Black molybdenum wire Φ0.7mm (pure molybdenum black wire)
Black molybdenum wire is molybdenum wire that has retained the surface graphite lubricating layer after drawing. The surface of the molybdenum wire retains a black appearance, and its cost is lower than washed-white molybdenum wire. The melting point of the molybdenum wire is 2620℃. The product is suitable for applications such as high-temperature, spraying, high-temperature furnace brackets, and heating elements.

0.7mm Black Molybdenum Wire Main Applications
1.The Main Application Of 0.7mm Black Molybdenum Wire Is In The Hot Spraying Industry, Especially The 0.7mm Diameter Is A Common Specification For Hot Spraying
Arc spraying molybdenum wire, sprayed onto automotive piston rings, transmission synchronizers, and wear-resistant parts of construction machinery, forming a wear-resistant self-lubricating coating, improving the wear life of components.
2.High-temperature industrial furnaces, vacuum furnaces
It is mainly used as heating wires, heating elements, material rack hooks, high-temperature support brackets, and molybdenum wire mesh weaving. It can withstand 1000-1800℃ high temperatures for a long time in vacuum / protective atmosphere.
3.Electric light sources, vacuum electronic devices
Arc spraying molybdenum wire, sprayed onto automotive piston rings, transmission synchronizers, and wear-resistant parts of construction machinery, forming a wear-resistant self-lubricating coating, improving the wear life of components.
4.Welding, electrodes, tooling fixtures
High-temperature tooling, spot welding electrodes, high-temperature hanging wires
wire cutting molybdenum wires are mostly 0.14-0.20mm fine wires, and 0.7mm belongs to a coarse specification, mainly targeting spraying and high-temperature furnaces
1. Pay attention to product material grade
• Mo1 pure molybdenum: conventional spraying, ordinary high-temperature brackets;
• MoLa lanthanum molybdenum (rare earth molybdenum wire): priority for high-temperature conditions, higher recrystallization temperature, less brittle at high temperatures, higher price.
Often, customers will pay more attention to the purity of the molybdenum product. The purity of the molybdenum products we improve is Mo≥99.95%, fully meeting industry quality standards, with controlled impurities Fe, Ni, C content.
2. Pay attention to size indicators
1) Diameter: Φ0.7mm, tolerance, spraying customers usually ±0.02mm; high-temperature furnace customers require stricter ±0.01mm; large tolerance fluctuations will cause unstable wire feeding and inconsistent heating power during spraying.
2) Surface: uniform graphite layer on the surface, no peeling, no cracks, no rust spots, no local whitening oxidation.
3) Weight per roll / coil weight: per roll weight, the spraying equipment has requirements for weight; foreign trade customers are very concerned about the actual net weight, and do not falsely mark weight.
4) Straightness, winding state: no hard bends, twists, and folds, wire feeding by the spraying machine will get stuck.
3.If the product application focuses more on the mechanical and high-temperature performance , pay attention to the following information :
• Tensile strength: not too brittle, continuous wire feeding for spraying;
• High-temperature brittleness: high-temperature furnace customers focus on this, whether it will break upon contact after being heated; lanthanum molybdenum wire has significantly better high-temperature anti-brittle performance than pure molybdenum.
4. Delivery and product packaging
• Delivery cycle, minimum order quantity;
• Packaging: moisture-proof, rust-proof, prevent oxidation during transportation; export pallets, moisture-proof vacuum packaging.
5. Regarding product price
Customers will compare pure molybdenum black wire and lanthanum molybdenum black wire, as well as white molybdenum wire, and how to choose a more suitable and cost-effective molybdenum wire?
1 For intermittent processing, not many jobs, limited budget (for ordinary wire cutting)
It is recommended to choose black pure molybdenum wire, the unit price is the lowest, sufficient, and has the highest comprehensive cost performance. Do not buy white pure molybdenum wire, as it will not increase the cutting life with more expenses.
2. Daily operation, continuous cutting at full load, high current, afraid of frequent wire breakage delaying work time (mold factories, batch processing)
Priority select black lanthanum molybdenum wire. Although it is more expensive per kilogram, it has a long lifespan, less machine downtime for wire replacement, and overall cost performance is the best.
3. The workpiece must not be contaminated by graphite dust; for making light sources and vacuum components
Choose white molybdenum wire (pure molybdenum) or white molybdenum lanthanum wire. This is a process requirement, not a requirement for cutting performance.
If your equipment is used at a temperature above 1200℃ for a long time,and need to purchase "Φ0.7mm black molybdenum wire in the future, the products we can provide are the mainstream specifications in the thermal spraying industry. The Mo1 purity is ≥ 99.95%, the surface graphite layer is uniform, the wire feeding is smooth, there is no wire clogging during spraying, the coating is dense and wear-resistant; it can also be used as heating wires in vacuum furnaces and high-temperature support frames.
We strictly control the diameter tolerance. Each roll provides a material certificate, the weight of the roll is sufficient and not lacking in quantity, and the goods can be delivered quickly upon request."
