Arc welding wire

flamemolybdenum

Overview
Thin molybdenum layers provide excellent sliding properties and high wear resistance for components exposed to heavy mechanical loads. Typical use cases are protective coatings on parts requiring low friction and high wear performance.

Applications

• Piston rings
• Synchronizer rings and synchronizer bodies
• Shift forks
• Other high-load automotive and mechanical engineering components

Production & Materials
Spray wire is produced by a powder‑metallurgical process (Plansee) to ensure high material purity and homogeneous coating performance. Guaranteed minimum purity: 99.97%.

Coating processes

• Flame spraying: Wire is melted in a spraying gun by fuel gas; droplets are atomized by compressed air and form a solid layer on the substrate.
• Arc spraying: Two conductive wires form an arc and melt; suitable for larger areas, thicker layers or higher adhesion requirements.
• HVOF (High Velocity Oxygen Fuel): Produces particularly homogeneous coatings with low surface roughness due to high particle velocity.

Product variants & surfaces

• Diameter range: 1.00 mm to 3.90 mm
• Standard stock diameters: 2.31 mm and 3.17 mm
• Surface finishes: Black (graphitized); Metallic matt (cleaned, oil‑free)

Quality assurance / Certificates

• 100% eddy current testing to ensure crack‑free wire
• Test certificates according to EN 10204 (available: 2.2 and 3.1)
• Guaranteed minimum purity: 99.97%

Advantages

• High availability and reliability
• Short delivery times for standard diameters in stock
• Reproducible coating results thanks to powder‑metallurgical production
