging molybdenum’s inherent properties—high melting point (2620°C), exceptional tensile strength (≥2000 MPa), and low thermal expansion coefficient—molybdenum wire delivers outstanding performance in high-temperature, high-pressure, and high-precision applications. As a core consumable in Electrical Discharge Machining (EDM), EDM Molybdenum Wire (specialized for EDM) has become the preferred material in high-end manufacturing sectors such as precision molds, aerospace components, and medical devices, thanks to its conductivity, corrosion resistance, and dimensional stability.
Core Advantages: Why Choose Our Molybdenum Wire (Moly Wire)?

FAQs
Q1: Key differences between Molybdenum Wire and brass wire?
A1: Molybdenum wire has a higher melting point (2620°C vs. 1083°C) and 2–3x greater tensile strength, making it ideal for high-precision and hard-to-machine materials.
Q2: How to store Mo EDM Wire for extended lifespan?
A2: Store in sealed packaging at <60% humidity and 15–25°C. Use within 6 months after opening.
Q3: Common causes of frequent wire breaks during machining?
A3: ① Incorrect tension settings (recommended: 8–15N) ② Coolant conductivity exceeding limits (maintain 15–50μS/cm) ③ Moisture exposure during storage.

At first we will make sure that we got all customer's requirements clear. Then place order to production department and inspection department. Each production process will test themselves if everything is right. And before shipping, all products will pass the packing department only after inspection department inspected that the products meet customer's requirements. If not, the products will go back to production department for fixing or remaking.
For production, normally our lead time is 20-30 days. But according to different products and different quantity, it changes a little. If your order is emergency, contact with us, we will find a way out to solve your problem. For shipping, normally we ship by express and air. Express takes about 7-10 days, and air 3-5 days. And if customer requires by sea, we will ship by sea, it takes normally 40-50 days.
All our products are shipped after strict inspection and safety packing. Inspection by each production process makes sure the quality is good. And the inspection department will inspect again carefully to make sure everything is right. But if quality issue really occurs, we are sorry, and we will be responsible. To fix the products or remake them, we will make everything right.
In order to keep our healthy cooperation, our payment term normally is 50% payment in advance, balance paid before shipping. And if customer needs, we will calculate the shipping cost for your reference.
