Leku-Ona offers connectors DIN2353 manufactured and treated with the new coating processes that offer high resistance to salt spray. Since 2010 we have developed a research process that was based on the use of treatment with 320 A3C resistance. This process evolved into A3B (CrVI-free) and then to ZnNi (720 hours). Currently, it has begun to implement a new treatment called ZnNi NEW which is giving us high performance corrosion arriving at 3000 hours

 

APLICATIONS.

• Whenever a high corrosion resistance is required
• Temperature changes do stress additionaly

 

ADVANTAGES

• High corrosion resistance of the coating and base material
• Capable for flaring and bending
• Log term protection, even under thermal stress
• High availability
• Low maintaining costs within the application

SALT SPRAY TEST

Description:

• The following pictures indicate the corrosion resistance of Volz Zinc-Nickel
• plated parts with sealer
• Within the galvanisation process, these parts got handled in a drum

Indication of corrosion:

• Parts with assembled nuts show red rust after 1.872 hours
• This is a forced result as the salt water couldn‘t disappear at this point
• Other parts, where the salt water was able to disappear (as required by the ISO
• 9227:2006), show red rust within the band of 3.072 / 3.216 / 3744 hours
