MS20995CY Cadmium-Plated Copper Lock Wire
MS20995CY is a cadmium-plated copper lock wire that meets military and aerospace specifications, offering enhanced corrosion resistance over standard copper lock wire. The cadmium plating provides an additional protective barrier, extending the wire’s durability in mildly corrosive environments while maintaining the ease of use and flexibility of pure copper wire.
Key Features & Properties:
- Material: Copper (CU) with Cadmium (Cd) Plating
- Specification: MS20995CY (Military Standard)
- Condition: Annealed (Soft for easy handling and twisting)
- Corrosion Resistance:
- Superior to uncoated copper wire due to the cadmium plating.
- Not as corrosion-resistant as stainless steel, but suitable for mildly corrosive environments.
- Ductility & Malleability:
- Retains high flexibility, making it easy to twist and apply.
- More resistant to wear and oxidation than bare copper wire.
- Conductivity:
- Reduced compared to pure copper due to the cadmium coating, but still offers good electrical properties.
- Non-Magnetic:
- Completely non-magnetic, making it suitable for applications where magnetism must be avoided.
- Cadmium Coating Benefits:
- Provides increased resistance to oxidation and environmental exposure.
- Reduces friction and galling, making it easier to handle and install.
- Temperature Resistance:
- Performs well in standard conditions but not suitable for high-heat applications where cadmium plating may degrade.
Common Applications:
- Aerospace & Defense: Used for safety wiring in aircraft and defense systems where copper wire is required but needs added corrosion protection.
- Electrical & Bonding Applications: Useful in grounding and shielding applications where non-magnetic properties are critical.
- Industrial & Mechanical Equipment: Securing fasteners in low to moderate corrosion environments where stainless steel is not necessary.
- Marine & Automotive Uses: Occasionally used in non-saltwater marine applications and classic car restoration where copper-based lock wire was traditionally used.
MS20995CY cadmium-plated copper lock wire provides an ideal balance between flexibility, corrosion resistance, and non-magnetic properties, making it a reliable choice for aerospace, industrial, and electrical applications where a softer lock wire with added protection is needed.
