The nickel coating acts as a barrier layer preventing direct exposure of the brass substrate to corrosive environments.\n\n### **Q: Can nickel-plated brass cable glands be used in food processing applications?**\n\n**A:** Yes, nickel-plated brass cable glands can be used in food processing when manufactured with food-grade nickel plating that meets FDA requirements. They offer excellent resistance to cleaning chemicals and can withstand high-pressure washdown procedures with IP69K ratings.\n\n### **Q: What’s the typical cost difference between nickel-plated brass and stainless steel cable glands?**\n\n**A:** Nickel-plated brass cable glands typically cost 40-60% less than equivalent stainless steel versions while providing suitable performance for many applications. The total cost of ownership often favors nickel-plated brass due to lower initial investment and comparable service life in appropriate environments.\n\n### **Q: How thick is the nickel plating on cable glands and does it affect threading?**\n\n**A:** Standard nickel plating thickness ranges from 5-15 microns, which is thin enough not to affect thread engagement or dimensional tolerances. The plating process is controlled to maintain proper fit with mating threads while providing effective corrosion protection.\n\n### **Q: Are there any limitations on temperature range for nickel-plated brass cable glands?**\n\n**A:** Nickel-plated brass cable glands can operate from -40°C to +120°C, which is slightly higher than standard brass due to the nickel coating’s thermal stability. However, extreme temperature cycling may cause differential expansion that could affect the plating integrity over time.\n\n1.
